Engine Fan Stuck On
There is a bit of diagnosing with this Gary. The fan relay or controller could be stuck, as well as a bad coolant temp sensor, A/C switch, or even a faulty trans temp sensor, all of which communicate with the PCM to turn on the fan as far as I know. I’m pretty sure one or two more items also involved in the PCM’s algorithms but currently drawing a blank.
Mines been on high for probably four years now because lazy.. I’m pretty sure mine is the fact there is no more trans temp but I’m not motivated enough yet to add a resistor to trick it. Maybe next year.
