Cooling fan always on when battery connected

If the engine is not hot when the fan turns on, I'd be concerned about a possible sticking relay or some kind of command to turn the fan on. Hands on testing is needed - perhaps get a wiring diagram (not available here...try ALLDATA DIY maybe?) to find out relay and fuse positions so you can check there, or find a shop near you that can assist. https://repairpal.com/auto-repair-near-me
