I need the weather strip only for my rear sliding power window on my 2012 F250. I think I have the right part number as 8C3Z2542052E, but this includes the sliding window as well for about $100. All I need is a $10 piece of rubber weatherstripping. Anyone have any suggestions?

 

Could possibly still be under warranty. Be more specific about where this piece fits. Does it go all of the way around the window?

 

I have over 100k miles...no more warranty. I learned there are two drains in the track. Sure enough they were clogged. I have one cleaned out the other is being difficult. I am still working on it. I also learned the weatherstripping cannot be purchased separately - must purchase entire slider assembly and window.

 

You might try a salvage yard.
