What's an easy way to get the lower allen screw off the distributor cap? The fan is in the way. Also my drivers door stopped illuminating the interior lights. Passenger door works. The drivers door switch has a good ground entering and leaving the switch. I lowered the door light under the door (which doesn't illuminate either and when I touch the ground side of the bulb contact with an old fashioned test light I hear a click under the dash and the interior light illuminates and stays on. Any ideas? Is there a control module that's bad?
