1994 Jeep Wrangler Q&A
1994 Jeep Wrangler Question: Ok I have an after market air con system it's a YJ model.
when i'm driving it work's great, but when i get to a red light or sitting still it short cycle's. it is charged properly, i had to replace my fan clutch, so i put in a heavy duty one, no luck. i put a shroud fsn in front of the condensing unit. no luck, had a bad tenpture switch, i replaced that. would just quit while driving, turn it off and back up and the air would work again. flushed the radiator put stright antifreeze in it, no luck.changed 2 hose's, I don't think it's the low side pressure vulve. i'm about ready to go nut's. finally i put it in a shop 2 day's ago, no it's driving their guy nut's, he has not been able to solve the problem yet either. Someone please HELP!!!! - airconn
Have them check the head pressure, possible flow restriction of Freon. Just a thought. - ProfessorG
Not enough air flow across the condenser coil while stopped.... spray cold water on the condenser ..... I bet the compressor keeps running then! ... One more thing, how much voltage at battery terminals with engine idling and accessories on? Also check compressor voltage! - pushrod
