1966 Hideaway headlights do not descend

Asked by Sep 18, 2015 at 11:16 PM about the 1966 Buick Riviera

Question type: Maintenance & Repair

I have owned my 1966 since 1990 and headlights have never failed to drop
down when headlight switch is activated. Tonight they do not drop, but are
illuminated.
Are there recommended initial trouble shooting tips?

thanks,
Dennis W

gotta know if they are vacuum powered. if so youve got vacuum leak somewhere i imagine

Is there a vacuum reservoir? A vacuum harness going to the switch ? hoses out at the lights them selves ? Then, if they also stay illuminated when you shut them off ? Thats very unusual, are you sure you said that right ?

This is going to be a vacuum problem. Check the vacuum hoses and vacuum actuators at the headlight doors for leakage. If both doors are effected start at the headlight switch and work your way forward to the headlight doors. The headlight switch has a vacuum valve as well as the electrical connections to open and close the doors and, at the same time, turn the headlight bulbs on and off. HTH. -Jim
