914 Headlights Not Lifting/Lowering Today, Help with Headlights Options

[ClassWinners]

Is there a common reason why an early 914 ('72 1.7) would have all headlights/lifting work perfectly and then after polishing the car yesterday (including headlight covers) with an orbital, today the headlights go on but do not pop up/ lift or retract?

This is a 914 I picked up on Saturday that hasn't been driven in almost 8 years and was stored outside for 2 years. Already got it running! Was tickled when the headlights worked perfectly...but today no lift/retract. Pulled and cleaned headlight relays. Still nothing. Looked like all fuses under the dash were good...although I didn't actually test them. Rheostat, dash lights, tail lights, turn signals all work. Bright light indicator doesn't work, but didn't when the lights were going up and down fine.

If there is a common go-to reason this happens to both headlights it would save me investigating in the systematic approach.

I've owned in the past a 70 911T, 944 and 928. This is my first 914.

Thanks!
