Last year my right rear window failed to rasie after I had lowered it. So I manually pulled it up. It will still go down via the power button but will not rise. Since no one hardly ever sits back there I wedged it shut.
Yesterday I ran my left rear window down and it failed to come back up. I can manually push this windows up or down, or lower them with power button, but not rasie them without manual manipulation.
Can anyone tell me what going on with these windows, and can I fix them myself

It seems I remember reading somewhere about these cars' windows jumping off track or something like that. You may have to remove the door panel and see what's going on. I found this on the E34 but may be similar on yours: BMW E34 Website

Thanks for the reply, even though that' what I'm afraid for. Are they costly?
regulators for E39 are like $125 each, I had to replace one when I bought mine a couple years ago. Same problem, would roll down but not up. If you pull the inside door panel apart you may be able to determine the problem just by visual inspection.
the weakness in window regulators(in practiaclly all cars) is the plastic runner that runs through the window regulators rails while your window moves up and down. They're made of plastic, and made to rub against metal rails.... (for the shooosh of operation) but they do break into pieces over time. on some models, u can replace just the plastic pieces, and on some models, they are riveted in place.
Depending on how creative u are(as these plastic pieces are available on eBay) u can choose to just replace the plastic OR..... "dread", bear the cost of replacing the whole regulator.
i.e. on BMW, Benz & Ford.. the regulator costs an average $200, but u can buy the plastic runners on eBay for $4.-(plus shipping) knock out/grind out the rivets from the old regulator, replace and then rivet the new one's.... and then re-install.
