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

the light is flashing to tell u that the engione has one or more engine cylinders misfiring, have the trouble codes tested to find out which cylinder(ws) is he problem.
