99 GS 300 AC gets too cold. In auto mode I have to keep the control temp between 80 and 83 degrees to be comfortable with outside temp at approx 90 degrees. The higher temp setting lowers the fan speed, but I think the compressor may be running all the time. I have the same problem in manual mode. Any suggestions on what might be causing this?

 

how's your gas mileage? if your gas mileage is really bad then the compressor is probably on all the time, but if it's not that bad then just leave it alone. most people have a problem with the ac not being cold enough.

 

i wish i had my ac too cold, with these hot temps we got, mines take a lil while to get cold

 

I have the some problem sometimes.

 

Send a little cool air to me. Mine is not cooling enough at 100 F

To test is the compressor is engage at all times put the air flow in low and open the hood and accelerate the motor for while. You have to notice when the clutch des-engage? (hear & see)
