I recently picked up this beater 87 blue coupe.
When I got it, both headlight motor gear pucks were F'd.
I put Rodney's Delrin pucks in headlight gears, and all was spiffy....for a week.
Now, the passenger headlight functions normally, but when the headlights are turned off, the driver's headlight has started closing tightly and refuses to come up unless I back off the manual knob a little bit first.... then it works "up" normally.
I assume that this is because whatever circuit in the headlight module is responsible for current detection has a problem.
Does somebody have a rough circuit diagram that shows me where I might be looking for the current detection part of the circuit- there must be a shunt resistor of some sort, right?
