SOURCE: can't locate the cooling fan sensor or relay.

the radiator fan relay is located behind and slightly lower than the r/f headlamp.best way to get to this is by removing right side of front fascia out enough to get behind it. this will give you acsess to the relay.i work at a jeep dealer and have done this many times.

SOURCE: Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: cooling fan relay 1998 neon

on the left(driver's) side of the lower rad support. It's a small flat relay with a plug on the bottom and usually has a blue colored front. held on by two screws. Also, there may be more rad fan relays in the underhood fuse/relay box.
Good luck.

Chrysler town&country after overheating getting p1491 code how to resolve it ?


Start your diagnosis at the fan relay module which is located below the battery box on the left frame rail. The Grey wire is hot at all times and fused by fuse #24 in the power distribution center. The Black wire is the ground. The Light Green/Dark Blue wire goes to the Powertrain Control Module which provides ground to the fan relay when cooling fan operation is needed. The Dark Green wire provides switched power to the fan motors.
Using a digital test meter, check for 12 volts on the Grey wire. Check for good ground at the Black wire. If you have good results with those two tests, ground the Light Green/Dark Blue wire at the relay. The fans should start up and run at high speed. Now is a good time to check the current draw on the fans-they should not draw more than 15 amps. If the fans do not run, check the operation of the fan motors by jumpering the Grey wire to the Dark Green wire. If the fans work, the relay is bad.
When replacing the relay, always clean the mounting surface and apply new thermo grease.
To check operation of the PCM, disconnect the connector to the engine coolant temperature sensor and check the Light Green/Dark Blue wire to see if the PCM is switching the ground to the relay. If it does not, check that wire at the PCM connector. If it switches there, you have an open between the PCM and the relay.
Common problems with this vehicle: Poor ground at for the relay, bad relay, bad ground for the engine coolant temp sensor.

Radiator Fan won't work


Check the coolant sensor for operation as that is what tells the CPU to let power to the fan relay to put it on. Check both fuses in the circuit

Try unplugging the temp sensor located on or near the thermostat housing. This will cause the fan to come on, if it works. If the fan does not come on then check for burnt wires near battery and fuse box. You may need to squeeze and manipulate these wires to find burnt area. I have seen coolant temp sensors, faulty fan motors, and burnt fuseible links cause this. When unpugging the CTS the check engine light will come on, don't worry about it.

Overheats if left idling but not if driving...cooling fans aren't coming on...what couls be wrong?


the cooling fans on your car are comanded on by the engine control module which reads engine temperature from the temperature sensor . when comanded on the engine control module sends a signal to the cooling fan relays . which in turn runs the current to the cooling fans . So you might want to check the cooling fan relays and make sure the fues for the cooling fans are good and the relays .if the cooling fan fuses and relays are good it could be a problem with the fan motors or the engine control module not reading the right temperature in that case it could mean you have a problem with the temperature sensor

Yes, in the underhood electrical center, a 60 amp with a red wire going to relay 1 and a 20 amp with an orange wire going to relay 1 and a 15 amp with a brown wire going to relay 2 and another 60 amp with a red wire going to relay 2. The diagram doesn't show a temp sensor, but it does show dark blue and dark green wires going to the power train control module, so it must get the temp input from there. The second fan usually comes on when the A/C is turned on and it apparently gets that signal from there also. Hope this helps.

Replace your temperature sensor. There is a sensor specifically for the cooling fans that triggers the relays, and tells the fans to turn on/off. The relays won't energize unless it gets a signal from that sensor.

1991 Ford Escort fan will not turn on and motor overheats.


some water from the tail pipe is normal but if the car is running bad then it is possible the head gasket is blown. on the escorts that i have owned i have found that the main relay is usually burned and needs to be replaced. it is possible that the fan is dragging and burning this relay up if this relay is good then you may be better off taking it to the electrical shop.

1992 5.0 camaro no cooling fan except with ac


Yes there is a relay, but first answer this question, do you know the fans don't come on until the engine temp is above 230+ degrees F.? That is almost in the hot zone. run a scanner on the engine and watch the ECT sensor temp reading to verify proper cooling fan operation, a quick test to see if the system works is to unplug the ECT sensor, the fans will go into failure mode and turn on to avoid damage to the engine.
