Question about 2001 GMC Yukon XL
2001 Yukon rear Hvac works fine, front is dead, 30amp fuse in engine compartment is blown, replaced w/ another 30 amp fuse and as soon as I switch it on, that one burns out too. Not sure what to check next.
Could be a bad ignition switch.. needs to be checked by a professional.

Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.

Are you aware of any codes that may stored in the body control module and do you hear a clicking or ticking noise in the rear?
