My 75 headlights will open and close using the under dash valve, however I get no action from the head light switch (other then the lights coming on and being aimed at the ground under the car).
I looked at the vac diagram and I believe that means I have a bad head light switch... do you agree or should I look else where?
I am brand new to the board and C3 owner. Been working on cars for a long while and if I had those symptoms, the swtich would be the first think I would look to replace. I am sure a seasoned owner can give more sound advise.
