Shift into 4H for now, the light should stop flashing and then replace the freewheel clutch solenoid located under the air box at the fenderwell.

2003 Mitsubishi Montero Limited. 97k miles. Temp gauge is erratic when actual temp is normal. How do I fix this?

Follow the top radiator hose down to the water outlet. The thermostat is inside the water outlet,Just remove the bolts,replace thermostat,replace gasket,bolt back in place.

If your car has climate control, remove the glovebox, and change the heater temp from the lowest to the highest setting. you should hear the electric motors pulling cables in the dash. it's probably a faulty control unit in the dash, you're certain there's hot water going through the matrix?
