Car is stock,AC works fine once the car is moving for a bit (converted to 134a two years ago). Today, here in the DFW area it is 92 degrees and 67% Humidity. Car has been sitting out at Starbucks under a partly cloudy sky for 30 minutes. When i start the car and turn the air on luke warm air comes out (it's on MAX) when the car is moving it will slowly get colder and colder--all this takes several minutes and if I hit a stop light it will begin to put out not so cold air; as soon as I get moving again the air gets colder. It will take a full 7-9 mins to get the car cooled down assuming no more traffic lights. Once it gets cooled down it's fine--air is nice and cold--but--all this takes quite a while to happen.
In contrast, my 2001 Nissan pick up will throw out cold air the second you turn the engine on, no matter what the conditions are. I realize the 20 year old Buick will not do this but I seem to remember that GM had pretty good AC in 1987. Was it just the R12 that made the difference??? My question is this--what's it going to take to get cold air out of this AC at a stoplight on a hot day two munites after I turn the system on MAX???
The car runs at 180 w/ AC on--fan is running on high when AC is on. Has a 180 thermostat.
Any thoughts would be appreciated. By the time the car cools down i'm already home !!!
