Replacing "Mode" Switch Motor - Lexus GS
Вставка
- Опубліковано 3 сер 2024
- This video is made as a guideline to show you how to replace the mode switch servo motor on a 97-05 Lexus GS. This also applies to most other late 90s and early 2000s Lexus model cars. The process may not be identical but it will be similar.
I hope it was helpful!

Great tutorial. Thank you. I'm a female and did it myself. The mechanic said he was going to have to remove the whole dash to get to the actuator and it would take 8 hours to repair. I am so happy I was able to do this on own.
Wow, yeah that's not true. Should be that big of a job for one if these servo motors. I'm glad the video helped and that you were able to complete the job by yourself!
1 of the best DIY videos I've seen to date! Its so hard to find anything DIY about these Year/model Lexus GS300. Much Thanks!!
Thank you!
Thanks for the very detailed video. I'm a total novice when it comes to car repairs, and I would never have attempted this fix without your video. You made it easy. Thanks! Power door lock actuators are the next issue. After today's success, I'm feeling like I might give those a go too.
Awesome! Good luck on the door actuators. I had to replace all 4 on my Lexus and it's not difficult but it is tedious. But it's not any more complicated than this job for sure.
Thanks much took me only an hour to do this operation thanks to you!
Hint: when ratcheting the back screw in use electrical tape(i then used a lighter to tighten up the grip) to secure the screw to philips fitting/socket
Awesome, I'm glad the video helped!
And thats a good tip, thank you!
Thanks man, made this install fast and easy. One thing I would add is that a stubby screwdriver works to get out that tight screw if you don't have a swivel ratchet.
Thanks! And yes indeed, thanks for adding that!
My wife's car (03 GS 300) has this exact problem. Only vents through the defrost vents. Thanks for the DIY video. Exactly what I needed.
Awesome, I'm glad the video helped out!
I was able to get the servo out thanks to you, whoever had the car before me never replaced the third screw in the back so I had a hard time putting the servo back in without the arm falling out if the slot. Also I just reused the old servo, you can open it and clean the potentiometer and contact arms inside with alcohol and use some new white lithium grease. Just make note of the arm position before opening it and be very carful with the clips holding it closed.
Awesome! And good to know about reusing the old motor!
maybe I got lucky but I just reinstalled my new motor with only 2 screws. When taking the old one out I just could not get to that third one so I ripped the old motor out. It's running fine with two screws! 2001 Lexus GS 300 - just finished the job a few hours ago
@@phineusmcclintock1 yeah 2/3 should be just fine. I wouldn't worry about it
You are an excellent teacher!
Thanks!
Nice work, thank you very much, huge help for me!
Absolute legend. Thank you. Worked perfectly
Thanks!
Just finished, worked like a charm. Thanks!!
Awesome!
I’m not mechanical inclined at all what should I spend on a gs300 99 with 190k he’s asking 3k but I want to spend less if I’ll have to fix something major
That's a fair price but you have to make sure it doesn't have issues. Either bring someone with you that knows these cars or have a mechanic go over it. Just know that they hold their value just because they have a 2JZ in them. So you can rarely get them for dirt cheap.
You should do a valve seal, and spark plug video on the GS300!
I'll add that to the list, maybe one day I will!
Best ever removal . Thanks
Thank you!
Love the how to videos man. Thanks for making them! Pls make more!
Thank you! I will keep them coming ;)
Great, very detailed and informative 👍
Thank you!
Auto Fix hello I’m looking to spend 2500 on 99gs 300 with 190k on it should look for anything or how much would you shoot to spend on it with repairs in mind to get it back to condition to hold up for 2 years or so
I have this problem on my IS300H.
Defrost doesn't do his job and it takes 1 minutes for the heater unit to switch on after starting the engine.
Allo it dont keep in memory the air co or heating configuration.
Thank for this usefull video.
Superhero. Thank you!
Awesome!!!! Thank you!!!!!
Thanks
This was very therapeutic to watch to say the least 👀
Thank you!
@@AutoFixYT any advice you can give on how to fix your cigarette light in your car? Specifically 2003 gs430 lexus?
And also why my back doors no longer unlock when using the alarm key or the front door buttons? 😞
Figured out my cigarette lighter. Issue boss.. Its a fuse box thats actually behind the emergency brake. 15A & I fixed it. Thank you anyway. Now on to problem number 2.
@@CL2125 Yup, a fuse is the most likely cause. If it keeps popping make sure you don't have a short anywhere in the plug or on the wiring, and make sure that whatever you're plugging in is not overpowering the outlet.
As for the rear door locks... door lock actuators are very common to go bad on these cars. Get two new ones and you'll be all set. They're not difficult to install but not the easiest either. I had to replace all 4 of mine.
@@AutoFixYT thank you so much and please continue to give us more content! I'm about to go study you exhaust replacement video.
Fixed! Thank you! But I could NOT get that far bottom third screw, even with the tool I just couldn't do it. My arms are so fat and I am so wide I feel like I just would never be able to get it so honestly I got the first two then just ripped off the old piece breaking the third screw, then I finally unscrewed it. lol. When reinstalling I just went with two screws, I think it should be fine - this was so easy because of your video that if it causes problems ill really spend the time and go back in and add the third screw.
Awesome! 2 screws should be just fine
My mode isn't working. Bought a replacement servo motor and when I went to test, it didn't move. I only moved when i plugged it in and started the car. But when i went to change modes it won't move. Any idea what to look for next?
Hi, first thanks for sharing and helping in a simple way. The GS300 has 2 servos? If yes, how do you access the other one?
Yes these cars have multiple servo motors. I believe the other one that you're looking for is also behind the dash there somewhere.
What are the type of screws? Size? I can’t find mine when replacing.
What is the part number on the white connector that plugs into the blend door actuator? I have an early 98 GS400 that uses 8710630370 which has been superseded by 8710630371. So it's not plug-and-play for me. I'll need to de-pin the old connector and use the new connector.
Hey this is a great video. I'm assuming the passenger temp servo is the black box located below the mode correct? I'm getting a grinding noise now, so I want to replace both at the same time. Do you have any advice on removing the extra servo? It seems its behind the white plastic duct. Last how has your rock auto part held up? I was thinking about going with OEM
I don't know which one is the passenger temp actuator is. Make sure you are not accidentally replacing the recirculation actuator.
Also, my budget rockauto part has held up perfectly fine! I still have it in the car and use it all the time. No issues for me!
@@AutoFixYT The recirculating servo is next to the air box/cd changer. I'm talking about the servo that's below the mode that you replaced. I tried to find photos on club lexus to confirm but they were removed. This is a great video! Thanks. I'll look into the budget servo motors
@@frugalfreddy81 ok that makes sense. Yeah that might be it then!
thanks helped save 100 dollar as mechanic said whole dash needs to be opened 6hrs job
Nice! I'm glad the video helped!
@@AutoFixYT update i tried but the new one i install no movement my ac is fine problem is its stuck on vents im fine with that but when ac is of i feel hot outside air coming from vents if big truck is in front i can smell their smoke that's what annoying me what should i do to my gs just to stop the outside air im fine with rest of the things as car is old i understand it won't be perfect please help
@sameersyed5308 when you turn the air completely off, those cars automatically close the recirculate door to block outside air from coming in. Maybe the recirculate door actuator is bad too?
@@AutoFixYT where is the location for recirculate door actuator i gave up now i stumble again to start to fix it
@sameersyed5308 I am not sure but it should be around where the cabin air filter is. Usually the recirculate door blocks the air right after the cabin air filter. Recirculated air does not get filter in most cases.
Hey! 1st thx for ur video.
2nd, do you have any thoughts on why my 03 gs300 makes "creaking noises" when i turn my steering wheel? Not always, but iften. Thanks.
That is most likely a ball joint or a tie rod end. But probably a ball joint. Check those things first. They will do it worse when it's humid and/or cold.
the one you purchase is the $17.35 correct? and how do you feel about aftermarket vs oem on parts like this?
I don't remember exactly how much mine was but that sounds about right.
I think that if you're on a budget it's worth trying aftermarket, especially if the part isn't that difficult to replace.
thanks for the vid. my problem is that everything is blowing, to include the blower and heat, but i have no cold air. freon and compressor all in check. I need to find out which to replace.
Weird. Check that the compressor clutch engages as it should, also your cooling fans should come on as soon as you turn the AC on. If not both then at least one of them should stay on. Also it's important for the pressure in the AC system to be exactly what it needs to be. Not more not less.
@@AutoFixYT Appreciate the swift response. Will look into it.
@@HALFAMAZINGTV you could also have an issue with the blend door but if you are able to control the temperature of the heat, more or less hot, then the blend door should not be the problem. But if you only get full hot air no matter what temp you set it to then maybe it's your blend door that's stuck in the open position. Just a thought. Probably not the cause of the problem though.
@@AutoFixYT if it is any help, it actually all started when i drove cross-country from Vegas to Florida. I would hear a whine or small animal moving in my center console. It would be cold, then eventually become warm. I had the pressures checked and freon added. Now, when I turn the heat up while driving, it has a lound whine and ticking until i turn off the system. I am pretty sure it's one of those servos or blower motor resistor. Thoughts?
@@AutoFixYT I have this issue on my passenger side. I adjust the temp to lowest setting and it's still full blown hot air. Where do I go to fix the blend door?
Hi, I have the problem that it doesn't blow hot on the passenger side. This is a right hand drive as I'm in the UK, The side with 2 servos on the left side as you look at it are working OK as I removed them and tested them. What does the single servo on the drivers side control? I have looked everywhere on the internet and I cannot find what it does. i would like to sort this before bad weather comes. Is there anything else that can affect it like ecu or control problem?
No it sounds to me like your issue is just something to do with the blend door actuator. Locate the heater core box and the blower motor. Near that should be two actuator that control heat. One for driver's side, one for passenger's side. While pressing the temp control buttons, listen down there for noise and locate which one is working and which one isn't. The one that isn't is your culprit. Replace it and you should be all set. It's a common issue on these cars.
I cannot tell you specifically which one it is because I've never had to replace it but that is how I would locate it.
Hope this helps!
Different question pertaining to the glove box itself. Does it have a damper which prevents it from slamming down when you open it? I know most do but I cant see one + google has not yielded any results for me.
Yes there is one but I'm not sure where it's hidden. If you take the glove box out I'm sure you will get to it somehow, but it's not out in the open like on most other vehicles (I guess Lexus thinks of all the small details too lol).
It might be built in to the hinge somehow. Not sure though. But there definitely is one.
Hello, what is the red wire? my wire is damaged (disconnected )
I don't know what it is. You'll have to get a wiring diagram and see what that wire does. But no matter what it does, just fix the wire
B1443 and B1447 ... what do these codes mean?
Would I need to do the same procedure if the temperature does not change from hot to cold and vice versa? The passenger side can switch from hot to cold with no problem but the drivers side will only change if I turn the car off, let it the engine cool off and maybe get lucky for a change in temperature when I start it back up. Weird situation and unfortunate because I need the heat in the morning since it’s cold but then it gets to around 80 in the afternoon and I need the A/C but it won’t change. Let me know what you think. Thanks
It would be a very similar procedure, except that you have to find the location of the blend door actuator for the driver's side. The blend door is what blocks and unblocks the heater core to allow or block the heat. Because this car has dual climate control, it should have two blend doors. Find the location for the driver's side one. First test the actuator (motor). Hopefully that's your issue. When you test it make sure you test it while it's still mounted and connected. You want it to be under load and in its original position. If it skips around or doesn't work at all, or maybe it works very slowly, then it'sdefective. If that works well then there may be a problem with the blend door itself. I'm not sure of the location of the blend door for the driver's side, but some digging on the internet should get you that answer. Hope this helps!
Try CL, this post tells you about the different servos.

But you'll need this video anyay. :)
My AC only blows thru the defrost vents and a bit from the two in front. no air in middle or back vents. would this be my problem ?
Yup that’s your problem! It can’t switch between modes because the actuator went bad.
Can you do the other servo motors in that area?
I will if they go bad lol so far they're good
So replace this if I only get air blowing from the front. I don’t get defrost or feet mode. Just that part?
Yup that's it!
@@AutoFixYT Thanks! Great video
Is this a share part with Toyota? My 94 Corolla with automatic ac do suffer the same issue, ac coming out on all vents and defrosts.
Lexus is made by Toyota, so yes, they all have the same parts. Lexus parts are often stamped with a "Toyota" stamp.
My lexus is staying cold on driver side and hot on passenger side what motor do i need for that
You need the driver's side blend door actuator. Not sure exactly where it's located but somewhere in there on the heater box.
Does this same repair work for the GS430? I'm trying to put the servo motor in but can't. I tried changing modes already, I think I might have it might be a different direction than the GS300
It should be the same thing
@@AutoFixYT Thanks for replying so quick. I just figured it out. Thanks. Gotta get the 3 screws in
How do you remove wire with green tap?
For some reason the driver vent is blowing hot, but the other vents are blowing cold air. I had the heat on 85. Any idea why this is happening? I'm guessing it's the Air blend servo, do you know how access it?
@@jmhellison I'm not sure which green wire you're referring to.
As for the heat issue, yes that's your passenger's side blend door actuator, aka servo motor, that is stuck on cold. I'm actually not sure where it's located unfortunately :/ I know it's somewhere next to the heater core box but I can't give you a precise location, sorry about that!
Hi, very useful video. my 2001 GS300 no air from center vents, air coming from side vents only. will this solve my problem?
Also, you think the mode servo is the culprit here? thx in advance for your help
The mode servo selects where the air flow goes. So... can you switch between defrost, vents, and floor? If yes, the mode servo motor isn't your problem. If you cannot change the air flow then that is your problem.
@@AutoFixYT pressing the mode changes to defrost and floor etc. so mode servo isn’t the problem. could you suggest what to focus on? seems the door to center vents is not opening.
@@kamhanmas hmm that's a weird issue then... the center vents are also activated with the side vents but maybe it has a separate thing that activates them? To be honest this is hard to answer because I've never heard of this issue and without physically disassembling and diagnosing it's hard to give an answer. Sorry :/ I know this isn't much help but I've honestly never heard of that issue haha
@@AutoFixYT you think something could be stuck there and preventing center vents from activating? I heard the same noise coming from the dash like something was stuck before no air from center vents. you think should still visually look at the mode servo following your video? thanks for your time and help
When on heater mode my Lexus rx350 blows hot on passenger side but cold on driver side.. any idea?
Sounds like the blend door actuator for the driver's side went bad and is stuck on cold.
would this be the same process for an 06 is350? part number if you may know?
I don't know, sorry
I took out the old mode servo, then wired up the new one before installing, it worked great, then i installed and reconnected new servo and it doesn't work. Did I blow a fuse? And if so, which one and where is it located?
As long as the wiring is still ok, it might not be a fuse. However that is always a good place to start. Look in your owner's manual and find the fuse box location for the interior fuses. Then on the cap of the fuse box there should be a diagram that tell you all of the fuses.
Also, make sure you didn't bind up the little motor when you installed the actuator. If it's bound up it won't move.
@@AutoFixYT Thank you so much for responding. Car was stolen last year and they took the owner's manual and covers to the fuse boxes, so I'm buying those from ebay (probably the guy who took them), and will then be able to check fuses.
I tried the servo unmounted and still doesn't work. Guess I need to figure out how to check the wiring, assuming I might have pulled a wire loose from the connector? Guess I'll have to learn how to use a multi-meter?
Lexus provides the owner's manual in PDF form on their website for all of their vehicles, so before you buy it consider that since it's free and you can have it on your phone at all times.
As for the fuse box covers, eBay or the junkyard are good places to find them
I have my 2000 Lexus Gs300 and the AC doesn’t blow on the feet, only on the upper vents even if i change the mode.. would this my issue?
Yes thats your issue. I had the same exact issue happen to me. It's very common on these. Mine always got stuck on the vents and my feet were freezing in the winter lol
@@AutoFixYT hahaha! Same here! Thank you so much for your great content! . Would this work on a 2004 Lexus RX330? Thats my wives car and she has the same problem. And do you happen to have a link to the servo for that car? Or the part# maybe?
@@VictorAriasPiano Yes it's most likely the same issue. You'll have to look for a video or dig around to find the motor, but it should be in the same general location. I don't have a part number but you can look it up on rockauto, they most likely have it there
@@AutoFixYT ok great! Thanks so much for your feedback!
@@AutoFixYT I just subscribed and I will be watching more of your videos! Do you have like a Lexus GS 300 do it yourself maintenance video types of things? Like simple maintenance that I could do myself?
where can i find this part at. most stores dont have it
Rockauto.com. I linked it in the description.
@@AutoFixYT ok thanks. one more question. Im looking for the driver side master window switch. And help?
Thank You 🙏. Do you have a video to replace left side temp servo ?
I do not unfortunately.
What mode is it in to put it back
I don't remember if I had it set to a specific mode. Made this vidoe years ago. If there is anything to be specified then it's in the video.
Is this the same motor that controls the hot and cold? My driver side is stuck on hot
No. This only controls where the air blows. You'll have to look for the blend door motor. There are two actually. One for the driver's side and one for the passenger's side. They should be right on or near the heater core
@@AutoFixYT Thanks for the reply, I’ve been looking on Amazon. Can only find mode motor
They must be somewhere but I personally don't know where. I'm sorry :/ but look at videos of these motors on other Lexus and Toyota vehicles of the same time period, they might help
@@AutoFixYT Thanks for your help.I’m going to pull the part out tomorrow. I believe from what I’ve read it is on the driver side above the gas pedal. Just bought the car today, has 257k miles but still going strong!
@@Aku112811 Yeah that sounds familiar... hopefully you succeed!
And awesome! These cars will go for a long time with just basic maintenance
Hey man my 2003 Lexus GS300 only blows cold on the passenger side😭. What need replaced to make it all blows cold? The mode doesn’t work either it blows out of all the vents a little. Help 😭
Well for the mode selector just do what I show in this video and you'll be all set. As for the cold and hot thing... I think it's a blend door issue with the dual climate control. Since it only works on the passenger side, first check that you have enough refrigerant in the system. If you don't, that's what can happen. Assuming you do have the proper amount, you'll need to replace the blend door actuator for the driver's side (but first make sure that's actually what's wrong), maybe the door itself is broken or stuck.
If you fox those two then you'll have working HVAC again!
@@AutoFixYT Thank you sir, RockAuto a good place to get all those motors?
Yup that's where I got mine
The problem with mine is one side (driver side) works just fine though all modes and temperatures but the passenger side only blows cold air no matter what. Whould this fix my problem?
No. It sounds like your issue is a blend door actuator/motor. There are two. One for the driver's side, one for the passenger's side, because of the dual climate control.
Your issue must be the pass. side actuator, it's probably dead and stuck on cold.
@@AutoFixYT Thank you so much for your reply I'll look into replacing that immediately!
My ac compressor is spinning, I tried to added ac pro but my gauge went to red. Now I noticed my control climates aren’t switching. Lights and lcd works but nothing switches. I think it’s affecting my ac button. What could it be?
Ok start off with checking the pressure in your AC system. Either buy the full gauge set or have a shop check it, because modern AC compressors won't turn on if the system is slightly undercharged or even slightly overcharged. So make sure your high pressure side and low pressure side are within spec (not just the high side). After that, if the AC still doesn't work, you can start diagnosing further. Make sure the compressor is getting a proper signal to turn on. If not, it's an electrical issue. If it is getting a proper signal and it has the right amount of refrigerant in the system, have the compressor checked out because it may be a bad clutch or have faulty internals not allowing it to turn on. Hope this helps!
Auto Fix thanks for responding. When put the full gauge on the low side, the gauge spikes to the red zone. I think it might be electrical because why would my front and rear vent mode would stop switching all of a sudden.
@@Iceyboy300 the gauge shouldn't spike over the normal pressure. Check the high pressure side too, it's important. As for the vents, yes that's an electrical problem
Auto Fix Alright I guess I’m going to drop the car off at the dealership tomorrow. I’m not sure why it’s on the red.
@@Iceyboy300 Let me know what the problem ends up being! I'm curious haha
Where did you get the led bulbs ?
Amazon
Do you remember the bulb number ?
@@tylerjones4215 Which bulb are you talking about? I said Amazon because that's where I get all of them lol
@@AutoFixYT the one that’s on the bottom beauty panel to light up the floor board I believe u had a red wire dangling with it
@@tylerjones4215 Oh yes sorry, those are 74 bulbs, a.k.a. T5 bulbs
Hmm so I did replace this, everything is fine besides still no floor heat. Modes change but I get clicking
Ok in this case there may be something mechanically wrong with the doors that open and close. You're gonna want to test those out by hand. Also when you have the actuator out, press the button to activate it and hold pressure on the shaft with your finger, and see if it clicks. Maybe it's bad internally and can't hold much pressure? Such as the gears being stripped. Just a thought. Not sur what else could be wrong.
@@AutoFixYT There are multiple servo motors. 3 on the passenger and 1 on the driver
I didn't know there were that many but thinking about it it makes sense. 1 for the driver's temp, 1 for the passenger's temp, one for recirc, and one for mode.
What the parts number
Part is linked in the description
My ac blows hot air even after I added freon
99Gs 400
Could be a bad blend door actuator. Don't add refrigerant unless you know it needs it. An improper amount can cause damage to the system. Have it checked with a set of professional gauges so you know the pressure on the low and the high side.
