hi, im wondering if any one has any idea where the vacumme hose goes to from the vent switch behind the dash or any interior vacumme diagrammes continueing from the main pushin coupling??? any help would be appreciated thankyou

I have a genuine workshop manual for an XE. I see what I can find out 4 U. Regards T.P.V.M.

XD's had rubber hoses that perished.....you could replace them with XF ones....they are a plastic type and don't perish.

On the driver side vent switch looking at the switch working from left to right: Solid black, Green stripe, White stripe.
Looking at passenger side vent switch working from left to right: solid black, blue stripe, closest one to steering coloumn blank.
If you are needing the selector switch diagram: working from passenger side: blue stripe, red stripe, solid black, white stripe, yellow stripe.
I do have a diagram I can send you
