HEY EVERYONE I GOT 2000 CAVALIER PROBLEM NO HEAT AT ALL NEW MOTOR AND RESISTER TRY HVAC UNIT ALL FUSES GOOD AND CANT GET IT TO WORK PLEASE SOMEHELP ME LOL
you mean the blower motor isnt running?
try pulling the blower motor out, and see if it runs when hooked up to the car, but out of its holder.
I have seen debris stop the blower from working before.
If it doesnt, unplug it and bench test it to make sure it is good.
