[attachment=5807][attachment=5807]I have coach1518 with the cummins 600 engine.  I added freon and slugged the compressor and need to replace it.  Does anyone know the model number for the Sanden compressor for this engine?   Any suggestions appreciated.  We are in Houston Texas.

My dash air became inop because of a plugged thermostatic expansion valve. Classic symptoms were very low suction pressure and very high high side pressures with no cooling. Simple diagnosis but not so simple of a fix.

First challenge is to remove the old TXV. In my 99 it is in the bowels of the lower dash area. I finally gained limited access by removing both the HWH control panel and the rear view monitor. After evacuating the system, don't snigger I have a reclaim unit, I removed the TXV.
