Flip-up headlights don't flip-up
I have a 1997 Corvette, and the flip-up headlightslights are not flipping up. Both lights are affected. Here are the symptons:
1. When the switch in the car is turned on, all the lights (including headlights) turn on, but the headlights do not flip-up.
2. When the switch in the car is used, no grinding noise or any other noise is heard by the headlights (but all the lights are on).
3. The night-time light sensor doesn't seem to be doing anything. I checked it at dusk, when it usually works, and it would not turn any of the lights on.
Any idea what is broken? Thanks in advance for all the help.
