Hi Sleepwalker, I have a 1995 S320 model. For some reason the A/C stop blowing cold air and I did checked for a few things, but couldn't figure out what sensor, sensor switch, or something else could cause the compressor stop working. There is no current going to the compressor.

I did check the following:

1. There is still enough freon in the system.
2. There is current at the pressure switch, the one that screw to the dryer.
3. There is current at the A/C off emergency sensor.
4. The fuse is fine.


Thank you very much for your help...
