Fan stuck on! Won't turn off!

As the title states, a few days ago I went to start up my car in the morning and the cooling fan came on. Weird, cause it wasn't even warm yet.

The fan is suddenly stuck on and won't turn off.

Like literally, if I go and turn on my car at any time of the day, with cool engine, the fan will come on when I flip my key to accessory.

Bad t-stat? What does R3V think? I rarely used to hear my aux fan come on. Now it won't turn off!

Is your A/C button depressed? Try replacing the switch for it if that is not the case. New ones are not overly expensive.

Nope! Tried that .. it's off alright.

Bad thermostat on radiator or stuck relay (less likely...)?

Check that aux fan switch on the radiator?

Unplugging the wiring harness from the temp switch will tell you if it is the switch or not. If it turns off, then it is the switch. If it stays running, I'd say it was a stuck relay or the AC switch is shorted somehow.
