- Colorado and Canyon fans - A plethora of knowledge dealing with all of the problems that I have had with my 2004 Colorado, especially with the blower motor having to be fixed every year. A small, 10 minute fix costing NOTHING can save Colorado owners hundreds if not thousands of dollars of dealer charges!

Third time for me! Last time got so hot it burnt my wiring harness and connector. I think it should fall in the safety recall category. If that was to heat up and catch fire with an infant or children in the car or anyone for that matter it could be very dangerous.

Real nasty when the temperature is 0 degrees and you have no fan for defroster or heat.

I have had this constant problem since I bought the truck. The blower will only work on high {level 4} or not at all. I have had this truck to the dealer 5 count them 5 times for the same exact problem. The 3rd time when I picked up my truck, I drove 3 blocks, guess what the blower quit working ! The dealer is full of all kinds of excuses, but no solutions. Oh and by the way the dealer is Gwatney Chevrolet in Jacksonville AR. I would highly recommend that you avoid this dealership & save yourself the aggravation.

This issue is exactally as discribed in other complaints. Looks as though there is no recall on this issue even though you can see that there is scorching at the plug which could've contributed to a fire. How many of you had to replace the battery at a low mileage?? I'm sure this had a bit to do with replacing the battery also. Let us all know if GM is taking care of this common problem that is definatly due to poor workmanship.

The blower knob for the air / heater stopped working on all speeds except high as vehicle was coming out of warranty,The dealer fixed the problem. a month later, air control knob stopped working a second tme. The second repair lasted just over a year, and has not worked since. Dealer stated additioanl repoairs would be at my expence. I finally gave up.

This is the second time I've had to repair this issue. Because the first time was over two years ago it was no longer under warranty. I can understand once, but twice???!!!! I love my truck and enjoy driving it, however if I didn't need my heater & air conditioner fan, I wouldn't get this fixed. Maybe Chevrolet should refund our money back when it is a repeat problem.

The fan in my 2004 Colorado was making a noise for over a year and the dealer basically said "oh well its a fan". Then, the fan would only work on high and after the dealer said it would cost well over $150 to fix - I looked and found parts and did myself - Over 2 hours poking around, but I fixed it.
I'll never by from GM again

After reading the other reviews I am extremely frustrated by this problem. I'm somewhat glad I haven't had it fixed, because it will just break again!
