Another Headlight issue

Per Corvette-101.com instruction and diagram. Hoses are fairly new. Connections are good. Line pressure is good.

Situation - Left headlight opens/closes perfectly fine. Right Headlight is stuck in the open position and will not go down.

Trending - Over the past three weeks the right head lamp has delayed much longer too open and close.

Solution - Common sense has led me to believe it is the actuator or relay.

Anyone want to chime in and agree or no? Thanks!

I'd guess relay. Does it open if you close it manually and then turn on the headlights? If not, then the actuator seal is bad. Easy fix with the right seal kit.

The right headlight is stuck open. Does not open or close with the manual pull down switch under steering column

Hi V,
Have you reached the mechanism from underneath to try opening and closing the headlight by hand?
Is it possible that it's gotten 'locked' in the open position because the 'knee' is out of adjustment?
You can pull down on the 'pin' the 4 springs fasten to in order to close the door. The 'pin' is in the center of this picture. Don't pull on the plastic switch; it's pretty fragile.
Once you free it to move perhaps you'll be able to determine the problem.
Good Luck!
Regards,
Alan

ok that worked..it was stuck...the actuators are still very slow and out of sequence. Not that is any surprise but perhaps changing the actuator seals may assist in there struggles...Thanks very much

In over a 100K mi. on our '73 the only headlamp bucket failure has been the actuator seals. Once replaced it was like a new car. Hoses, etc., all original.

Maybe, maybe not. My sticky thread includes some system level troubleshooting checks you can do that should help isolate your problem(s):
