Hello, I have a 2004 Chevy Colorado Inline 5 cylinder ext cab truck in which I am having complications with the air conditioning unit and also the rear drivers side white back up light. The air conditioner(not climate control) will always work on the highest setting(4), but will rarely work on the 3 other fan levels. There are times where settings 1-3 work, but it's only when the truck wants it to(it seems to have a mind of it's own), but the highest setting works 100% of the time. The second problem I am having is the rear drivers side white back up light which will not work at all. I replaced both bulbs and that did not solve the problem and now I am asking for your help to help me solve these problems without going to a costly dealership. I do not know if the fuses are bad or if there is something more serious that is wrong. The fuse #'s I have wrote down which could be the problem are:
Fuse #5 for the air conditioning control head
Fuse #26 for the back up lights
Fuse #29 for the drivers side rear tail lamp, and
Fuse #61 for the Back-Up lamps
I am no where close to being a mechanic and am in much needed help on solving these problems, so if anyone who owns a Colorado and has had similar problems are if you are a mechanic that could help me out I would greatly appreciate it.
Thank you very much for taking the time to read this.
Zack
