RS Headlamps trouble shooting
« on: October 30, 2010, 05:37:37 PM »
Im in the process of figuring out my headlamp doors,I think I know the problem. The headlamp switch seems fine I pull out the switch & vac is cut off at the orange hose.At the vac relay I have vac on the green nozzle with the switch" in the "normal" position.That will close the doors & keep them closed.When I push the switch to the open position I still have vac on the green nozzle & no vac on the red nozzle.That tells me the vac relay is bad. Correct? Also if I put vac on the green hose from the vac relay"by passing vac resovoir & vac relay" I still have vac on the red hose & vice versa.That tells me I have a leak in the actuators too.If I hold my thumb over the opposite hose im not vacuumizing & release my thumb the doors will move,not all the way but if I continue to do that they will open or close all the way.This sounds like I have a bad vacuum relay  & bad actuators does this sound correct?
