2002 Envoy SLE...broken driver's seat....

Hi I have a 2002 Envoy SLE, I bought it new and milage is now about 81,000. A couple days ago on entering the vechile, I heard something break in the driver's seat. Now the left front corner of the seat is "drooping", I have the 6-way power seats and trying to adjust this will not work. Looking under it, I can see the adjustment arm (???) in this area moves freely up and down. Is this a common problem? Can this be fixed without replacing the seat? Any advice appreciated.

If you cant improvise by adding a nut or bolt that might've snapped or fallen out, then you're most likely going to have to replace the seat. You can always check Ebay or your local "pull-a-part". I would try to improvise something first though :)
