2004 Chevy trailblazer air conditioner does not work on speeds 1-4, speed 5 works just fine
2004 Chevy trailblazer LS, air conditioner does not work on speeds 1-4,
speed 5 works just fine, when I turn speed 1-4 the warning brake light
comes on and dings, I just bought and changed the blower motor resister
and its still the same 1-4 doesn't work, what else could it be ??? I even
pulled the 2 fuses for the air conditioning to reset the system,I have been
reading all the air conditioning problems and it all comes down to the blower
motor resister but there must be another solution,
