Re: 69 RS Headlights not working
I don't know what you don't like about the headlights, but, I would just by-pass the switching valve.
Remove the top hose on the switching valve, and the center supply hose. Join the 2 together with the engine running, the headlight doors should open.
If you do the same, but use the lower hose instead of the upper hose, the doors should close.
The headlight switch should allow vacuum to the top (control) port of the switching valve when the headlights are off. No control vacuum to the switching valve, the headlights should be open.
I don't know what color hoses should be where. Just that the hose on the rear of the actuator (open) should go to the top port on the switching valve. the foward actuator hose (close)should be on the bottom of the switching valve.
