mbdoc, thanks for the feedback. Will check this weekend.
IF wiring at compressor electrial plug, broken or poorly soldered wires checks OK
I will move to the other end - check at ECU (although I doubt this end has problems)
Then I will move back to CCU and check my soldered points.

The fact that no Klima relay exists on this car shortens my options.

What would be the next step?
