A.C. blowing really weak

eharri00 · #1 07-21-2010, 12:05 PM

When I turn the vent on in my 1995 buick Park Avenue, it blows out very weak and blows from floor, vents, and window and it's very weak. Is it the A.C./Heater control assembly? I fully charged the A.C. and the lines in the engine are cold but the air in the car is really weak. You physically have to put your hand right up to the vent to feel anything. Any suggestions?

Is it the blower speed your having a problem with? Also, maybe the directional door actuators aren't working like they should?

It's the speed as well as it coming from the floor/vents/and windshield when I select vents. I thought it should be coming from the vents only. I just had the system charged and you can't feel it coming out of the vents unless your hand is right up to the vent. It's cool but not blowing strong at all.

do I need to replace the control unit or just the doors?

Your going to have to do some testing. I can give you vacuum wiring diagrams and electrical diagrams. Without testing, I don't know exactly what is wrong? My first thought is to check vacuum at all actuators, which means your going to have to get under the dash and do some testing.
