There is a switch inside the door actually there are four one for each latch the upper limit (window closed) and the lock.
You can actually roll the window out by "closing" locking each latch then the window will roll up or out of the door.
WARNING YOU MUST SUPPORT THE GLASS IT WILL BREAK OUT OF ITS MOUNT WHEN FULLY EXTENDED!!!
Then you can work inside the door cavity.
It almost sounds like it just needs adjusting.
This is also how you can easily repair any broken defroster wires.

Good luck
