I’ve searched every combination of words I could think of but unable to find anyone with same problem, I’d hoped someone else may have had it and solved it previously.

Ok I have 2011 WRX that I bought new. I can count on two hands the number of times anyone has ever sat in the back, so the rear windows have rarely been used.

With both the rears, if they haven’t been used for a couple of weeks, they don’t work at all. I have to hold the button down every time I drive it for days, and sooner or later, out of the blue one will suddenly work, then eventually the other will too.

I then have to wind both down (even just an inch or two) and back up every couple of days to keep them working.

Just now the driver’s rear is fine, passenger side not working. If I persist it will eventually come good, until next time I don’t wind it down and up for a couple of weeks.

I know that sounds odd but it drives me nuts, if anyone has any ideas I’m all ears and appreciate the help.
