The AC works great but I only have one fan speed no matter where the switch is located. I remember on my old J10 Jeep that it had a resister plate or something like that that I had to replace to get the multiple fan speed to work correctly. Does the GMC use the same system? If so where is it and what do I ask for to get a new one?
The PO had put in a manual water valve in the heater hose to shut off coolant to the heater. Seems the heat is on all the time unless the valve is closed. I would like it to work correctly. Again, I assume there is a water control valve for the heater that works off a cable to the dash controls. Are these valves still available? I am going to spend some time lubing pivot points and cables but I think the PO had used the water valve technique for so long that the original heater valve will never recover.
Thoughts from the list? No sense me fussing for hours if someone has devised a simple fix.
