Might be the coolant temperature sender? Here it is from the side (but not quite reachable to plug in) and the top. Except my wiring diagram doesn't say red & black, and googling that show the sensor plugged in directly to the engine, not just an inline thing.Sundayjumper wrote: Mon Mar 16, 2020 12:08 pm It's definitely not the power supply to the fan(s) but it could be a sensor. I'd be inclined to plug it in and see what happens.
(or maybe check the wiring colours and compare to the wiring diagram in the back of the manual)
edit: suggestion is the red/black wires are coming out of the a/c compressor, so may have been disconnected by the previous owner deliberately?
