Dear All,

I was out of town for two months. When I got back and started my car (it started up almost right away). She is a 2000 C280 with climate control. Anyway, I checked and the compressor is running. I could find the low port easily but could not locate the high port within 2 minutes so I could not measure the pressure, but the system does not seem to have lost the freon. Any ideas? Do these compressors have any internal relief valve that could be stuck? Where is the high port?

Thanks,

Greg
