I have the truck listed above Southern Comfort and my air turns on and off but it wont blow. It will blow the air from you driving but nothing when you stop.

Good morning,

I attached a diagram for you to view. You need to verify powers to the blower motor to see if it has power. I highlighted the wires to check.

Check the 40 amp fuse in the fuse box listed.
