Main breaker relay on a Toyota Tercel.
The main breaker relay continuity checked out good. So I have a new thermal fan switch, a new cooling fan relay, and checked continuity on main relay. What else could be causing this. There is not much to this circuit. I believe I'am lost for ideas at this point.

Did you test the new thermal switch? Are you sure you have no air in the cooling system (did you bleed the air out?).

In theory, you should be able to ground the wire going to the thermal switch and that should kick the fan on. This is what you had mentioned in the first post. It was the one thing I didn't do. So I did it and the fan would not come on with the ignition switch on. Then I decided to have the car started then do it. Well when I ground the terminal there is a noise that comes from under the air filter housing, around the carb area. Is there another mechanism that I'am missing here. So either way it did not turn on with that check. What does that tell us?
