I have been trying to solve an overheating issue on my '95 for a few weeks. I have been trying to evaluate the fan as far as if it is coming on at the right temperature and if it is running on high when the AC is on, etc.
I went to check for voltage from the harness connector with my meter and I notice that there is a connector between the fan and the harness
Is this supposed to be there? It looks like it is supposed to fit there but it is zip tied to keep it there and it just seems strange to me. It seems to be a straight through device, pin 1 on one side outputs to a corresponding pin 1 on the other side, and pin 2 to pin 2, pin 3 to pin 3.
I had no voltage ot the harness when the engine was hot and even though I did not have a thermometer to read the engine temp the radiator cap was reading above 220*. The fan should have been on and I should have gotten voltage at the harness. I turn the AC on to high and I get voltage at the Harness for the high speed fan.
I can't see how that extra piece could help if there is no voltage going to it or the fan so I took it out and plugged the harness direct into the fan. The fan works when the AC is on high but not if the car is hot an idling.
So do I put this thing back? Do I test it to see if I need to replace it?
