On the 4th gen TAs..the early ones anyway..if you have a stripped headlight gear..causing the grinding/running noise your headlights will come up, but not turn on when your switch is in the parking light selection. turning the switch one more notch will turn on the already up lights.
this is weird and i havnt cared enough to look into why it happens..it just does..
If you have one side that grinds, or even both(although i know it works with one side grinding) try this. Turn the lights off. unplug the grinding motor. Turn the parking lights on. The other light will still raise. Not shut the lights off, and turn them to park again. Pewf! Only the parking lights will come on. You can now re-plug in your grinding motor and the parking lights will still only come on when the switch is in that position. However, once you use your headlights, the whole thing will reset and the headlights will come up with the parking lights again.
The perm fix? Rebuild or replace the motor.
