ok - i went thru this same issue last summer. The problem is a poorly designed electrical connector between the blower motor resistor board and the wiring harness.
All of these things can be assessed without taking the dashboard apart.
Find the blower motor resistor and remove it to make sure that the resistor is not fried, if it is you can get one a NAPA for $20. If it isn't then just look at the female and male ends of the connection and check to see if it has been burned up. If so replace harness, if not all you have to do to get the intermediate fan positions to work is to take a small screwdriver and slightly bend the "male" connectors so that they better contact inside of the female end of this connection. Very easy and cheap
if you need more info let me know

hi i was wondering if you would be able to tell me where the resistor is located?

it is located under the dash on the passenger side.
look for the blower motor and it is part of that assembly area
there are two bolts holding the resister block into the assembly
look for the connector ( white in color )
good luck --- i hope this helps

I have a 04 colorado, the ac compressor cycles on and off. I took it to the dealer, they said it had a bad schrader value, and low on refrigerant. $260 later it still acted the same. Took it back, they said they got a bulletin from GM. saying there is a sensor behind the dash that is bad. $841 later it still acts the same, they said it is to cold out now so it is going to cycle on and off.

Sure you're all set by now, but others may need the answer and I have it. The plastic clip that holds the cable head to the switch housing is weak and poorly designed, causing it separate from the housing when pressure is applied. The more it happens, the easier it comes out, as the prongs wear. I fixed mine by taking the bezzle off, removing the switch housing and clicking the cable head back in. Then I wrapped a solid, 16 gauge wire around the two prongs that the cable head clips into so that they could no longer separate and let the cable head slip out. Been fine for 3 years now. It used to happen a few times per month. Another bullseye from the GMC engineering department.

hey, read your message iam having the same problem,i just bought a new resistor yesterday installed it and nothing happened no fuses blown,but the connection looks fried female end,so iam going to try your solution to see if it works,if not i may just get rid of the truck i have had all the problems with this truck that people have listed on this site and i mean all of them!. thanks for the info.

hi,went through the removal of my blower fan last year it seized up,its pretty simple except for one screw,there are 4 small 1/4 inch screws holding the blower on,if you look up under the dash on passengers side you will see the blower(extreme right side)look for the screws and remove them there is the above mentioned screw in the far right corner against the floorboard/firewall its hard to get to i pulled my carpet down it helps some,make sure to unplug the electrical connection and it will come right out you should be able to remove your leaf,i did not reinstall the hard to get to screw mine works fine! good luck.

I have had that harness replaced or spliced and taped more than you could imagine, I had no air as much as I ever had air that worked. Several times we could smell the wiring burning before it went to working only on high on my 04 colorado and they are just now recalling it within the next few months. My mechanic called and they said the replacement harness is out and you should qualify for a refund if you don't want to wait, fix it now. It is nice after all this time!
#19 of 19 Heater Control Cable Problem
Jan 02, 2012 (7:21 pm)
I'm having a problem similar to capfsu had. Had the clicking noise, but kept trying the knob. I guess I twisted it a bit too much and a piece of plastic on the back snapped. I had to replace the whole system, but now, after I hooked up the heating control cable, the knob on the new one will only turn so much. I get resistance at a certain point when going towards a warmer temperature and if I keep pushing, the retaining clip will pop out, meaning I have to pull the whole panel off again and reattach the clip. So now the wire will only go in so far and the temperature will only get so warm (not warm enough sometimes!).
Is there anything I can do to this wire to get it to push further in, like it should? I'm pretty sick of all these Colorado problems. Have this issue, the blower issue, and now the valves on the head are going bad and I'm past warranty...
Thanks for the help on the wire.
