Thank you for showing the video it really helped me out a whole lot I didn't know where to go on mine but watching your video I understand completely how it works now thank you so much because people like me cannot always run to the shop
Thanks for the video, I thought my brother's plumbing truck was a 1999 Chevy Silverado 2500, turns out it's a 1999 Chevy TAHOE! Looks like I'll be able to get the AC back after I order some parts, we've been through 3 weeks of Texas Hell traveling to jobs! I took out the blower motor and connected it to my test 12V battery, it makes a funny sound, so I know the ball bearings on it are bad. We've been using a 12V DC fan from Autozone to not die in the meantime 😅😅😅😅
I just found this today and found it very informative. Other sites don't show the entire effort it takes to do this job. with my first efforts it leads me to believe I won't "enjoy" the tight space. LOL For those who were less than positive in their comments, why don't they up load a video of their efforts?
@@bnaudio7813 well I got it done. I didn't put the bracket foot under the screw as it would of been beyond my cussing vocabulary. I had to use my palm ratchet to put in the left side anyway and don't think I could of done that with the bracket in the way. My 97 ck1500 has the air bag right above the plenum and it made the opening a little tighter than what yours looked. But bottom line without your video I believe I would still be out there sweating. Thank you😃

When you reattatch the relay at about 16:25 I'd say, first screw in the hole that's directly facing you, then you can bend it clockwise and have it lay flat against the resistor array hole, simplifying reinstallation.
Does it matter which way the resistor assembly goes into the blower box also how do you test the resistor. I installed a used resistor and still blower don't work.
As far as which way it goes. It can mount either way, but your wiring harness probably only has enough movement one way. It's been awhile since I did this. As, far as testing, get your multimeter, ground it and red over each metal filament. Each position on the dash knob creates a different resistance in each position. There are 3 pieces in the system. The dash controller assembly, the element, and the blower motor. If your getting different resistance at the element, then the dash assembly is good sending voltage to the element. If you want to check the blower motor itself, grab a cordless drill battery and run a speaker wire to the motor to see if it blows. Let me know.
So my issue is that my rear blower has a continuous blow on high and air no heat. The knobs won’t control it to turn it off. I have a 99 Chevy Tahoe. Does this work to stop the blower or will I need to do something with the knobs?
tahoe's have 2 separate blower motors and a separate control panel for each motor. which knobs aren't controlling it? which blower motor is staying on?
I have a 1999 Chevrolet Tahoe LT which I replaced the blower motor resistor and the blower motor too, but my heater and air conditioner are still not working. Could it be a relay or the HVAC Control panel/ module that needs to replaced too? Trying to fix this before winter arrives. Thanks.
behind the hvac panel. there is a swtich type of do hickey that goes between the harness and the actual knob in the front. it runs 20 25 on ebay typically. you can put a volt meter on 20v dc and see if you have low voltage power at the element. each position of the control has different voltage. if you have no voltage there then its that do hickey. i will find the name of it
thats it. mine needed it a few months after the element change. watch it when you pull out the hvac controller. the plastic on the sides where it slides in should be brittle by now. be gentle
I replaced my blower motor and now my tahoe dies and the battery starts smoking. Any idea why it's doing that? The wires aren't crossed and the blower works but my battery starts smoking
disconnect the blower motor and if it stops killing the battery, then either you have the wires backwards or the motor itself is wired backwards. if its in the blower motor simply return it for a replacement.
@@MrCoreyTexas Here are some options and issues i have had at the dash control. After replacing the blower element and making sure the blower motor works fine, i ran into the issue the switch did not operate correctly. i replaced this on the back and that seemed good for a few months. www.ebay.com/itm/184389221710?fits=Year%3A1999%7CModel%3ATahoe&hash=item2aee743d4e:g:u1oAAOSwRAVc7gRf&amdata=enc%3AAQAHAAAAsGDFhRDfWh3%2Bk5nK1tVboDspIG%2Fc36ZSYVg8YQqeIy2nCUN70LsS%2BZeeO%2BCG1Np4EoaMCQrPiRqh1l%2F31AOFx%2Br0CZxq3SGJIZ8MGbxaGRAGdUQ2NwgCzkaFv%2ByEDqzAXgIogxqNSO1GcTYLo5XWBAXavBRSh5fbtvaQI%2FTgLnxwgjsCHSRuHxmyIDTlDuZM%2ByLuR%2FMUpZllFw2w%2BtipDWdEoNkYNcDbXnj%2BCNouokeE%7Ctkp%3ABk9SR67fpNviYA
Then it didnt work all the time. took the dash bezel out and then it worked again. what i had happening was the harness was not staying engaged do to the white shroud breaking over time and not staying in the dash. you could just buy a new hvac control piece like this one. www.ebay.com/itm/393122267485?fits=Year%3A1999%7CModel%3ATahoe&hash=item5b87e9c15d:g:MesAAOSwPm5gHP35&amdata=enc%3AAQAHAAAA8DK2%2FxrGoWiBWBh7rCYwVJjUTZEok4iGAkmvkx%2FhcgGzb%2BoZuXElD4JVnqnimyQ4UcpBrKUCBja3QbXLKzumIka0CbFjnFdUG0Xu8cvdAEb9hGbiKUkTVMlVimPehpiHpfLNkxUIE7dncTXkf5MKQKqvWaCXtTXzxkrPxisDNjOWB84Vd%2FV%2BN4hcXiUNS1QVGU3Bf4bpDtQHCxgD5fC%2BC%2FGKeTt0pBSNY3Lz1FJWowjo9kj%2FiFZy5l3vIrBWn5S9O4El85P5mHEidD3Da8i1DTbyyP71o%2Bhdev3Qyyb59iFlcKWS0Pt6%2BAcmlixbyQFLqg%3D%3D%7Ctkp%3ABFBMxOHR2-Jg
@@bnaudio7813 Did you remove the blower motor and put power to it or just do it in the car?? I dont' seem to be getting power to the blower motor ..so how do you test the "Element" do you mean the" resistor" ...truck is twenty one years old low mileage and runs great... probably control switch not a bad job but if I'm pulling some of the dash board apart a new one is going in..Thanks for your help!!
@@martinmoffitt4702 left the blower motor in. just used speaker wire on a cordless battery to power it on. you can use a multimeter with the red probe going across one element and black on ground. turn ignition on, rotate controller and see if you get voltage on the element your probing. each one has a different value. if you have different resistance on each element. then the black part on the back of the control knob is bad. you can order those on ebay for 25ish.
Also, I had more success removing that screw with a open end box wrench rather than a socket wrench, some socket wrenches are longer than others and won't fit

GOOD SHIT BRO I WAS STUMPED TIL I SEEN THIS VIDEO👍🏽KEEP UP THE GOOD WORK
Thank you!
I replaced and still working only on the high speed option.
THANK YOU SIR FOR YOUR HELP!!!
No problem.

Wondered where air cabin filter is? I have this same setup and don't see any videos showing for this type and year.
This is for the '96-'99 body. Cabin filters started in 2000.
Is the relay you removed on the left for the high speed only on the blower?

Sir what was reason for replacement?? Original complaint/diagnosis Thank you!
the blower was not blowing. tested it with a 12v battery and it worked. so it then has to be the element or the control switch in the dash.
