Hi there, you probably have an answer to my questions, I thank you if you do-. Please help me! 2000 Ford Taurus 3.0L Flex Fuel, overheated today. A/C opertaion intermittent. I checked the cooling fans and neither were running. A shop looked at the car quickly and said both the cooling fans were shot a $400 fix, I don't believe it. I Let the car cool down and drove it home with the heat on and the temp guage stayed normal. Coolant level in radiator is normal (it was down alittle bit from steaming) Later opened the hood and started the car(cold). The fan on the right kicked in right away, the one on the left did nothing. I drove the car and got it hot and came back home, opened the hood and neither fan was on or would run now. Tried the A/C and it wouldn't kick in the radiator fans either, and the A/C was not blowing cold.

I am going to check each of the fans tommorrow and see if they run when I put current to them. Is there 2 speeds in these motors? Whats the best way to tell if they are no good? IF they do run, where are the control relays for these located or the sensor that turns these on- located? Or whatever you believe is causing this? I checked the 40AMP fuse in the engine compartment for the fans and it is not blown.

Any knowledgeable hep would truly be appreciated!

You might want to check the operation of your coolant temperature sensor. This sensor has a bimetalic core which will cause a variable resistance. This information is sent to the ECU and at a preset level the fans will change speed. The fans should ALWAYS be running while the engine is on. The fans are very simple to replace yourself, so if the CTS or the fuse is not blown then the fans themselves may not be functioning properly. You can always try shorting the fan to a 12V source to check the motor operation. There should be an electrical disconnect on the motors themselves. Remove this and use a set of wire and jumper it to the battery and see if they operate. You might want to place a 40A fuse in your circuit so you don't damage the fan if there is nothing wrong with it. Use the correct guage wire. Now is the A/C system have the proper refrigerant charge? Does the compressor turn on? Please make sure you fix your engine cooling issue before you tackle the A/C, they are two seperate problems.
