Radiator fan on my 1994 toyota camry

Only when my A/C is on the radiator works other then that it doesn't work. what could be the cause of this?

    ok you said the fan would come on when my car gets hot enough but it doesn't. When the A/C is on the car doesn't get hot at all but when it's not on and i drive for almost an hour or less in traffic my car acts like it's going to over heat and when i stop no fans come on. This leads me to believe that it's either the temp sensor or faulty fan relay. If it is the fan relay which one operates it? I have 3 relays on my 1994 toyota camry. I want to be able to not have the A/C on while I'm driving :)

There are actually 3 temp sensors. 1 is on the top of the engine that goes to temp gauge in dash has 1 wire. next to it is a 3 wire sensor for engine control and choke. on the bottom of the radiator next to the hose is a 2 wire sensor. loosen all 3 but leave connected. get engine hot past halfway point on dash gauge. with ac off disconnect 1 sensor at time. start with 2 wire under radiator. it takes the most abuse. fan will come on when you disconnect broken sensor. 2sensor must agree for fan to stay on till engine cools when turned off. note this is solution i used after verifying fuses, fuseable links and relays worked.WOO HOO! make sure you check both the fuse box under hood and fuse boxleft side of steering wheel my ECU fuse was inside my bros was outside.ECU B on my car goes to nothing and is under hood. Had it confused with ECU on wiring diagram.DOH!

    skitzzer420 Your solution to this problem is the most succinct and thorough of any that I have seen. You covered all the bases and made it clear to me. I turned on the AC and my fan came on, leading me to conclude that the lower radiator temp sensor (aka fan switch) is bad. Problem is it is hard to get to. I tried to get the connector off and could not, due to the proximity to the lower engine mount. Do you have to access it from the bottom? Do you have to drain the radiator to R

The Radiator fan will only engage if the engine is above a certain temperature, with one exception, it will run continously with the AC. If the Fan works with the AC you can be assured that the fan works properly. Unless your car is overheating, it is simply not getting hot enough to need the fan.

    I would lean towards the temp sensor. The AC, and the Sensor should use the same relay to turn on the fan. The fact that the fan runs with AC Means the relay and the fan should both be good.

SOURCE: 1994 2.2L toyota camry radiator fans do not work

Hi.....

The Normal Temperature Range to the Fan Start is: A/C ON 181 F.
A/C OFF 199 F. When the Engine Reach this Temperature the Fan should start.

OK. Do this simple test.
1---- Start the engine, Desconnect the ECT Switch located on the Radiator,
See if the Fan come ON. If yes, if not go to step #2
Connect the ECT SWITCH and leave the car Running and with a Temperature gage.
See the temperature, if the Temperature go more than 199 F.
Turn the Engine OFF.
Disconnect the ECT sensor and check for Ground at the WHITE/BLACK wire.
If ground exist, Replace the ECT switch.
But if not. Check the wire for any damaged, and the ground at the Front Left Fender.
Repair as need.

2---- check the Fuse link RDI FAN . 30 amp.
Check the Fuse link CDS FAN 30 amp.
Replace if need.
And Return to step # 1.
Check the Radiator fan Relay, Rad fan relay 2 and 3. Replace if need.

Ok. I hope this help on your question.
I can give to you the WIRING DIAGRAM of the Fans, But I need a E-MAIL adress to do that.

Thank you for use fixya....

SOURCE: Toyota dealer installed a new radiator in my 1994

they probably had to disconnect the a/c condenser to remove old radiator and failed to reconnect it when the new one was installed. a/c won't work without it. i would make it their problem, it's not your fault. if they also caused your system to lose freon charge they should make that right too. the condenser is a little flat thing in front of the radiator, sort of looks like a radiator itself. refrigerant lines will run from compressor (it's a round belt driven thing mounted to front of engine) to condenser. they either didn't hook it up back up or somehow damaged it is my guess. hope that helps

My 1994 toyota camry is ovverheating even when the water pump is new and the radiator are goo, no leak the hoses are good The car is still overheated


If this happens very quickly, it is probable you have a head gasket leak to the coolant jacket. There is a simple test a mechanic can do for combustion gases in the coolant.

If the car warms up normally, then keeps getting hotter, the temp sender may be faulty, causing the radiator fans not to run when they should start. Check they do run when the engine is getting hotter.

Or, the thermostat could have failed closed, not allowing the coolant to circulate.

94 toyota camry xle v6 overheating noticed leak in overflow res.


I think the leakage out of the reservoir is being caused by the overheating, not the other way round.

This can be caused by several things:

- failed thermostat (not opening)
- failed temperature sensor (not turning on the fans)
- blown fuse or failed relays in fan supply (if electric)
- soft hose from radiator to water pump "sucking in" and preventing flow
- blown head gasket allowing combustion gas into the water jacket (less likely)

Coolant fan switch


it's hooked up to the temperature sensor. if you don't get a temp light on, the sensor might be bad. it's usually located where the upper radiator hose goes into the engine. also check your thermostat.
