2003 forester with po 691 code good fuses and relays. what's next
1 Answer
Finding the code is one thing; fixing it is another. It's diagnostics. Might be a fault in electrical wiring, particularly grounding. Might be a clogged radiator or defective water pump, or a bad fan witch, or engine coolant temperature sensor. If you can't find it, have a mechanic do it before you drive the car again.
