Look at the coolant sensor it also controls the fan,one way to check is to turn on a/c see if that over rides it
Check coolant reservoir level.
SOURCE: cooling fans on 2001 chevy malibu will not come on unless ac on
the relays control circuit is grounded by ECM (computer) . to check this make sure the is hot enough for the fans to be commanded on by computer and check to see if you have voltage at relay and it has ground from computer . you may need ECM.
good luck
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: The low coolant warning light comes on regularly
it is a float inside the coolant recovery/overflow tank which is easy to replace

Cooling fan relay switch (in the fuse box uner the hood). Look for othger relays in there that are the same type number (they are all marked). If you find one that is the same as the cooling fan relay, then swap the two relays and check. (Turn on car and turn on A/C ... fan will start ... or not).
Fan motor could be bad (most likely).
If you remove it yourself, don't scrapr the radiator fins with the fan blades.
Hope this helps!
