The cooling fans have completely stopped turning on. All of the fuses (6)for the cooling fans have been tested and are in working ordered. The ground for the cooling fans has also been checked and is making contact properly. What else can the problem be?

SOURCE: 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.

SOURCE: Cooling fan won't come on.
First question to you is.. Have you checked the wiring or ECU codes?
check the cooling fan switch on the back of the block, unplug the connector and jumper.
2 wires, turn ignition on and fan should come on...
if it does-----replace the cooling fan switch
if it doesnt----- go to the cooling fan relay on the pass side inner fender
panel behind the headlight and check it, besides the fan itself and the fuse, those are the only things in the system.

SOURCE: cooling fans wont turn on
Hello. I understand your frustrations as I too own a 2001 monte carlo and have had the same problem...along with several others. My engine temp gauge would show ZERO degrees because of the bad coolant temp sensor. So I replaced it with one from autozone (BIG MISTAKE) The one from autozone was **** and gave the car a different problem. The fans would not run while the engine was running and would run when the engine was off until the battery rundown protector would shut them down. this lasted about 2 weeks during which I had to keep my heater on (in the middle of summer) to keep my car from over heating because my fans wouldnt run. The autozone jerks said "if my temp gauge was working then the sensor was doing its job" and that "there is another problem" Well I finally called the dealership and they told me that autozone is junk and to try advance auto parts and to get the next one up from the cheapest...this is what they use...and NASCAR uses. It was a few dollars more (around $25) Problem solved. However a few months later the cooling fans went completly out..this was due to them experiencing such high temperatures for 2 weeks. I replaced them with ones from a salvage yard for $50. Dont let this happen to you...

I had the same problem, took it to the shop and found it to be the electrical connectors. They were burnt. You might want to check those.
