c3 vacume system

<< < (2/2)

77CVT:
Do they work fine with the engine running?

MADLT1:
they only come up ,wont pull down,allso I have not been able to get wiper door working yet,i will spend some more time on them tomorrow,but I am thinking new relay valve for the wiper door and headlight switch

sirfixalot:
The control circuit small hose on vacuum valve has no vacuum so the vacuum solenoids are de-energised. The headlites go up when vacuum cut off from the diapram  check the over ride switch under dash or the headlite switch a few years ago there were diagrams on the net with headlite connections back to front. Will only work one way

MADLT1:
well what I just did was swap out the wiper door relay with one of the old headlight relays,and now it all works,unbeleivable lol,i will buy a new relay and check valve now and that should just speed it all up plus hold vacuume in the resavior tank,thanks for all the input,cheers
