Rear window regulator / High mileage PM?

[tomgtv]

I was pulling out of the gas station today and was raising my right rear
window. Big popping sound and window fell down into door, won't operate.
I assume broken regulator.
I went to this very helpful site and saw the info on removing door panel.
I have done all recommended and the rear panel seems stuck about the
door handle. I did see and remove the screw in door handle area, removed
the rear quarter window shade. Any suggestions?

What do you think broke? The cables, the window clips??

I had my driver door window go a couple years ago. It was a pulley cable that separated. Now they use a solid pulley to eliminate that one.

BTW, I have 113,000 on my X5. I drive a lot of freeway here in FL so hoping to run this machine over 200K.

I've done the sparkplugs, radiator fluid, and always change oil / filter at 10,000 miles with synthetic. What about ATF fluid? I see it recommended here, how much does it take and approx cost? Is is DIY??

Thanks all
Tom
