Finally found the part for the air conditioning!

Well, I finally found the part that had failed under the dash of the Volvo that was causing the vacuum leak.

I thought it would be easy, since there were a lot of sites that had the part listed.

I found that they were all showing that the part as being available from Volvo...but I guess it has not been available for a long time. Just looked like it was...

A Volvo executive tried to purchase the car, and even he could not find one in Europe or here. The only reason I found it was that I was also trying to find one for a Bertone 780 Coupe, which uses the same exact part, but with a different drawing. Since they only made a couple of thousand Coupes, I thought that maybe there would be no call for one, since there were so few cars made. Amazingly, I was right!

(I suspect that alcohol, the result of a fruitless 10-day search all over the world, might have been involved...)

Now I can fix this, I can actually see if anything ELSE need fixing...

Excellent work tracking down the part you needed. And the part causing a vacuum leak was??

[81pumagtc]

The vacuum leak was caused by a disintegrating "white metal" disk in the program controller.

The disk rotated and distributes vacuum to various switches and bellows in the climate control system.

Never ever seen, or head of a failure like this. The Puma had the pulleys in the window-wind mechanisms disintegrate, but those were magnesium, and disintegration of thin magnesium castings is a know issue.
