Blower not working

This is a pretty common issue. The main reason a blower motor only works on high is because the blower motor resistor has failed. I would recommend replacing that part, and that should take care of your issue.

My blower motor only works on high speed. I have read elsewhere that it may be the electronic connection. Where is that located?

Heater problem
2004 Chevy Colorado Four Wheel Drive Automatic 22000 miles

You didn't have the 3.5 motor on the drop down that's what I got. My heater fan started out ticking when you run it on low, the other speed you didn't hear it. Now it has started doing it in the second speed to. Is it the fan motor if so how hard is it to change and where is? Thank you

The blower motor is on the passenger side under the dash. It may be something just rubbin against it.

I have a 2004 Chevy Colorado and the air condition started only blowing on high about a month ago settings 1 2 and 3 would blow intermittent at first than stopped blowing all together. Today it stopped blowing on high as well setting 4. What could be the problem. The AC compressor is coming on, but no air is blowing through the vents. Could this be a relay problem or a blower motor resistor malfuntion? Please advise.

Mike

It is a blower resistor. Here is a bulletin with part numbers. Subject: Blower Motor Inoperative In Any One or More Blower Speed

Models: 2004-2006 Chevrolet Colorado

2004-2006 GMC Canyon Blower motor inoperative in one or more blower speeds. This concern is due to a loose connection at the blower motor resistor.

Recommendation/Instructions:
Inspect the connection at the blower motor resistor. Replace the blower motor resistor and any terminals in the female part of the connector that show evidence of arching or corrosion. The replacement connector and terminals are listed below.

Part Number 15306069, Female Connector With Leads. Replace the connector body with leads only if the connector body shows signs of damage. It may be necessary to generate a SPAC case to obtain this connector with leads.
Part Number 12176387, Replacement Female Terminal. This terminal is made of copper-beryllium and can be located in Delphi tray 3 of your Packard kit. Only replace the terminal(s) if the connector body has no evidence of damage.
Replace the blower motor resistor only if it shows signs of arching or corrosion at its terminals.
Post back with the results.

The problem you describe could be the blower motor failing when the motor heats after initial operation. Also I have seen blower motor resistors that are pulling slightly high amperage cause a similar complaint.

There are four power settings for my AC, but only the fourth setting works. My AC works on full blast perfectly fine, but does not blow any air at all on the three lower settings.

I have a 04 rado with 65000 miles and myself and two fellow co works have all had this same problem with our trucks. Not to mention our Chevrolet work trucks all have had the resonator replaced along with the wire plug harness. The harness cost like 95 while the resonator only cost 35 Chevy should put a recall on this I have seen the exact same problem with 6 trucks that I know about
