68 GP

[Pontiacdaver]

Hi, anyone out there know where I can get a vacuum routing diagram for my 68 GP's hidden headlight system? I just bought the car, and they are stuck in the down position.They aren't covered in either the 68 Service manual or the Fisher body manual. I will probably end up just tracing it from beginning to end, but if anyone can help, I'd appreciate it.
Thanks, Dave

Nevermind, I found the problem.....guess the previous owner didn't know one of the outlets on the washer pump wasn't a vacuum source. Dave

I had luck with a Detroit Iron manual when I was running vacumn on my engine, hope this helps
