I have a little problem with the radiator fans kicking on. Here is the deal. I jumped the wires to the fans to make sure they work. I tested the relay to make sure it works. The fans kick on when the motor gets warm, & sometimes they don't. My temperature sensor on the block is ok too. The thermostat is new, but I'm yanking it out till winter.
I'm not at work & don't have access to Mitchell program at the moment. Has anyone had to replace the temperature switch on the bottom of the radiator? Anyone had similar problems with the fans kicking on when they want? How much does the ECU play on everything working right? I'm looking at this mouse wiring diagram in my manuals. Trying to narrow the issue to what it could be.
