I have only had this issue three times now. At sonic the other day I pulled up and rolled down my window to order. After ordering I attempted to roll the winow back up. Once It got to the top it, it stopped and proceded to go back down to half mass. I tried to roll it up again three more times. Still the same annoying thing. So I opened the door and shut it; thinking that it wasn't fully shut. The window continued with the same procedure. So I shut off the car and took out the key. After putting it back in the slot in the on position with the motor off it finally stayed up. Any Suggestions?

 

See the "Driver's Door Window Dipper" thread. Looks like window motor replacement might be in your future. Good luck!

 

20008 MC- Same happened to me tonight. No more auto up and when it manually reaches the top, down to half mast it goes. Another dealer trip...
