hey peoples i need to adjust my door window its going up far enough i adjusted that but when the door is shut i go to wind the window up and it goes the wrong side of the rubber and gets stuck so have to wind it down and push the window accrossed to get it to go up
The window does seem to wobble about a bit has something worn out /broken or is it just a matter of adjusting it if it is how do i do it please help me its getting abit annoying now lol
Thanks in advance

there are quite a few adjustments you can make, the regulator has a few slotted holes, and the rear channel has 2 bolts that sit in slotted holes at the bottom of the door. loosen everything off and move it around till you are happy
