I am wondering how test the 3 wire pressure (transducer) on a 1997 Cavalier's A/C .... A/C will not come on after a refill ... all fuses and relays are good ... pressure is good, system was vacuumed to -28 and refilled with oil and 134 .... i can jump the ground on the relay and compressor comes on and blows cold air
Any help would be great
Listening.....just literally came in here to post the same thing....thought it would be a easy 2 wire jumper.
After doing some reading....
DO NOT try and bypass the switch. It is not a switch persay in the sence of a 2 wire switch. It is tied back to the pcm and you can fry it. My gauge cluster started to flicker now......not sure if its a coincidence or I fried something trying lol.
