The passenger rear window motor operates but seems to struggle, esp going up.

Is this a common tired motor syndrome or is it stiction in the runner??

Hi. Never had a rear go as they don't get used much. Try putting some silicone spray on it (down the runners) or wd 40 and see if it helps...if not have look at the mechanism to see if its rusty or clogged.

Chers, Nick.

This could in fact be the problem, because 'they' don't get much use!
The switches themselves are notorious for having minds of their own & I've even known a switch that has proved to be 'good' refuse to work a different window that, in itself, is also O.K! My Classic only gets used about once a week now & every time I drive it I operate all four windows & the sunroof for one complete cycle.
