Hi everyone. I am having issues with engine cooling on my 95 EVC. I had no lower speed fans operation and no after run fan operation or coolant pump. I checked both resistors and they are good and I have both fan speed operation when I jump the gray, upper radiator temp sensor. I just replaced the 4 pin lower, blue sensor and got low speed fans at lowered engine temps and then high speed fans with high engine temps but the speed never reduces after the engine cooled while running. Additionally, when I turned the engine off when really hot, and removed the key, the fan operation stopped and there was no after run pump function. Whe the key was replaced at quarter turn, high speed fans and pump came on. Any suggestions on where to turn at this point would be much appreciated. TIA, Sean
