2002 GMC Envoy SLE, 4.2 Liter I6, 4WD, 160,000 Miles
Seems that the blower switch on the dash is slowing losing the ability to work, at first position 2 stopped and the progressively 1, 2, 3 and 5 no longer work with only position number 4 currently blowing anything out.
Everything else works just fine, the temp slides turn the heat up or down on both sides and I have no problem switching where the air is coming out be it the floor, mid level blend or the defrost. Thought maybe it was the switch?
Might anyone have a thought as to the reason and solution or repair.
In reading thru the other ENVOY posts it looks like it may be the blower motor resistor assembly or module.
I would appreciate any help, instruction and part number, thanks

The relay/resistor is up behind the glove box on the blower case, also watch for the connector having melted, this is a common issue on these trucks.
