Replace the blower motor resistor. It is right there with the blower.

SOURCE: 2005 chevy colorado runs rough and gets bad gas mileage.

Sounds like it needs spark plugs and wires, and a fuel system treatment.

SOURCE: heater fan switch only works on 4. nothing on 1-2 or 3

Most likely the blower motor resistor has failed. GM offers an updated version.

SOURCE: 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.

2005 Chevy Colorado LS 5.3L Blower motor iOS not working. Replaced the resistor because that was burnt out but it didn’t fix the issue. Figured out the connector only gets power at the brown wire and...


The top wire at blower motor is voltage, the bottom wire is ground. So brown wire is voltage, orange wire is ground. So, the resistors, havc control, on and off and speeds are controlled on the ground circuit. Generally if ground is good, no voltage or very little on the ground circuit, because the component is using the voltage. The wire connector for your blower motor is it any good? You could remove blower motor, use jumper wires off battery for voltage and ground, the blower motor should run up a storm. It wouldn't hurt to use inline fuse, just incase.
I looked at info for 3.5L, my info didn't show 5.3L?

    2005 Chevy colorado blower motor only work on high.


    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.

    Fan blower only works on high speed (4) not on any lower speeds


    this is caused by the blower resistor as you correctly diagnosed, but the new resistor is blown because the fan motor is drawing to much current and blowing the resistor back out, replace the blower motor and resistor again.

    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
    Farrout!
