Chevrolet Avalanche Fuse Problem
check yoru fuses first, then if you have a test light, test to see if resistor an drelay are getting power, they are by the blower. one or both cold be bad or the control unit may be bad. you also might try takeing the fuse out and putting back in after a minute or so. otherwise you'll need to have it scanned to see what 's wrong.
