If you haven't already, remove and clean (scrape with small file, sand paper or knife) each terminal of the fusible links, the terminals they fit on, the terminal on the link box and the terminal on the main wire from the battery to the link box. While you're there clean your battery cable terminals too.

The "down" circuit consists of a Red/white wire from the combination switch to the retractor switch on the dash. The retractor switch contains a a normally closed switch which connects the Red /white wire to a Red/yellow wire. The Red/yellow wire runs directly to the plug on the headlight retractor motors. If your problem persists after cleaning all the terminals above somewhere in this circuit is your problem.

Should have 12v in the R/w wire in the combo switch plug when all switches are off. Should have 12v in the R/y wires in the retractor plug at the headlights when all switches are off.

12v to the Red wire in the retractor plug makes motors turn and headlight goes up. 12v to Red/yellow wires makes motor turn in the opposite direction and headlight goes down.

keep them greased as well, headlight assemblies will seize just like the wiper assemblies, sometimes without grease for 20 or more years.
