Go to there home page and follow the interactive prompts. There is a left and right motor assembly and regulator. Prices rage from, "call" to $75-101.00. IMO I'd just get the whole darn assembly motor reg. and all....Most will gladly ship it to you..

For permanent repair suggest the following. Remove the window and glue/epoxy the tabs with Weld It....let the mixture set til starts to thicken and use masking tape to keep Weld It from spreading out too much from the tab.

The weak link, at least in mine, was the nylon bracket that supports the window support...(pardon the inexact nomenclature) This bracket slides on a vertical brace that has the approx. same semi-ellipticle curce as the window. This nylon bracket has a ridge or lip on both sides of the brace that hold it on to the brace. On mine this nylon bracket just wore out from sliding up and down and would pull off the track, once off the slider the windows only support was the cables. The trick is to get the nylon bracket to follow the vertical brace as the window slides up and down. I did this with couple of small screw with oversize heads. The heads of the screws hold it on the track. I also used white grease to help it slide on its track too, but this way its alot stronger than the flimsy nylon bracket that just incrementally wears out going up and down...I should have took pics of this repair on both sides...Sorry I did this a couple of years ago and going by memory...apologize if I confuse you more than help

Good luck
