Default 92 blazer wiring problem

Howdy all: I have a 92' 1500 Blazer that I bought. It has a AC/heater blower problem. It was working on High blower only. I can hear the relay clicking but no fan except on High. Yesterday, the blower stopped working altogether. there is no power at the fan. Does someone have a wiring diagram or can tell me what wires control the fan from the control head? I ordered a new resistor and will put that in as soon as I get it. Thanks for any help you all can give.

Howdy: If nobody has a wiring diagram that shows the AC/heater control, can someone tell me where to find one? Helm Publications does not make any manuals for the 92' anymore and Chilton (sucks) does not show it in their manual either. Tom

You could check eBay... There are currently 4 1992 C/K Wiring Manuals on eBay right now ranging from $30 +s&h to $50 +s&h.

The schematic for your truck is attached below. If only high works, the blower motor resistor pack is likely shot. It controls the low & medium fan speeds.
