How To Change Window Track

I Have A 1999 Olds Alero The Driver Side Window Dont Go Down The Window Is Fine The Motor Work Good I Can Hear It And See It Move
It Looks Like The Thing That Keeps The Window On The Track Is Broken Any Help Would Be Great Aso Pictures

The same thing happened to my window on my Alero.
I had to buy a new regulator. I bought it on ebay for
$30.00. It was very easy to change. It took me
about an hour this past Saturday to do it. The store
that I bought my regulator off of had plenty of brand
new regulators.

Try this link for some help with this , has a few pics.
