1986 300SDL. Problem: when accelerating quickly (not full throttle) or cruising at speeds greater then 50 MPH, I believe A/C RPM sender is causing A/C relay to shut off the compressor.

Possible Fix?: I understand there is a way to by-pass the compressor's RPM sender to the A/C relay.

Diagnosing and R&R performed: replaced Climate control unit (reman), Compressor Cut-out Circuit test (normal values).

Thanks for your help.
