motor seems slow going up and the window doesn't always seal when at speed. I have considered flexing the upper door/window outward to where the glass appears to want to go but will wait for some responses

Try lubing the run channels with some silicone spray, do not bend the door frame unless it was damaged before.

I would have to say that your window motor/regulator may be going out. They are sold seperately or as a unit. Buying the regulator and motor as a whole unit is much easier to install and it will save you the time and the effort if doing it yourself. Also, I would replace your window guide tracks as well. With your window going off track it puts a strain on your motor and makes it very weak.

Cleaning the window on both sides, and using Rainx helps to be less resistance.

Thanks I'll try the rainx. I forgot to say that this is an '08 with only 18k on it
