The plastic clip that holds the window to the regulator broke while I was putting my window up in my driveway. I found this out after taking it to the dealer. They tried to sell me $400 window plus labor because they don't sell just the plastic part. I saw someone makes aluminum replacement clips for this problem so I bought one and it worked really well! It was way cheaper than paying to replace the whole window. I bought the part at bluemooseegineering.com. I don't really know what else I would have done because I couldn't afford to fix it at the dealer.
