I have Chrysler Concorde 1996. Air conditioner is nor working. When checked the system I found out that clutch is not working. I replaced the air conditioner relay. I took the realay out and checked the voltage at the coil pins. It is OK 12 Volts, but when the relay is placed back at its placed, the voltage disapperas. When I short the pins that feed the clutch , the conditioner is working fine. It seems that the problem is in some kind of sensors that control voltage for the relay, but I don't know where they are and how the current goes to relay. Does any one know where they are or have an elecrical scheme of the system with all sensors and relay connectors?

Thanks in advance.

P>S. Self diagnostic at Automatic Temperature Control shows no errors.
