2004 Chevy Colorado Blower Motor


Air Conditioning problem
2004 Chevy Colorado 6 cyl Two Wheel Drive Manual 77000 miles

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.


Do you
have the same problem?
