I have a GMC Sierra 1500 4 wd extended cab pickup. My blower motors were working fine. I shut them down when I parked the truck. I left again approx. 10 min. later, and there was no air blowing when I turned them on. I have checked all the fuses I can find, fuse block under hood and in the truck. cant tell which relays are to what under the dash, as my over the counter chiltons has no really good diagrams etc. I tried to find a expanded schematic to no avail. I have had not much luck getting to view any pictures etc of the heater, A/C blower circuits. Can anyone help out with info on similar problems, or with a good schematic, and maybe some pictures too?
