car came to me with a/c inop. we charged and checked, system pressures were very high, compressor would cut in and out. technician assumed this was due to compressor itself. we replaced compressor, drier, switches, including evap temp switch and engine temp switch, and expansion valve. compressor pressures look better now, but the compressor does not want to stay running. i have gotten involved with this since customer is now into this over $1500 and still has no compressor operation. the auxilliary fans are not operating. if i disconnect connectors on blue switch in the front of intake, the fans do come on. i can bridge them to get the fans to come on low speed. i cannot locate a wiring diagram specific to this vehicle. the mercedes dealership across the street is secretly looking to see if they have the diagnostic box to check system. any help is appreciated (my compressor is a nippendenso reman from german auto parts in atlanta.
thanks,
