I have an '86 buick century and my car overheats due to the fact that the electric radiator fan will not turn on. I have replaced the electric fan motor, the cooling fan relay and am in the process of replacing the temperature sensor on the engine block, but I cannot find it. Where would it be located? I also checked the fuse panel in the glove compartment and all fuses are good. What else could it be? If I cannot find the problem I will probably just wire the new motor to the battery and put a switch inside the car so I can turn it on and off myself. I would appreciate any input, thank you.
