VT climate control fault (vacuum?)

[tom26]

Hi all,

I have searched all the forums for info and have decided that I have a vacuum leak, possibly in the floor/demister actuator, or a faulty vacuum solenoid pack. The aircon redirects itself to the screen when the engine is under load. I have cut the ends off the vacuum hoses at he manifold and heater valve incase they had got a bit loose, but no change.

The reason I think it may be the actator is when I select the mode to screen and feet, it does not go to the screen, but when I press defog it selects ok. All other modes are fine.

My questions are
1. does the fault diagnosis sound reasonable, particularly with the actuator?
2. Is there an easy way to change the solenoid pack? (I have a replacement item ready to go, just can't get the old one out)
3. Is there an easy way to change the actuators. I can get to one of the mounting screws, but not the one towards the middle of the car.

Any help/guidance/tips would be most appreciated.

Thanks

Tom

hey yeh i have a problem with my 88 vl berlina, the fan didnt work, so i bypassed it, to a toggle switch, but now the selector from feet, face, demister, doesnt work? maybe the vacuum lines behind it are in the wrong order? does anyone have the diagram for it? or could pass me onto a link with it? or could it be the lil glass fuse underneath the glove box? was blown but didnt think it had to do with anything? cheers
