Inadequate cooling

Hoverfly on Sat August 01, 2009 3:08 PM User is offline

Year: 2002
Make: Toyota
Model: Celica
Engine Size: 1.82zz
Refrigerant Type: 134a
Ambient Temp: 83
Pressure Low: 48
Pressure High: 175

My ac system in the past few years does not sufficiently cool during the few hot summer days in New England. I noticed that the compressor mag clutch does not cycle on and off at any time, just stays on all the the time. I replaced the TX valve on a recommendation to no avail. I checked the pressure switch, relays, both fans run and the sensor on the compressor as well. Where else should I look and what might be the issue?

Front of the condensor is nice and clean? With it running try spraying cool water over the condensor and see if it gets alot colder inside, it may help narrow down your problem.

The only thing happed is the fans went form high to low, as soon the water hit the condenser and the air coming out stayed at 60F. I cleaned it last year when I had it apart but did it again today. Can the compressor be tired for a car that is seven year old?
