Engine heat s up fan not working


can you make this a bit clearer. so, you are saying that when the engine temp reaches certain temp the fan does not coming on when it's supposed to? first check all the relays and fuses, if everything is ok and still fan not coming on I would unplug the fan/s and run a straight 12 volts to the fan motor, if it does not come on it means fan motor is burnt.

99 chryler sebring 2.0 radiator fan not working


1 check fuse and or make sure you have 12 volts at fan conection
2 the fan has a thermostat to tell it when to come on when water temp gets
to about 160 or so, check for 12 volts at fan connector when motor is warmed up if no 12 volts replace thermo stat
3 check fan motor whith an ohm meter, if the reading is zero then the motor is bad and ned to replace the entire fan unit. cheep at junk yards

Hi

Unplug the coolant temperature sensor while the engine is running. This should cause the fans to turn on low then kick to high, IIRC.
Typically when the engine computer loses the signal from the coolant temp sensor, it just turns both fans on high so the engine will not overheat. Ultimately, the fan is controlled by the computer. When it receives a signal from the temp sensor that reads the appropriate temp, it turns the fan on. One easy option is to wire a switch to the cooling fan relay. Then you can turn it on and off when you need it. I would not recommend running the fan constantly. You will burn out the fan motor and you'll never get up to normal temp for your sensors.

Check for coolant level and bad motor.

However as far as the fans and "disconnecting them from the temp sensor"..... The fans DO NOT connect directly to the temp sensor. They connect to the PCM (computer). The PCM reads the coolant temp sensor, and determines when to turn on the fans. It also uses the coolant temperature to control several other functions, including the transition from "open loop" A/F ratio control to "closed loop" A/F ratio control. It uses the temp to set the idle speed on cold start. It uses the temp to determine the cold start fuel enrichment. If you run this way, your car will be hard to start, it will run excessively rich, wasting fuel, and possibly even damaging the engine by diluting the oil.

double check the 60 amp fuse in the engine compartment fuse box, then check the relays. Do you have 2 fans or 1? My manual shows 2 fans and 2 relays. Fans are controlled by the PCM with inputs from sensors. To check relay socket for PCM command signals, see my post at http://www.fixya.com/cars/r6022358-relay_check . Looking into the relay socket, you should detect two terminals with 12 volts and one with a motor load. The last terminal will be open until the PCM tries to turn the fan on--then it will be a ground signal. You'll have to get the engine hot to see if the PCM is doing what it should. If you have questions, please let me know.

Most systems work this way: temp sensor on engine sends a signal to the computer which in turn sends signal to blower relay that then sends signal to the fan.
Any problem along the way, and the fan won't come on.

Check the coolant temperature switch. You should have 12V on one side of the switch. If you jumper the two wires in the switch connector, your radiator fan should run with the ignition switch on. If it runs, replace the coolant temperature switch.

Change the fan resistor it should be located under dash near the glove box ther's a rectangular electrical plug going to it it should be located somewhere on the heater box. These usually go bad because of the constant condensation and temp. changes present.
