Owned this 2004 Colorado ext.cab 4X4 since new. * again * blower motor controller on A/C quit working on speeds 1,2,3 still works on "high" 4. this is the 3rd failure since new, and I've had to pay for repairs twice already. According to reports on internet problem is with resistor module that controls the speed of the blower. Spoke to two difference GM dealers, and he advised that the problem was with the module overheating and causing the plug to melt and cause the resistor pack to become inoperable. No warranty on part according to GM dealer. This is a manufacturer defect and safety hazard that could cause risk of fire, injury or death. This issue needs to be covered under a recall or some program to protect consumers from paying to repair the same defective part or system over and over again !

Colorado 2004-- the driver's window stops working and battery goes dead. The body control module is replaced. Then the fuse block has scorch marks. Possible fire. This is a common problem with a chev. Colorado. Repairs are being done by a local repair garage. Chevrolet has moved out of our area. There is some problem with the fuse block just waiting for a major fire or property damage to happen.

Blower fan works intermittently. Ocassional smell of burnt wires. Finally stopped working on settings 1,2 and 3, will only work on setting 4. this seems to be a common problem on the Chevy Colorados that GM will not acknowledge.

I noticed my floor was soaking wet after a long rain... I checked the windows and doors to make sure they were not left open...my truck leaks somewhere from within. My buddy said it is probably the firewall... now my truck smells like mildew and continues to leak, im afraid it might mold and cause me or my family to get sick. The windows always fog up as a result of the dampness, making it harder to see at night.
