Why does your cooling fans not work when plugged in to the temp sensor but work when its unplugged from the temp sensor?

Is the car overheating? As a safety measure, the fan will come on when the coolant sensor is unplugged. This is in case the wires come unplugged or the sensor goes bad so that the car will not overheat. If you have A/C the fan should come on within a few seconds after turning the A/C on. The fan on the car does not come on simply because it is plugged in to the sensor. It first has to get fairly hot....something like 238 degrees before the fan will come on. This is a how a correctly functioning fan will work. If it is not coming on when the gauge reads above that you may have to take it in to find out why. It could be a bad sensor....likely......or that the computer is not reading the signal correctly and thinks the car is running cooler than it is.

Why wont your cooling fans on your 2002 grand am gt not working?
The cooling fans on a 2002 Grand Am GT might not be working because of a problem with a fuse. There is also a temperature sensor in the engine that tells the fans when to come on. This sensor may be bad.

first you need to make sure both of your fans work by doing the following step 1- unplug your collant temp sensor and start your car, if the fans run, then replace coolant temp sensor, step 2- if the fans do not run check the relays that are located in the fuse box under the hood, their are 2 of them, step 3- if relays are good and the fans are not coming on while the coolant temp sensor wire is unplugged and the car is running then you fan motor needs to be replaced

Does the coolant level sensor turn the fans on?
No, the electric cooling fans turn on and off by a signal from the coolant temp sensor. The coolant level sensor only illuminates the low coolant light when you are low on coolant.
