1994 Pontiac Grand Prix SE 3.1L system VIN: 1G2WJ52M9R
The grand prix is fixed. Thank you to all who replied.It was a 134 system.The clue that I ignored was the gauges. It is basic ac mechanics that when high and low sides are the same or nearly the same the compressor is faulty. In this case we had replaced the c...
