Hello,
on our 2010 T&C is not working passenger and right sliding door window, but they work normally from drivers door panel. Where could be a trouble?

Any info is greatly appreciated, thanks Fred

 

I don't have any experience with the US T&C models, but are you referring to the front passenger window and the rearmost window that opens outwards? Anyway, if they function normally from the driver's panel, it's most likely the passenger panel that is faulty. Did it by any chance get exposed to rain or other liquids? They are pretty robust (and water tight to quite some extent), but on occasion, they fail. If all controls on the same panel are unresponsive, I'd replace it or at least check it. The rear window buttons on my driver's side panel were a bit unresponsive from time to time when I bought it (used car, some 5-6 years old), but after using them frequently they now work as expected. That may be due to some oxide on the contacts inside the switches. Try jiggling your controls multiple times to see if they start to respond.
