Default 1993 Camry radiator fans inop

I have a 1993 Toyota Camry that overheats at idle due to the radiator
fans not coming on. A friend checked and says the fans are not geting
power to them. Could it be one of the relays on the side wall ? Is
there something else that is a more common problem. I put in new water
pump, thermastat, and timing belt. Water pump was needed ( old one
bearing going out. But the fans are not engaging with or without AC
on.
And my friend said I do not seem to be getting power to the fans.

There should be a fuse or resetable breaker, but if it overheats just
idiling around that does not seem right, how hot is it out, is your
radiator clogged , is air in the system, you are sure its full.

============================
Try unplugging the wires to the temperature sensor in the lower
radiator tank.
The default should be to run the fans continuously.
If they turn on, you've found the problem.

I unplugged wires to temp sensor and the fans still did not engage.

Could it be one of the relays on the side wall is bad ?

You should first verify that the fan motors work by applying power
directly. I wouldn't be surprised if the brushes in the motor are
already worn out after all these years. Just becareful the pos jumper
wire doesn't short to ground or a lot of current is going to flow
through the wire.

BTW, does the AC fan come on when you operate the AC?

www.autozone.com has an online free repair guide for your reference. It
explains relay operation but doesn't give detailed connector
assignments so you'll have to refer to a Haynes repair manual at your
local auto parts store.

With my '96, if you turn on the AC, and the engine temp is normal, both fans
come on at reduced speed, then as the radiator temp increases due the hot
condensor, they both go to full speed for a minute then drop back to low
speed.. If the AC is off, and the engine temp is normal, both fans stop
until the radiator heats up a bit then the radiator fan only comes on at
full speed. Is this how yours works, Daniel?
