Mine windows have also started to squeak after the car parked 10 hours in rain, so I did what the relevant TSB requested:
- replaced the weather seals (the ones at the bottom of the windows)
- replaced the guides
- aligned the window
The result? On the very first rainy day, they squeaks like before. Here are the "fun" facts:
- I received the 6th(!) iteration of the seal
- even if the new seal looks completely different that the original one, the main issue still not resolved: the felt is simply not pushed enough to the window to do its job
- replacing the guides is not necessary, they can be cleaned and reused (if not damaged, e.g. due to icing)
- window alignment is not necessary as the seals/outer guides cannot be adjusted. The only thing can be adjusted is the inner guide, however, its position can be marked.
- the window does not need to be removed, contrary to the TSB, the outer guides can be replaced by lowering the window and removing the inner guide first
So I got tired and waxed the guides directly....
