1993 Camry If the radiator cooling fan switch has been replaced what else would cause the cooling fans not to operate when the engine overheats?
What do you mean by ``switch``? Coolant temp sensor could be bad, Fan relay could be bad, or fans could be bad. Is radiator completely full? An air pocket could cause problems. By switch I mean the temp sensor located on the radiator itself. I have put direct voltage to the fans and they operate. The radiator is new and full of antifreeze. On this particular model there are two boxes with relays and fuses under the hood on the driver's side. Box that is closest to the headlight has one relay listed as fan no1 and the other box has relays listed as fan no2 and fan no3. Which one of these operates the radiator cooling fans? Is there a way to test these relays? Does engine have another sensor near thermostat housing? This is normally the one that controls the fans. Either way, if sensor has one wire to it , disconnect it and ground it to engine with ignition on. fans should run. If not, it is probably a relay. If you have air conditioning, the fans will both run when you turn on the air conditioner with the engine running. (At least the 1998 Camry is this way). Both fans run to keep airflow over the condenser coils. If both fans run this way, then wiring, relays, etc. can be assumed to be alright. Then more than likely, your problem is the radiator temperature switch (you will see wires going to a device that is screwed into the radiator near the bottom, by the lower radiator hose) This switch should turn on the fan when the radiator fluid gets hot. I am not sure this fan will run when the car is turned off but at least you know the wiring and the fans themselves are operational.
Will the relay switch effect the cooling fans?
Yes. Most cooling fans are controlled by a relay because they take too much current to be wired directly.
