One of the cooling fans on my 2002 camry 6-cy doesn't operate. Facing engine from front the right fan operates when the air is turned on, the left does not operate under any circumstances. I figure this to be the cause of several overheating episodes this past summer. With the cooler weather we're experiencing I don't seemed to have an issue. I still lose water from the raditor which I figure to be from not running with antifreeze and using regular water which evaporates?

I am supplying you with the wiring diagram and the way things are supposed to work so you can diagnose it.

I have a 1991 toyota camry that neither one of the fans on the radiator are working. The one on the drivers side we can get to run by direct wiring. The on on the passenger side we can't get to work at all. Do these fans have different names other than a radiator fan/

One should tune on with the A/C and the other is controlled by a sensor on the engine at the water outlet, there are 3 sensors there, not sure which one, but I do believe that if the fan sensor is unplugged with the ignition on the fan will turn on regardless of temp, check this out.

This could just be a relay issue however, if the A/C condenser fan does not work with power jumped to it then it is the motor that failed.

Here is a guide that will help with testing the relay:

I attached the wiring diagram below that will help with figuring this out plus another guide that goes into this.

Let us know what you find and we can go from there. Thanks
