Question about 2004 Ford Crown Victoria
Cooling fans run
Posted by Anonymous on
Based on your question, I am assuming that the coolant fans are running? They should be, well they should if the temp gets to the a certain level. Not all cars have only one but some have two fans set up on different temp on/off. If you wish to check them to ensure they are running, you can check the electrical current from the temp sensor to the fan switch to ensure there is current going to the fans, obviously if not...that would be the problem. check out this video with all of these how to do yourself described....

Make sure the radiator pressure cap is the correct one and that the hose is not soft--check the lower hose and heater hoses for softness as well. They should be firm, but not hard or cracking. The temperature sensor is reporting normal operating temperature, so it and the thermostat are working correctly (hot water would blow out of the radiator if it were stuck). Check the cooling fan for free turning and no noise. Check it's grounding connection. Check the fuse box for blown fuses to the fan and to the A/C compressor. Make sure all the relays and fuses are firmly pressed into their sockets. Check the A/C compressor clutch winding for resistance--should not read infinity. Does the blower motor for the heater/A/C run when either is turned on? The A/C switch on the dash may be defective.

Testimonial: "Excellent suggestions for diagnostic checks! Thanks!"
The Taurus has Two temp sensors. One for the dash, which is isolated, then one for the PCM, it also controls when the fan relay should actuate. Its a 2 wire sensor, just above the thermostat. If you remove the harness from that sensor, and the cooling fan comes on, at any temp, (should take 5- 10 seconds) then thats your fault.
