A/c and Heater Vacuum help

[Shawnb23]

Does anyone know where to find vacuum diagrams at for a 1968 buick with a/c? I'm trying to get all my door's to open correctly ect... and it's proving impossible.

Check
www.oldairproducts.com
They show a few but I've called & they cannot confirm whether theirs will work in my car. Probably will but I need a definite "YES" before I buy & ship to Canada. Year-One also shows them, a few other vendors will also.
I was able to get one NOS about 2 weeks ago & my buddy will check at Hershey next week for the rest. Year-One or Old Air will get the order if Hershey has none.
Mine is a '71 with probably the same or very similar parts.
I plan to have all the replacement parts in hand in the Spring before I go looking for the problem, which I suspect is either a vacuum leak or a stuck/frozen linkage.

Didn't see any diagrams of the vacuum line's on either website?

[Steve Craig]

My mistake. I read "diaphragm".
You need a chassis manual for '68. Chech E-Bay for good used, possibly someone here has one available.

You need a factory Buick service manual. It has all that stuff. Buy one

[Shawnb23]

Any chance that someone has put it online?

[Steve Craig]

Contact Year One, I know they sell the manual. Your post I think is an owner's manual. What you need is a '68 Buick Chassis Manual.

Shawn, it pays everyday to have one of the correct original Buick copies of a service manual in your hands. Reprints are probably OK as well. Multi make service manulas do not cut it.
