'95 Olds, Vin K on engine. Having issue with cooling fans coming on. Both fans come on high when AC is turned on. The only sensor/switch I can find is a three wire sensor in the LIM. I know this sensor controls the temp gauge on the dash. Does it also control the cooling fans?

The cooling fans are controlled by the PCM. The temperature sender is 2 sided if I recall, with 1 common wire, one wire to the PCM, and one wire to the cluster. The cooling fans should switch on low at 216*, and high at 225*. If the fans are coming on with the A/C, that means that they are able to be commanded on by the computer.

What symptoms are you having?
