brewtoo is correct on the fan operation..


IF you select Defrost OR the "demist" button on the pushbutton unit the ground signal should be at the low pressure switch.....IF not then 1 or 3 possibilities exist.

1) the evaporator temp sensor is bad

2) the blue 2 pole temp sensor is bad

3) the pushbutton control unit is defective

The K9 relay is in the fuse box..has a painted black top..located just behind the fuses in the middle.
