2005 Chevrolet Silverado A/C problems
 

I have a 05 Chevrolet Silverado 1500. About a year ago the a/c blower controls 1-5 started going out so I changed the blower motor resister. It worked fine for a while then a few weeks ago the driver side started blowing heat so I changed the actuator. It worked fine for about a day now it wont blow anything. Not sure what the problem is now, any ideas??

check the connector into the blower motor. its probably all melted like a grilled cheese sandwich.

if the connector is ok, turn the speed control to high and hammer fist the blower motor. if its starts working, you need a blower motor
