How To Install Fan Speed Control Blower Motor Resistor Chevy Silverado GMC Sierra 99-06 1AAuto.com




What do you think about this video?

i3sm3: I changed my blower motor resistor in my 05 Trailblazer and all speeds worked, but after a few hours only speed 5 works? Should I replace the blower motor itself or could it be the fan speed control resistor/switch?

teamsiems: Thanks for the video. I was able to change my resistor (2005 Yukon) in less than 1 hour. I didn't/couldn't have to take out the center screw on the outer casing. I took out all but and pulled down the plastic. Just remember the 2005 Yukon has the 4 hole version of the resistor (costs $25 more).

Allen Holley: Thank you for the help, The 3 levels of speeds of the fan wasn't a concern of mine then #4 and #5 acted up and were not working all the time and thought this could be a costly repair to my truck. The truck has 241,000 miles on it and sometimes wonder if it's worth repairing. When I pulled up this video it showed me exactly what was happening to the truck and with a little help from this video I was able to repair this at a low cost!! The tutorial was very precise and helpful to make this a quick fix. Thanks again and I have used this site and will continue to use this for future repairs!! 

Maco Williams: Ok. So i recently bought a 2005 chevy silverado half ton. I drove it home and i turned the ignition off. but the A/C was still running and it ended up draining my battery. I pulled the cable and the A/C turned off as expected. But id really like to get it fixed. Is it my blower resistor? It wont even go to any other fan speed. It just stays at the same constant speed.

StealthBomberr: I just did this for my '01 GMC Sierra. The switch went from 3-5 to just 5 then it just stopped working all together. And I just did this by myself in less than an hour! Thank you so much! It saved me a lot of money and plus I like to learn to do things by myself!

1A Auto Parts: Usually when that happens it's the sign of the blower motor resistor going bad. We sell new ones on our website 1aauto.com 888-844-3393

Joseph Messina: my 99 gmc sierra 1500. my 4 wheel low is not working. just the high. is the problem the transfer case switch?

1A Auto Parts: @boominator6464 We currently do not have a video on this vehicle. It may be a similar process.

1A Auto Parts: @txrelichunter This is for the generation shown at the beginning of the video which would be 2000-06 plus 2007 Classic Style for the 2500 and 3500.

1A Auto Parts: @TheMan16111 It sounds like the blower motor resistor may have gone bad. Usually when they go bad you start to lose the lower speed settings. Hope this helps you out.

Brandy Brockman: 77biglow I had the same issue with my 99 S10. What my problem was is the blend door is an electronic switch. My connector going to the switch come loose causing the blend door not to open. Plugged it in and bam fixed.

txrelichunter: my 99 2500 Chevy looks nothing like this.. is there two versions?

Casmith Smith: My 1990 GMC V2500 suburban is having heater issues. The heat doesn't come on at all but as I am driving and the truck warms up I can feel (a trickle) of warm air with no force behind it. are their any tests that you know of to see which part in bad besides just ripping it apart and checking piece by piece?

1A Auto Parts: Thanks for checking us out. Have a great day. 1aauto.com 888-844-3393

Jordan Cronk: Thanks a lot! Second time one of your videos have helped me by one, saving me some money, and two, fixing my car!

1A Auto Parts: The actuator for the blend door could be bad, or if it happens when the AC is on you may need to re-charge the AC system. Hope this helps you out. Have a great day! 1aauto.com 888-844-3393

1994mccracken: i have a 01 silverado that blows hot air on 1 and 2 but 3 4and 5 blows cold any ideas why

1A Auto Parts: It sounds like when the repair was made something was hooked up backwards. You may want to re-check the connections and possibly try to reverse this to see if it will solve the situation that you are having.

1A Auto Parts: If the blower is not blowing hard enough, either there is an issue with a blockage in the HVAC system or it could be an issue with the motor/resistor causing it to blow slow.

1A Auto Parts: You may want to check the freon level to see if it needs to be charged, also check to see if the AC clutch is working properly when the AC is on in the cab. Hope this helps you out. 1aauto.com 888-844-3393

1A Auto Parts: @ncrdisabled I don't have a venture right now to do a video. The resistor on your venture is probably located in about the same spot as it is on the truck in this video. The procedure is probably about the same as well.

nkko11: Thanks Ill call on Monday and get it ordered!!!! You have my business!!!!!!!!!

Leo Bowman: Great video... now I know what to do...My 2002 Silverado ac doesn't work on speed 2 ..Now I'm going to buy the resister and replace it myself...would have cost me over $400 bucks at the dealer!

1A Auto Parts: It sounds like it could be the blower motor resistor that may be acting up.

1A Auto Parts: It should be very similar of the same as shown in the video.

boominator6464: Would this be the same instructions for a digital control a/c-heater unit on a 2005 Yukon XL Denali???

MsMarieH1: Thank you for the comprehensive video! This looks very helpful and actually makes it look like this could be easy enough for us to do ourselves instead of taking it to the dealer. We've lost our bottom four speeds on our 2001 GMC sierra z71 blower. Would love to have this be a relatively inexpensive repair!!

trkmkr66: i have a 2004 silverado and had to change the resistor. got the new one at local parts store. what i have noticed with the comments on here is that no one is mentioning the plastic cover that is over the resistor. my new one was made different as far as the connector on the new resistor. the old one was at an angle and the new one was straight. the new one would not bolt back on with out the cover. so i had to cut away most of the cover to get it to slip over the new resistor.

Toasty504: will this work for a 06 chevy trailblazer?..pretty much same problem as you had

eAk: Thank you!!! This video help me replace this part on my 03 suburban. saved me tons of money

Joseph Messina: dobyou have a video on hke to install a antenna on gmc sierra. cant get to the stereo

77biglow: I have a olds Bravada 1999, my heat blows fine, but when I turn it to cold for the air, it continues to blow out very hot heat. What would you say is the problem!

1A Auto Parts: You may want to check the blower motor resistor.

alesserfate: anyone got the part number for this ?

1A Auto Parts: @TheMan16111 This video should help you out. Here's a link to the blower motor resistors on our website for your truck.There seems to be a few different types that fit that vehicle. Hope this helps you out. 1aauto.com/1A/BlowerMotorResistor/GMC/Sierra1500/-/-/2003?utm_source=youtube&utm_medium=youtube&utm_campaign=1ATony

dentonfam: I have the same issue. Leads at resistor end of cable between resistor and blower control panel are fried (as are the leads in the resistor). Instead of soldering, how hard is it to run a new 7 cable between the blower control panel and the resistor? Anything pinching or holding that 7 cable wire in place behind the dash?

1A Auto Parts: You may want to check the blower motor resistor to see if it's acting up.

1A Auto Parts: You might be able to get a new knob from the dealer or salvage yard.

1A Auto Parts: @MrOldFunker You could use a test light to see if there's current going to an from those components.

1A Auto Parts: More than likely the blower motor resistor has gone bad. Usually that's why you start to loose the speed settings. 1aauto.com 888-844-3393

quadty11: Thank you! Just finished the job on my wife’s 03 Tahoe. The blower only worked on 5 “High” Not a hard job! Save your self some cash!

1A Auto Parts: It may be a bad blower motor resistor.

txrelichunter: How much is that little board?

1A Auto Parts: @txrelichunter Please use the link in the description and check our website, Thank You!

1A Auto Parts: HI Tucker, If you would like to call our sales staff we can help you out on the phone and match you up with the correct part. 1aauto.com 888-844-3393

Andrea Cash: The 3rd speed of the blower switch on my '06 GMC K1500 has not worked for a couple of months and last week it completely quit. I'm so glad that I googled "blower switch" and came upon your video before I wasted my small pension on a dealer only blower control switch. I'll now order the resistor and save your video for my husband's benefit. I might even install it myself. Thank you so much and have a great week! Andrea

1A Auto Parts: @caltex86 If you click on the link in the video, it will take you to the proper blower motor resistor.

dfri: 2006 GMC Sierra. #5 stopped working (might have been a fuse I guess, never checked). Now 1-4 stops working intermittently. I fiddle with where it plugs in, and 1-4 usually starts working again. Is the problem ever the plug itself that plugs into the resistor????

MrOldFunker: Nice video, my truck is a 05 gmc p/u is there a way to test resistor and fan motor because I'm not sure which one is on the fritz. Once fan would not work then came on now nada, zilch, nothin.

1A Auto Parts: @Toasty504 This is usually the problem if you fan does not work on all speeds. The trailblazer may be a little different in getting to the resistor and its' location.
