For those suffering from slow or stuck (or down) windows: now the clip itself is available for your car. OEM do NOT offer the clips for most models; instead, you have to buy the complete regulator at high cost. The 'symptoms' of broken clip: - window moving slowly - slight tilt of the window on one side when going up - need help by hand to go up - window moving up slowly and reversing/going down. Those are signs of a broken clip. Chances are the 2nd clip breaks (at which point the window stays down), or the window motor burns out.
