Question about 1979 Pontiac Firebird
I checked some old diagrams for that and though they show just about everything else, the a/c part is vague...If I remember correctly, I believe the compressor gets powered through the heater control switch, to the heater relay, then to a thermal limiter switch (a small black item with two male spade connectors protruding from it.) then that side goes to the clutch terminal. The other clutch terminal is ground. Since a/c was not a "fixed" option back then, likely there is a separate diagram for that option. Hope you find a diagram, but I believe I have it right. or, darn close to it! The only ting I can't remember is where the heater relay draws power from (likely a fusable link connected to the starter battery terminal)
