My passenger side widow isn't going all the way up. Only noticed when it rained and there was water accumulating at the top seal inside. The gap is minimal and not real noticeable from the outside. Didn't notice it when I bought the car. Easy adjustment?

 

"...easy adjustment?" Yes and no... anytime there are electrics involved... it could be as simple as reprogramming the upper and lower limits of your window, or it could be as complex as taking the door card off and having to fiddle with the motor assembly and or the window lifter...

When you open and close the door does the window auto adjust? That is when you open the door the window should drop about half an inch, and when you close it if goes back up? If the answer is NO, then first try resetting your upper and lower max programming...
If is does, maybe your window lifter needs to be adjusted, it may have moved, for that you will need to get into the door.

Best of luck.

Motor on!

Check the adjustment on the window, you can finely adjust them from the gear nut where the glass connects to the window , also you can reset the window :
