A/C condensor fan and radiator fan stay on - Toyota Nation Forum : Toyota Car and Truck Forums

I recently replaced a few parts of my 91 camry v6 (timing belt, water pump, ignition wires, dist. cap), and now both a/c condensor fan and radiator fan spin once I turn the key to 'on' position, fan relays and gauge temp sensor seem to be fine, what may have caused the problem?

most likely a faulty temperature sensor of sorts.

This is what generally happens when the a/c pressure sensor is not well plugged in. Besides your receiver dryer there is a plug that needs to be well in (small black plug with 2 wires.
What you can do is unplug it, jump both connections together and fans "should" stop working. Try that way first.

Could you give me more detail about the location of the A/C sensor and receiver/dryer? I don't have a service manual.

If I remember well it is on the receiver dryer itself (or then very very close to it). The receiver dryer looks like a small metallic bottle and is located near your battery, right of your a/c radiator (condensor).

Well in fact according to your model I am not 100% sure it is on the battery side, perhaps it is just on the other side (still on the front and near the radiator) but you can't miss it, it's like a metallic bottle

I could not find it near the condensor, my condensor fan is at left side. Can someone who owns this model give me some clue?

here is apic of a receiver dryer, yours isn't the same but at least it can give you an idea of what it looks like. The pressure sensor is for sure on it...

Thanks a lot, Nico. I found the A/C receiver, it was by the right side under the battery. There were two blackboxes near it, both seem to work however. This part was not touched during the replacement, must be somewhere else.

I don't see what else than that it could be but please let us know when you find the problem ! good luck !

check temp. sensor connector down by thermostat housing, top of lower rad. hose. might have unplugged doing timing belt. fans will run full time if their temp. sensor is unplugged. nice to know if car over heats sometime.

Heres a scan of the electrical wiring routing for a 3S-FE from a factory electrical manual.

The sensors are pretty much in the same spot for a V6 (2VZ-FE).

If you need any other electrical diagrams let me know.

And no I won't scan the whole damn manual, so don't bother asking.
