So recently my a/c stopped blowing. I checked the compressor and the condenser fan and both are working properly. I noticed that the blower motor was not working so before I considered pulling it to replace it I checked the fuses and relays, which were all still good. Then I pulled the quick connect wiring from the back of the blower switch and checked to make sure it was getting power and it doesn’t have a hot regardless if the truck is off or on. Any ideas on where to start looking to where that hot should be supplied from?

 

Should be able to find wiring diagrams for your truck here.

 

You could have a failed a/c control panel, the switch itself. There are some videos for checking potentiometers.
