Problem for Volkswagen 1999 Passat

I have a 1999 Volkswagon Passat. The air

By go_nra_2007 on Aug 03, 2009

I have a 1999 Volkswagon Passat. The air conditioner works great at night or when the outside air temp is below 80°; it will put out 55° air. But during the day it will only put out 10° below the outside air temp. The freon level is correct, the evap and cond fan runs great. The evap area is clean. What do I check now?

Try to straighten the fins on the condenser. R134a systems do not operate efficiently during idle(because of the condenser) not being able to exchange the air.

check to see if you have a cabin air filter and if it is dirty have it replaced at a local auto shop.. if that isnt the problem and the freon level is correct then you will have to live with it.. a/c are concidered effiectient if they cool 20* below ambiant tempature.. personally i would say have the freon level/quality checked again
