how the hell do you fill the air conditioner in the 94 burb when the compressor wont kick on? years ago you could trick the compressor into comeing on when it was low on freon by unpluging the plug on the accumulater and jump a wire between the twp plug terminals and the compressor would kick on and suck the freon out of the can.
is that still possible or do you have to take the dam thing to the shop just to fill it when the compressor is empty.
