aaimmorl Posted May 10, 2004 Share Posted May 10, 2004 I'm trying to recharge the R134A in my Lexus. However, when I connect a can to the low side of the system and put the AC "on", the compressor only stays on for several seconds before turning off. Thus, I can't get any refridgerant into the system. I was told that there is a low charge cutout switch somewhere. I pulled the connector off of the receiver/dryer and shorted out the contacts, but the compressor still cuts off. Can anyone help out?

LEXIE Posted May 11, 2004 Share Posted May 11, 2004 connect your refrig can to the low side fitting and submerse the can in very hot water..say 150F. this will drive the refrigerant into the system and raise the pressure above the low cut-off point and allow the compresor to kick in. did you lose all your refrigeratnt thru a leak or are you recharging to and empty system after a repair?? lx Quote Link to comment Share on other sites More sharing options...
aaimmorl Posted May 11, 2004 Author Share Posted May 11, 2004 thanks for your input. I did put the can on the exhaust manifold to heat it up, but that did not seem to help. maybe I should try a fresh can. anyway, do you know where is cutout switch is so I can disable it?
