Drivers Window Moving Up and Down Rapidly On Its Own

[RickyBobby]

Hello:

When the drivers side door is open the window goes up and down rapidly, moving only about 1/2" or less up and down from the closed position. It does this randomly, sometimes it will keep doing it while the door is open, sometimes not at all. I took it to the dealer soon after the problem originated (at the tail end of the warranty), but they couldn't replicate the motion, or find a problem. They said if it continued, they would still warranty it, but I don't want to take it in yet since it is hard to replicate, and it only does it from time to time (although it has definitely been getting much worse over time).

I tried the manual reset method that I've read on the threads here, with no luck (the problem I have seems to be different since other people describe a window that keeps lowering (not the same as my problem as described above)).

Any suggestions?

Thanks in advance -
