The connector that plugs into the blower motor under the glove box became too hot and melted the plastic resulting in the a/c and heat not to work (this includes the windshield defroster). I've been looking up problems and solutions and found that this is a recurring problem with GMC and chevy trucks yet there has not been any recall, in fact the dealerships have an extremely overpriced kit to fix their faulty wiring. About 66,000 mi.

Fuel Injector Control Module for one. Crank sensors,
fuel rail pressure sensor , engine computer (ECM) and you should have a professional grade scan tool to work on these vehicles . You could look on YouTube, there are a lot of guys that post auto repair videos there, even ones on diesel's with no start problems.
Odometer dims and goes out. it does this randomly
Usually when this happens you will have a loose contact (earth wire) and it may be hard to find. Try removing the lower cover around the steering column and, with lights on, reach up behind the instrument cluster and wiggle the wires.
