Hello. Im new to this group, anf I have a 67 riviera that I'm starting to work on. The hideaway headlights don't work when I turn the headlights on. I have put power directly to the motor and they open and close properly. If i manually open them, when I kill power at the headlight switch, they will close but not open back up by turning on the light switch. Any ideas? Should I start by replacing the headlight switch?
