After work today I decided to e-vac my a/c system and re-charge it. Recycled old r134A from system then drew a vacuum on it for 45 min. it held vacuum. Took off the vacuum pump and started to charge the system. Jumped the compressor to suck all the goodies in and it only excepted 4 oz of fluid. Took the jumper off to see if it would engage by its self. It did not. Where is the pressure switch on these cars and can I by pass it?
