When idling, my radiator fan won't come on and car starts to overheat.  all fuses are good, and I'm getting power to my fan.  Do I need to change my fan or is something else I need to check?

The next step is to check the fan motor with an ohm meter. It should show a very low resistance. I also have some jumper wires I use to put battery power directly to the fan as an alternative check.

it might be the thermostat, it could be malfunctioning so you might wanna check it


check for a ground for the fan, just put a test light, or voltmeter between the neg post of the fan plug and the battery and check for power, if that checks out its pretty certain that you need a new fan. fans are pretty cheap if you buy used and they tend to be quite reliable so used isnt too bad of a way to go


I unplugged the fan swtich located on the thermostat housing, jumped the wires over and the fan turned on. So, I installed a new fan switch. my fan now turns on it should. Thanks you for the help
