    i have the same problem my fan will not come on no matter what i do. how much does the relay cost under normal conditions?

    I have same error, good relay, fuse blows out when replaced. Possibly short in motor, but i have heard that the coolant temp sensor can trigger this error also, and a bad a/c pressure sensor.

I have a 99 cavalier that is overheating.


Check your temperature sending unit plug and wiring. if there is any corrosion it can cause the signal to be out of range...If it's out of range it can delay fan start up. Works like this: sender sends info to the computer, computer sends ground signal to relay, relay completes power to the fan. If the fan works on a/c, then the fan motor is good and does not need testing. A/c bypasses auto control and keeps fan on as long as compressor is running.
Also, you can have the system tested using a heat sensing "gun" Your gauge may be off a little on the high side. Unless it is actually overheating, there may not be any problem at all.
The gun test can also detect "cold spots" on the radiator which indicate a flow problem. That too can cause your symptom. Don't forget your radiator is ten years old and likely is nearing the end of it's service life. Internal blockage of core passages is common on older radiators.
As long as you have no external leaks and engine internal gaskets are good, something here has got to help!
Good luck!

My 1987 Chevrolet Z24 Cavalier cooling fan will


since you have already tested fan and relay and both work, the problem may be the engine temp sensor. There are two sensors. One goes to instument cluster. This is engine coolant temp sensor, the other is engine temp sensor which is usually attached to engine block, sometimes they are connected to thermostat housing with the coolant sensor. You can pully the engine temp sensor and test that sensor same way as relay. (with mulitimeter)

Cooling fan wont work


The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

Cooling fan not working


The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.
