I have a 1983 300D Turbodiesel, that I bought 3 years ago. Last spring, I decided to repair the A/C on the car. There is a sticker in the engine compartment that at some point in the past, this car was converted to R134a.


• I replaced the climate control unit.
•* Then I took apart the A/C system and flushed it out according to instructions I found on PeachParts.
• From ********** I bought a new Behr R4 compressor, and new drier, new temperature sensor, new high low pressure switch, expansion valve (R12/R134a compliant), new o-rings. New oil compatible with R134a.


The system worked great for at least 1 summer and this second summer my wife drove the car, so I am a little unclear if the A/C worked this summer as well. However currently, the issue is the system is not working again.

I checked the pressure with a Manifold gauge set and it looks like the pressure on the low side is normal, but the High side reads nearly 0. I can hear the clutch engage on the A/C compressor. This all leads me to believe that my A/C compressor has failed after only 18 months (of course out of warranty.)

So my questions are:
•*Am I missing something? Could my compressor still be OK?
•*If I am going to replace this compressor again, is there someplace more reliable to purchase one. The one on ********** (Behr) looked great when I got it and was very affordable, $236, but if they are unreliable, whats the point.


Thanks
