Truck keeps blowing the relay fuse under the hood for the HVAC system on the truck. The fuses inside the door for the HVAC are not blowing though. I have no heat or air conditioning because of it. Not sure what to do?

Disconne your blower fan and check the resistance of the motor and see if it is shorted. Also check the blower motor resistor and see if it is burnt. This is a common problem in gm's
