I cant get anything to blow out of my vents. I tried putting a new switch in and still the same. I took the fan out of the dash and took it to autozone and they tested it and said it was still good. So I put it back in. I checked the fuse and it was not blown. What else can I check because it going to be getting hot pretty soon.
 
Blower/fan problem

You may have a faulty blower motor resistor. The assembly is mounted on the blower motor housing. The back side of the assembly contains a few resistor coils and a thermal limiter. It's likely one of these components has failed.

agreed. often times, the HCAV fan will only work on high - this is a tell tale of a bad resistor. i would start tracing power and see where you end up. good luck.
