A/c Refrigerant Hose
#1
Hi, My 99 Buick regal LS does not blow cold air when i turn on the a/c. My suspection is that the refrigerant (R134a) is low and i want to fill it.
I am not sure what is the pressure i need to fill it. If anyone knows the correct pressure do let mw know and also the hose where i need to connect the can. There are 2 locations under the hood one is in the center near the windshiled and the other is located near to the driver side.
it would be great help if anyone knows the pressure.

The low side is the one in the middle near the firewall. That would be the one you would want to use. Check your AC hose that has the high side pressure port on it by the air filter. Some Regals had problems with that hose rubbing on the side of the tranmission and rubbing a hole through it. If it has a hole in it don't bother tring to charge it without fixing the hose. I would also recomend have the air sucked out or the system evacuated before charging it back up.
