    my chevy 1500 blower fan has been failing for years, speeds 1 and 2 failed and now speed 5 failed about a month ago. Now today none of the speeds work yet there is heat when I drive since I can feel it coming out of the vents.

    just a thought i have seen alot with the blower motor wiring shorting out, gm has a update harness, look under pass side dash unplug wiring to blower motor and see if it is melted, mine shorted out with only 10,000 miles on it
