More Jetta AC Probs

Performance Kote on Thu September 18, 2008 7:18 PM User is offline

Year: 2001
Make: VW
Model: Jetta TDI
Engine Size: 1.9
Refrigerant Type: R134
Ambient Temp: 88
Pressure Low: 30
Pressure High: 210
Country of Origin: United States

Well, I replaced my compressor , expansion valve , and drier , vacked it down and charged with the called for amount of R134 and am getting 40 degree vent temps , however my compressor intermitently kicks off and temps come up for a few minutes until it kicks back on . I can sometimes get it to come on sooner by hitting the ac switch a couple of times . I pulled the connections to the Fan Control Module and everything looked good . Any ideas ? Also Vag Com showed no codes .

I would have replaced all of the pressure sensor/switches at the same time. On newer vehicles, I replace those, too. A fault sensor in the high side will do that.

With a variable displacement compressor I would be more concerned with proper charge level. Control valve has lead to more trouble than pressure switches. IS this a new Sanden compressor or another replacement brand?

Well , I ran the car with gauges on it while driving down the road and once moving and over 2500 rpm my high pressure drops to 100psi and the low pressure stays 25-30 psi . A buddy of mine related that it sounds like the condenser may be plugged . The temp on the inlet is too hot to touch and the outlet is slightly above room temp . Whatayathink ? I cant recall the brand , however I dont think it was a Sanden
