SOURCE: power door locks and drivers window have failed on 2004 colorado

I had the same problem to the T. I look online for all the same solutions and I can only tell you what worked for me. Actually what I think worked, HAHA! I went out to my truck and unplugged both battery terminals from battery and placed them together to supposedly reset the electrical system, "so I was told." After this for about 20 min or so, I went back out and in this order; re-installed positive terminal followed by negative terminal to battery. After this I checked locks and windows and surprise they worked. I've seen a lot of people say that all they did was wait and they worked later, so maybe it was that and not what I did, but who cares, they work now. Give it a shot and if it works for you, GREAT let me know, I HATE CHEVY CAUSE OF THIS......they wanted me to pay for a stupid diagnostic before they would help me........well screw you I fixed myself. LATER

SOURCE: blower only works on 4,123 not working.

Hi There;
You say your heater fan only works on high.

This issue can be repaired by replacing what is called the "blower motor resistor". The electrical current flows through this unit in all positions except #4.
If you look under the dash on the passenger side with the heater fan on #4 you will hear the blower motor running. Just slightly toward the drivers side of the blower motor & closer to the firewall you will see a four wire connector. this is attached to the "blower motor resistor". If you get a replacement one & examine it you will see two screw holes where you will need to remove the 9/32nds screws from the one in your truck to remove the fauly one & install your new on. This part is relitivly inexpensive & it is not worth trying to locate a used one.
Please let me know if you need more info on this

SOURCE: 2005 Chevy colorado blower motor only work on

The blower only works on High because something called a "blower motor resister" has gone bad. The resister works by resisting/absorbing the power to the blower motor on the lower speeds, At high speed it lets all the power go through. The part is about $20.00 for a Jeep (common problem). Getting at it and knowing where it is I can't help. But with that knowledge, you should not get screwed by the repair shop.

I have a chevy colorado truck and the air is cold when it works and it would only work if it was turned up on 4 1-3 didnt work and now it want come on in 4 what could my problem be

I have a 2004 Colorado since it was new. There was a recal for the blower motor problem. I think it was for a defective connector to the blower resistor assembly. There is also a recall for a bad brake light switch. I would take your truck to the dealer and get this recall work done.

On low speed there is a ticking in the fan as though something was rubbing. The noise goes away on higher speeds. How can I remove the heater motor to see if there is something rubbing. This is on a 2005...

It's on the pasenger side of the truck. Where the persons feet would be if sitting there. Lay down on your back and look up under the dash. There will be you blower motor. There are three gold or siver colored 5.5mm headed bolts holding it up to the heater case. Pull those out and the blower motor will drop down. Also you will need to remove the electrical connector before pulling the screws out. I will bet a peice of paper has been sucked out of you glove box and is in the blower motor. Be sure to note the position of the blower motor, it can only go in one way.

Blower on my 2004 Chev Colorado only works on high setting #4.

You need a resistor pack, which is likely located in the air box, near the blower motor.
