Headlamp Vacuum System
Posted: Fri Sep 03, 2004 9:44 pm
My headlamps on my Elan S4 Sprint, with Non Failsafe units, refuse to pop-up. They move up slightly but not fully even at high revs.
I must have a leak.
I am sure the leak isn't in the front cross-member. (At least I hope not)
It could be in any of the hoses, the operating valve or the vacuum cylinders.
How should I go about detecting the leak? Any suggestions?
Is the operating valve reliable enough?
It could take me hours to track the leak down and lots of money replacing components that don't need replacing. :blink:
Any suggestions would be gratefully received.
