Loss of fan - blower motor (hvac) high speed operation failure. With loss of high speed fan, other fan speeds (lower) operation became intermittent, works after jiggling blower motor wire bundle at connection point on blower motor resistor. Visual inspection shows melted wire harness connector at blower motor resistor, unable to separate (remove) the connector. Searched NHTSA odi database and found three very related defect complaints - inop fan, smoke and melted wires, fan loss. Fan failure could lead to fire from melted electrical connections, loss of visibility due to windshield icing in winter, fogging over when driving in changing weather. Windshield defroster requires operative fan and defroster is a required safety item. Dealer replaced blower motor electrical connector, wire harness, and fuse, charging parts to warranty and me for the labor. This appears to be a very common defect in this product line. There is a technical service bulletin for the repair including replacement of the connection wiring to insure any melted insulation is removed. This should be a safety recall. Dealer has old parts.
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.

Hvac system will hang up on defrost, it will not return to any other position until vehicle is restarted with switch in different position. Also when using vent on the higher fan settings you can hear and feel a surging of air the fan is not a producing a constant flow of air.
