It has been awhile since I have been on here, but I am now having AC problems and I live in Houston. The AC was never really blowing cold, so I stopped at Autozone for an AC recharge 134A with stop leak. The pressure gauge was on the low side, so I recharged. The A/C is blowing less cold than before and with the transmission in Park, I am getting vibration with the A/C on. With the engine in Drive, the vibration appears to go away. Without digging into it, did I overcharge? Haynes lists R-134A equivalent.

Re: Air Conditioner
probably so. rent gauges from auto zone. -
Re: Air Conditioner
Did it vibrate before you added the refrigerant?
Before you added refrigerant, do you know if the compressor was working at all? Was it at least blowing cool air?2002 Silver Firebird A4<br />T-Tops, Leather, Y87, W68, Chrome Wheels<br />Bone StockComment

Re: Air Conditioner
Due to the lag in the system, I put too much refrigerant in the system. My low side pressure was about 100 psig. It should have been about 40 psig. Once I removed the refrigerant, the compressor quit vibrating. Not sure if it was liquid going across the compressor or compressor surge, but neither is highly recommended.Zaino; FireBatCave Decals; Red Inside<br /><br />K&N Filter & Lid; Removed MAF screen; FRA; Raised Air Box; 180°F Stat; BMR STB; 3\" Catco & S-pipe; Borla Cat-Back; O2 Sim; HPPIII; NGK TR55s; Taylor 8mm wires<br /><br /> <a href=\"http://www.cardomain.com/id/cbass300\" target=\"_blank\">http://www.cardomain.com/id/cbass300</a>Comment
