Special tool needed: a female with small hands. Do you have a wife, g/f, neighbor, etc. to help you?

The dual pods are the ones that are troublesome to rebuild.

Do a search, I cant remember the guys name, but HE SAID, the vacuum pod rebuild diaphrams was a little different than the ones he was replacing OE. Even with the new diaphrams, when compressed, the rod does not move the full length of travel. In other words, your vents wont open all the way with the rebuild kits.

This is just what THAT guy said, not from my expereience. Personally, I bought all new pods from the dealer. This way if it does fail within a year, THEY have to take everything apart and replace it for free under their warranty program.
