    GM all,
I have a 990 that runs the cooling fan full time. I have not trouble-shot this yet with the schematic, but my guess is that a former owner may have wired it this way for a heavy duty-cycle mode such as rtty. Or depending on how the sensor is wired, perhaps there is a shorted or open thermistor? Any suggestions? Thanks.
