gap between vert top and window
Some of the simpler things it could be are:
- bad weatherstripping - too compressed, rubber can take a "set" over time.
- bent bow pad - part of the top, bend it back
- door striker - does the door line up right when closed?
- glass felt - there are two small pads felt pads on metal plates that support the glass from the inside. You can see them under the inside strip but need to pull the door panel to get to them. They can be worn or out of adjustment.
- split door - sometimes the bonded panels seperate on our doors. $$$.
After all of that there is the alignment of the glass controlled by the door window hardware. Not simple stuff in there if you don't know what you are doing.
