Its the regulator... I'm positive. Both my fronts did the same thing. I just got my driver side fixed at the dealer for $220 after tax. That's including parts and a new vapor barrier (I guess mine was f-ed from someone else taking apart my door before I bought the car). If you dont have $220 laying around, look into the DIY fix for them... that could be all you need. Unfortunately, my regulator was beyond the DIY

I would say check the motor. Mine goes down but wont roll back up. WHen I tested the motor it only moves one way.
