Just wanted to share the results of my last fishing expedition to a local wrecking yard. They had a reasonably well-preserved 1997 S90 with 168K... Probably a little too old and not particularly low mileage but I was looking for some experience with the climate unit box removal, and wanted to see the vacuum servos in person... The work wasn't really that bad (glad I didn't have to put things back where they came from, but I don't think I damaged anything except the aluminum AC pipes, just didn't have patience to disconnect them properly. I salvaged two servos 9463041 -- the ones for dashboard vents (pictured). The other two: 9463042 (defroster/floor) and 9463040 (recirculation) had more complex shaped membranes and were both visibly damaged (rubber cracking). I'd be comfortable putting the ones I've got on my car, or leaving the originals in place (I think the operation is tested easily with a vacuum pump). For the\ defroster/floor one (that one was in the worst condition, clearly) I'd be happy to use a GM part (1996686) -- do you know if the recirculation one (9463040) has a suitable replacement in the GM catalogue? Checked with all parts sources that show up in Google, and even wrote a message to Volvo Cars North America -- looks like the Volvo parts are gone for good...
