<<I removed it again and jumped #5&7 on the receptacle in the car and the clutch engaged fine and a/c worked. >>
Jumping 5/7 with relay out is simply bringing 12 v to the clutch, it does NOT mean the klima is bad..
You problem is the klima primary coil circuit [ that activates the contactor for the clutch] is not seeing a ground.
So, as Doc says, it can be in the controller..
However, your next step is to jumper the S31/1 switch at the
drier/reciever as the sig has to go there Before it goes to the controller. [ As Larry said]
**[ look at the schematic I sent you yesterday - see -s31/1]
If jumping that sw runs the clutch, it is open/or low on freon and is the prob..,
if it doesn't , is in the control/wiring..
