ive read almost every single thread from benzworld to 190revolution. can someone please help me? does anyone have any tips on how to make the a/c in a 1990 190E 2.6L cooler? i mean really, super ice cold! i live in palm springs, the temp gets up to +120 degrees it cools off at night (around 10:30pm) to about +90 degrees, which is still effing hot! everything on my car is in top shape, my compressor and receiver dryer were both replaced in april 2008, heater valve is working fine, no vacuum leaks either. its just that my car is so GD hot! especially at idle the air feels like its blowing out at 80 degrees from the a/c. i get mild relief if im driving at 50-60 mph, but even then its not really that cold? what can be wrong? everything is working fine. if it was ....say 85 degrees here then the a/c would feel fine or if it was in the 70's then it would even be fine at idle. what gives? anyone have anything helpful to add...other than telling me to buy another car or move out of palm springs? thanks and cheers!
