SOURCE: can i bypass the cooling fan on a 97 chrysler

Answer is yes, Question is why? Might be as cheap to fix problem, as to wire it other way. Just be sure to fuse it. Personally if I had to do that, I would at least put a switch (illuminated) in the dash to allow me to shut it off, if running too cool. Believe it or not, Running too cool can cause problems as well, like more fuel consumption.

SOURCE: Coolings fan keeps running

the cooling fans are switched off and on by a relay. either this relay bad and staying on all the time, or something else is bad and telling it to stay on all the time. you might unplug the engine coolant temp sensor and see if the fans switch off. if they do you have a bad temp sensor, if they don't you probably have a bad relay. they will test either for you at most car parts stores. the relay will be in the underhood power distribution box, it plugs in like a fuse. disconnect the battery negative terminal before you start unplugging things from the power distribution box. hope that helps

SOURCE: cooling fans

Your primary should turn on just before the car gets to running temperature. The other fan should only turn on when the A/C is running.

SOURCE: Radiator cooling fans do not come on

I would say to simply have the thermostat tested and checked. The job of the thermostat is to monitor the temperature of the engine/engine bay. If it gets too hot, then it is supposed to kick on the fans. If this is determined to be bad, good news is that the part is not very expensive and not much labor is involved to replace it.

On the other hand, it is also possible that the fans are bad. Either way, both can easily tested by a mechanic.

Good luck!

I saw on google something warning to not jumper wire the cooling fan. What might go wrong?


One you could burn up the circuit you are pulling power from, and two if you run it from the battery you could forget to disconnect and run the battery dead.
One way the engine computer controls engine temp by turning the fan on and off. So running the fan all the time could keep the engine from reaching normal temp.

Where is the cooling fan temperature sensor on a 1993 Chrysler lebaron?


The LeBaron uses the Coolant temperature sensor data for both the engine control and the radiator fan control. The PCM sends a closure signal to the Radiator Fan Relay when it wants the cooling fan to run. There is no separate switch for the fan itself.

Fan continues running after turning off ignition


HI. This will, generally, be the result of the cooling fan switch.

The cooling fan switch on most electric fans monitors coolant temperature signals from the engine control computer. When the engine is cool, the switch opens to keep the fan from spinning. When the engine is warm, the switch closes, thus, turning the fan on for cooling.

I would advise to Inspect the cooling fans(thermal switch),wires and connections. Cooling fan switch problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the switch itself. If the wires or connections are bad, replace them. If you think the switch is defective, it should be tested.

The electric fan cooling switch, or thermal switch, can be tested by placing the element in a bucket of water. Heat the water to approximately 207°-216°F (97°-102°C) and connect the switch leads to an ohmmeter(make sure to keep the switch leads out of the water). The switch should have no continuity until the temperature reaches this level. Let the water cool off below 207°F (97°C) and the switch should lose continuity. If the switch has no continuity at any temperature, replace it.

NOTE_The thermal switch is located on the top of the radiator, usually on the passenger side.

The next thing you should do is run power from the battery in to the fan and see if starts spinning, if not you would need to replace the fan.
