Question about 1992 Buick Regal
Change temp. sensor, maybe your sensor went bad, check fuse, fan relay
Posted on Sep 09, 2010
First check fuse in engine compartment. Use a test light to check for voltage at the fan connector. If no voltage at fan with engine running and hot, replace fan relay in engine compartment relay box. If there is voltage at fan, but fan doesn't run, replace fan. Any questions, please reply.

SOURCE: cooling fans will not run
Most GMs use a relay package to turn on the fans. That is often controlled through a processor package. Very complicated...if yours is one of them. You will need Mitchell's manual or equal to trace this to see if you have all the signals.

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.
