I believe that the coolant sensor for the ACC is in a dual element sensor on the engine - one set of pins for the ACC, the other for the idle control. The AC on my SDL would turn off the compressor as soon as the coolant hit 80C - the PO had reversed the sets of wires on that sensor. The AC worked great after I switched those two plugs.
