Ac compressor relay

Asked by MWest83 May 26, 2018 at 11:46 AM about the 1991 Buick LeSabre Custom Sedan FWD

Question type: Maintenance & Repair

I have a 91 Buick lasabre and my compressor won't
stay on to retro fit and charge. I was told I could
bypass the relay to make it stay on so I could
charge it with refrigerants, but all the relays are in
different places in the car and don't know which is
the right one... Could someone PLEASE show me
the right one? I live in St. Louis, Mo and its not even
summer yet and its sweltering already...PLEASE
HELP!

Unplug hi / low switch from A.C accumulator put a jump wire into plug side this will allow the compressor clutch to in cage to put in freon once freon is installed remove jump wire and plug back into accumulator.
