The hi speed is controlled by the fan relay located in the under hood fuse block. It isn't working.

Call your local GMC Dealer and see if they have the climate control panel in stock. What happens is the circuit board on the back of the panel shorts out. The panel comes as an assembly and is very easy to replace. Don't go with a wrecking yard piece. I made that mistake once and it didn't work either. I got one from the Chevy dealer and it worked perfectly.

this problem is caused by a defective blower speed control resistor, it is located near the blower motor, very cheap to replace, part is around $35

Testimonial: "Thanks I thought it might be that. Good info!"
Yes,it is the blower resister,it controls all the speeds to the blower motor,it is located near the blower motor,and it might have a wire harness that is burned up too,replace it,and the wire harness,and the blower motor,the blower motor is what causes the resister to fail,it draws too many amps,even though it might sound good,and run fine,it is requiring to many amps to run it.If this was at all helpful,please rate,thank you.
