I have a 1989 Lincoln town car. My thermostat gauge keeps going up and down. While I'm at a light it moves up and down as my blinker does. If I roll the window up and down it blinks also. I changed the thermostat put new antifreeze in it and put a new radiator on what could it be?
My car has 144000 miles.
My car has an automatic transmission.
