The fans are controlled by the ECM and it uses the ECT sensor for temperature sensing, so if the check engine light isn't on the sensor is not the problem. You need to have an active test run on the fan system to see what code is returned. Have you tried powering up the fans at the relay?

SOURCE: my 1998 buick regal non turbo 3800 radiator

the electric cooling fan for the radiator will not turn on when the engine reaches normal operating temp, its only supposed to come on if the engine temp goes over the normal temp. (around 220 degrees)
it is normal for the fan to come on any time the a/c or defroster is turned on.

SOURCE: fans run constantly

Irwinr12 is right, no amount of fan will keep the Regal from warming up if the thermostat is working properly, Replace it. Clear SES light with OBDII tool & you should be good to go. BTY its the car computer that keeps the fans running, and they will continue to run until you clear the code. Any kind of cooling/overheating proiblem will kick in the SES light and set both fans running. I own '01 GS, my son has '03 GS and we have both complete set of service manuals. Trust me, do what I say. Batman

SOURCE: I have a 1993 buick regal custom with 3.8 V6 fault codes

Idle position switch or sensor. I had 93 that would stall when i came to a stop. Cost me $43 but it was worth it. I don't know if this will fix it, but it sounds like it would.

1999 Buick regal gs heater not working if i hit top of dash or the side it will come on. But now that isn't working please help


If its the fan thats not coming on then i would check the blower motor resistor these are known for losing there connection at the pigtail.The location is usally on the passenger side down close to floor mounted on the heat duct with two screws.First try wiggling the pigtail with the ignition and fan switches on.

2000 buick regal blows high fan fuse as soon as it is put in with car offf


I would disconnect your blower motor resistor then try fuse again, if it does'nt blow then it is either blower motor or resistor,these resistors are common for going bad/and or blower motor. Good luck let me know if you need more info or if this didn't fix it, I will research it more for you

Cooling fan not activating


On most vehicles, there is a thermostatic switch located on the bottom tank of the radiator that controls the electric fan. When AC is turned on, this switch is bypassed so its failure is 'cured.' These switches aren't terribly expensive nor difficult to replace but ensure you don't lose coolant on the ground while replacing the switch since the stuff is tasty and toxic to animals.
If you like to be able to research and or repair minor problems like this, you might consider buying the Haynes manual for your car. This will also let you approximately access what a repair might cost for labor if you can see the degree of difficulty yourself.

These are available at auto parts stores often cheaper than the online price. We have on for (and IN) each vehicle we own since they can be lifesavers now and then.

If it is not on the front of the motor, it is more than likely on the back of the motor. Just jack up the car (be sure to put a jack stan under for safety) then crawl under and you will find it
