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?

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?
