MY REPAIR WAS FREE!
2006 BMW 330xi fan not coming on and caused overheating. Tried and tested everything in this video and still no fan. My solution: Multimeter test ground and power from thermo switch to fan plug. voltage to fan was good as was the ground. A third wire, REFERENCE WIRE, had no voltage, the reference wire has to put out around 4-5 V. My reference wire had rusted in the harness and caused a short(harness is located along the right side under the radiator shroud). After inspecting the harness, I came across a discolored spot and decided to slit the wire to see any damage, sure enough, the wire was hanging by a strand of wire. I spliced the wire, soldered the connection again and Voila! Fan is alive!!!!! Maybe you'll get lucky and this is your cause.
You are honestly like the best channel on UA-cam
Thank you guys, you guys have save me a lot. My whole cooling system is not workng, no codes. Its like that part of the can bus is not responding.
Thank you so much for your assistance, Im sure you saved me a lot of money by watching your informative video.
so, question??? first we drain, then we refill and bleed it and then we remove the old sensor and install new one, or first remove old sensor, install new one and then drain refill and bleed???
Is this the same sensor which tells the engine temperature on the cluster guage ?
Sir I just want to say that your videos are not detailed enough most of the time u partially show how to do the job and never actually follow all the way through can you fix this?
Have you done a video on replacing the radiator fan relay? I can't find it on this channel or your other channel.
Finding this is like finding the city of gold 😂
Yes, where is this relay located???
ua-cam.com/video/UDGOagBRp-E/v-deo.html
this one?
I have a 2007 BMW E90 built in August 2007. The sending unit is just below the oil filter on the head. It does not have a sending unit on the lower radiator hose. My fan is acting up. Sometimes it comes on with the air conditioner. Sometimes it doesn't. If I unplug it from the sending unit sometimes it'll come on on high. Sometimes it only comes on when I plug it back in and only runs for a minute or two and shuts back off. Can you tell me what's happening here? And is there a relay for this car for the fan?
Anyone knows where is the fan relay for 2015 X1 xdrive28? I changed fuse and temp sensor, the fan still doesn't work, but can't find the relay... Thanks
Good evening.
Very nice video.
Maybe you know.
When i put the a.c for 2 sec work and stop again.
Generally never do the same think.
Have you got any idea?
Hi. You mention the relay. But where do you find it?? (2005 320i e90 N46). We have looked all over but don’t find it? (Fan turns with direct power, fuse is ok)
what temp do the fans come??????????????????????????????
This is not an e90 335i. Every google and youtube search I do for 335i or N54 lands me on results of you guys working on anything BUT a 335i with an N54. I'm glad you're building up a following on youtube but that seems to drive search results to your videos, and you're doing it by spamming keywords in the description as is often done on craiglist.
My problem as well my E90 328i is nothing like this there is no sensor in any hose nor is there that 5 fuse holder in the fuse box??
@@ronmontana7658 Well they haven't fixed the spam after my last binge of reporting them. Maybe you could join me.
Hey i have a question , my fan is currently not working, it spins for a few seconds only if its disconnected after a few seconds it stops , i already replaced the relay and nothing so if you could give me an advice i will really appreciate it.
problem of the radiator fan not comes on when AC is turned on BMW or comes on with low speed? could you help me to find the problem?
My car haven't that switch in tha hose....why? 2008 328i sedan. I checked fuse and coolant temperature sensor already.
2006 bmw 325xi fan doesn't come on until i remove the fuse and then put it back then the fan starts working. Is almost like it resets something
Hi there, where does one find the radiator fan relay for a BMW E87
Thanks for sharing. Great vids!
I need a new fan for my 07 328i coupe with standard transmission. The fan you referenced says it’s for an automatic trans. Can’t find it that says it’s standard only. Do you know where to find it? Thanks. And thanks again for all your vids.
Can’t find video for bmw fan relay location
I've got a 645ci that the fan runs for about 10 seconds at cold then sets off a engine malfunction on the entertainment screen and shuts the fan off. Vehicle will overheat and fan will not respond to activation in scan tool. It sets off a DME Fan Activation code in the scan tool. Any clues?
On my e60 520i when I set the ventilation temperature to minimum the radiator fan is not working and the car is overheating. When I set the ventilation temperature to the max, the radiator fan works and the car is not overheating. What can be the problem
like the good stuff that you guys do.
Hi can you give location of fan control sensor on 325i 2007 petrol e92 please
I wonder why my 2007 bmw 328i doesn’t have that sensor?
At what temperature does fan start working. My e90 2005 m47 never turned on fan max temp i saw were 96celsius, is that low for fan to start?
Can you tell me the location of the fan coolant temp switch on the 1 series (f20) 1.6 diesel? Thank you
When i removed the sensor the fan stardet spining. So it says that my ssnsor is bad?
Exactly
Thanx a lot guys
Would the fans not working cause the car to go into limp mode?
absolutely
Thanks a bunch for your videos. You guys are fantastic. I have a question regarding the cooling. Hope you'll see my comment. I have a 2007 BMW 328i sedan. The fan won't engange. I've tested the wires, coolant temp sensor, thermostat, water pump and fuses. Replaced Thermostat with OEM, Coolant Temp Sensor, and Bled the system. The Fan will not engage even when the temp rises all the way to 220 deg Farenheit (104 c). So, I thought maybe the fan is bad. Side note. My Beemer has a temp sensor at the radiator outlet hose but there's no connector to it. I've looked everywhere following the harness down to the inside of the cabin and no Connector. Anyway, I bought a new coolant temp sensor (the one mounted at the engine). And the way I tested the fan is as follows. When the engine is running, if I disconnect the Coolant temp sensor connector. The fan automatically kicks on. That's what's supposed to do, I'm told. But I wanted to make sure the fan is in good working condition by connecting the old temp sensor outside of the car (The new sensor installed in the car so the coolant wouldn't leak), then I started the engine. I applied heat to the old sensor with a heat gun and while measuring the resistance as the sensor started getting hot, the fan kicked on when the sensor got to around 208 degrees f (98 c). That proved the old sensor was working properly and once it's hot, it commands the fan to engage. Problem is, once the sensor is installed in the engine and temp gets real hot, the fan won't come on at all. Sorry for the long message, any help will be greatly appreciated. I'm at a lost here.
Did you ever figure this out?
@@OmarGUSMC Sure did. After checking everything I mentioned and bleeding the system. Making sure there were no leaks. I decided to take it for a ride. I connected my Maxisys Scanner to see live data. 15 mins after driving the car. The temp went up to 228 deg F. Then all of the sudden, the Fan kicked on. I suppose the coolant needed to recirculate long enough to get the Temp Sensor to detect the right temperature. 👍
@@pedrodelasancha516 hello, how's the car behaving? Does it mean the problem is the poor circulation of coolant and it doesn't reach the sensor in your engine?
Hello, I'm looking to know if the motor that powers the fan (placed in the middle) can be inspected and diagnosed for wiring mishaps. Any help will be appreciated. Thank you.
Can ohm out each winding
EXCELLENT
Short video but I swear it took 10 mins to start explaining
does X5s have relay?
Where is the relay?
335i n54 does not have the sensor
Good video, but not enough help. I have a 2006 3Series with an N52 engine. I have replaced the Fan assembly, Aux fan switch, Thermostat, upper and lower hoses. I have verified constant voltage in red/black wire and good ground on black wire. Fan still doesn't run, ever. A/C on or off, at start-up or after running until it overheats. I was under the impression the relay was incorporated in the fan assembly. Need some in-depth help on additional relay and wiring harness. Help/suggestions please.
Having the same problem with my 325i cant get the fan to turn on and if it turns on it rotates slowly and then stops working again basically everything is brand new might just have to end up taking it to a shop and get taxed.
After searching this and other forums, found that the answer was to clear all error codes. Hacked the hidden menu to monitor actual temp while running and her behaves as expected now.
@@griffenjacobsen8541 thank you , going to have to find out what I have to do , but is there any good videos on how to do that ?
@@abrahamvera6366 yes. There are several UA-cam videos on the hacking the hidden menus. I'll post a link but you can search for them. There are great.
@@griffenjacobsen8541 thanks a lot dude , going to look for videos and to try this I’ll let you know if it went back to normal or if I’m still having troubles but by clearing all error codes is that just by connecting the obd2 reader and clearing them ? Then proceeding to monitor the actual temp ? If you can post a link I’d greatly appreciate it !
Seems like my BMW doesn't have a sensor on that part anywhere 🤔I have a 2009 328i
Im having the same problem with mine. Im wondering if its the thermostat.
Where is the relay
Ya nice story but my 08 328i E90 is Nothing like this??
They don't care. Help me out.
Where can I find the Fan relay?
Did you find it? I can’t find the other video on the other channel they talk about
I have 330d and it's next to the DDE (ECU)
What in the hell did I just watch I could barely understand him to start with then and then he keeps telling us to go to his other channel to find out what is wrong what the hell
Hi can tell me what could be the problem with my bmw top pipe to radiator is hot bottom one with fan sensor just a bit warm after 40 min drive and fan not turning on?
Chevy same problem here
@@foxxy4191 it was the thermostat for me
@@foxxy4191 bleed the cooling system because if you have to much air in the system thermostat won't open ua-cam.com/video/MDrEn1qmJOo/v-deo.html
It wasn't helpful.
Because it's not the car you searched for? Yeah, they get that a lot.
ok
Talk to damn much you didn’t even put the fan on
Why is he talking like aquaman?
Wfhen I visited India, all the people I talked to in Hyderabad prefixed nearly every statement with a, "sir". It's a very respectful and polite way of talking.
Very bad English 😅
That's not true my e92 320i n43 engine does not have that heat sensor in the pipe by the fan and it don't have that black box
