1999 Regal GS 3800 with Supercharger
I have never done this before. The AC in my '99 Buick Regal GS is blowing warm air so thought I'd try to do it myself and add Refrigerant.
I purchased A/C Pro made by STP that is R-134a. Just bought it and will read the directions then will work on it in the morning.
Any helpful tips would be much appreciated.
Thanks,
Garry

I did it on my '99 Pontiac Grand Prix GT. Find the low pressure line in your AC system lines, remove the cap (and don't misplace), and shake the refrigerant can. Make sure AC compressor is running, supplied line is connected to low preassure AC port, hold can so it's upside down, and empty it into the system. My Pontiac's AC system worked beautifully for the day and was blowing warm again the next day, meaning I had other issues needing to be dealt with first. Hopefully your experience is better as freon ain't cheap.
