Very important. LISTEN TO THIS... This Blower resistor is not grounded properly. Behind the air box is a bolt with 5 or 6 ground wires all hooked to this one bolt. Chevy didn't remove the paint, and there is no star washer there. After I replaced two resistors, I cleaned this ground, ...... No problem sense ... works great. ALSO behind the battery box is another ground, same thing with five wires to it, and this one is the ground for all the pass code stuff, after I fixed that, seems my colorado starts every time 2007... I found this from another brother on utube, and thought to pass it on .... tell me if it works for you. Stan from Hawaii
Glad I came across this video. One of our Chevy Colorado work trucks is having this exact issue. I too own a 2011 Colorado, but am having a different issue. The HVAC air inlet valve/door thing makes a knocking sound when it is in the closing position with the re-circulation button turned off. Not sure if the re-circulation switch has gone bad or if it's the HVAC Air Inlet door actuator that has gone bad. Any suggestions would be appreciated.
Hi I have a Chevy Colorado 2007 and I'm having problems with the ac/heater I put the air on and it flips to heat but the speed on 3 or 4 is not working can you help with that
How can you check whether the blower fan itself is good/no good? I mean, my first thought is to hook a positive/negative wire to it but is there a way to do that? It looks like a wire harness connects to it.@@Singleturbocobra
Hi i really need your help i noticed your harness cables are all black, mine are all gray, how do i know which one goes to red,yellow,orange and blue? Please
I believe the blower motor pulls to much amperage for the factory gauge wire.I feel if the connector wires were alot thicker they could handle more amperage
@@KM-oi9ks I put a buss bar mounted to the inner fender well and attached each wire individually. It's still best to replace the resistor and short harness for a complete job. I replaced the ground with the buss and it worked for awhile then worked only on high. I then got the harness and resistor kit and now it's fixed. This is a very prevalent problem on Canyons and Colorado's. Bad ground design as well as improper wire gauge. Typical GM cutting corners......again!
I’m not an expert but it sounds like with a lot of these trucks there are also grounding issues from a “splice pack” which for the hvac is by the air filter, under the hood near headlight on passenger side. If the ground is corroded it might be the source of the repeated burnouts? Again, I’m no expert, but look up your vehicle and “splice pack” and that might solve it.

I just bought a used Colorado with this exact problem, thanks so much for this !

Any suggestions on my issue I described?
Thank you so much for sharing. I’ll look in the comments if you mention where to get the components

I have a blower that doesn't work on any position. Should I still do what you explained in the video?
check the ground behind the air box, there is 5 wires hooked to one bolt.,, holding all these grounds. do this first.....Stan Hawaii
Where is the air box exactly? I’m having issues with the ac only working occasionally
How much did the replacements cost? Links?
Less than $20

@@Singleturbocobra Thank you!
Wow tnx for the tutorial very helpfull. So this will fit into a 2007 chevy colorado right?
@@luisavalos9535 yes
Thank you so much! The #3 never worked on my son’s truck. I looked at the harness and it was burnt out.
If it helps one person.Then it was all worth it 👍
check the ground, behind the air box.
What's the next thing to check if what you said doesn't work? I checked fuses and relays. My guess is it would be the blower itself.
Yes check the blower fan itself

Mine went Tan,Blue,Orange,yellow
Thank you for the video. Now I know I can can fix this! Weird question. Where did you find the aftermarket radio to fit this?
Find stereo and the harnesses on Crutchfield
It would help if you gave part number for wire harness for ordering.
The part number is from Dorman # 645-528 and can be found at your local autoparts store
@@Singleturbocobra thanks
how about the actual switch in the dashboard
Ok I just replaced this part a week ago and it's still not working correctly. All fab speeds come on but very weak. What's my next check to fix this?
Ground in the airbox...
Well, this worked for about a month until it smoked the connector again. What is the root cause and how do I address that?
I believe the blower motor pulls to much amperage for the factory gauge wire.I feel if the connector wires were alot thicker they could handle more amperage
Ground is effed up behind the airbox.

Is it the same problem if the ac only turns on when i slam my door?
I would definitely check it and see if it is burnt 👍
I cant remove the connector its too hard help!!
@gisellemendoza9025 I have seen them so bad before it melted together. I hope this is not what happened to yours
Thank you
@@ethanquesnel2319 Glad My video helped 👍
part number for wire harnees and relay

#3 doesn’t blow on mine. You got me wanting to replace the whole thing now.
Same thing on my truck
Mine did the same thing and then eventually 1 and 2 stopped as well. Go ahead and replace it when you can.
Same
Same #3...if it happens again - also check the ground behind the airbox.
Must be a weak part, Ive replaced mine twice on my 04.
Check ground behind air box. Mine same issue
It keeps happening to me . something is doing this .I changed it 4 time's?
