Is there a way to wire the AC switch to trigger a relay. What I want to do is use the AC sitch to turn on a relay to power two 80mm fans. Also would need to work when the AC is on recirculate, switch not pushed. The vehicle is a 2000 Chevy Cavalier. Thanks.

Test the switch wiring to see what happens when you turn on the switch. Is there a pos or neg output on one of the wires? If so that's your answer, if it's momentary check the relay section on this site to convert momentary to timed or get a latching relay. If there isn't go to the relay that drives either the compressor clutch or the relay that drives the cooling fans
