shane bond: I have a 99 suburban, replaced the resistor and still nothing ! Took the
fan out and hooked it directly to the battery and it works ! Put it back in
so now where do I check ?
Matt D: Another well explained video on this model truck! Thanks 1Aauto!! You have
help me learn and do so much on my truck vs other videos where I'd be
guessing much more lol
FrankieNY59: All my speeds work except 4. 2001 Yukon. Do you suppose it's the same
Sacha Parris: OK HERE GOES I HAVE A 2002 CHEVY SUBURBAN 1500 5.3L and at first i baught a
new blower motor since mine was making all kind of noise , so i replace
that one , then when i had put it in it was only working on 5th speed so i
knew it was the resistor , so baught i spaking new one and add it to my new
blower , now i notice it works on 1 2 3 4 but on the 5th its shut my
heating systeme completly off > WTF IS IT NOW LOL PLEASE HELP ! CHEERS
I have a 2000 Silverado 1500. I just replaced the resistor because the
motor only worked on High. Immediately after replacing the resistor, it
started blowing cold air and only worked on defrost/floor setting. The
controls weren't changing anything and they worked fine prior to the new
resistor. Is it the control module? Could the blend door actuator and HVAC
mode actuator have gone bad at the same time? Any ideas are helpful! I just
had to drive 30 mins at -20 temperatures!
mic88ed: thank you sir !!!
JoshWalkerMedia: Ok so i have having a problem with my truck a 99 chevy silver ado when i
turn the blower on ac or heat it vibrates a lot what would cause this?
victor1964ish: Hello, I have a 2006 GMC sierra. Currently all levels of heat work however
when warmed up there is an Oder like some wire burning. At
times when I listen closely I hear the levels on the blower go weak. Could
this be the resister or the blower motor?
ahill7866: Thanks for the video, helped me out perfectly.
humourcar: Your videos are extremely helpful. Thank you for all your hard work.
ELAINE WALKER: What causes our AC in our 2004 Chevrolet Silverado to work when we first
start our truck and then quit working after we drive for a few minutes,
then start working 15 or 20 minutes later and continues working and not
working. Could that be related to this blower resistor?
Larry Szczepanik: best demo so far ty
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).
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?
Harlan Reymont: Thanks for the great videos! I have an 04 Yukon SLT with dual front plus
rear automatic climate control. Recently the front passenger side stopped
pushing air in both heat and cooling modes. I was actualy driving the
vehicle when it stopped working and I heard what sound like something
ground to a stop. Rear and drivers side still work fine. I suspect a door
actuator, what are your thoughts?
Thank you for your time!
QQTrick1QQ: Thanks for the video, I think you could make a career under the dash on
the passenger side.
If you had put the resistor in 180 degrees the plug would of fit?
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
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
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!
Jacob Order: I have multiple problems with my heading system. Only the highest speed
will work on the fan. And the heat on the driver side setting is either the
hottest or cold. I have an 04 silverado
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.
22matthewlewis: just wondering if you knew if the back blows air and the front dose not
would it still be the blower motor resister?
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
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.
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
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
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
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
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.
