Ok i just bought this car and i dont know what all the switches do. Its an '88 and some stuff may not work so that may be why i cant figure this stuff out. Theres a switch to the left of the steering wheel that sits all by itself. It is a rocker switch and it has what looks like a light bulb and a gauge on it. What does this do? Also on the end of the stick that operates the windshield wipers there is a knob that turns and makes a blue bar go back and forth between "S" and "L" and it doesnt seem to do anything. The third switch i have a question about it one on the center console right by the storage box. It is a black switch with what looks like a red 'defrost' symbol on it. Heated seats maybe? Im at a loss. Any help would be GREATLY appreciated.
