A/C and relays
Trying to fix the A/C in my car
1991 Camaro RS 3.1l
Problem:
When I turn on the A/C my radiator fan does not engage.
I've installed a new a/c and heating control unit (the box with the switches for the temperature control and the blower fan control).
I've found three relays on the firewall, and I have ran their numbers through my works computer. They all three come back as "a/c relays" but I am fairly sure that one is specifically for controlling the fan. Can someone tell me which relay should be the one controlling the fan?
Thanks!
