Open up the door and try to move it up and down. If there's a movement the door is loose. If that's the case, tighten the bolts on the hinges and then drive it and check for air leaks around the seal as the loose door means that the initial alignment is has been disturbed. Check the gaps around the door on the outside while it is closed to make sure they're in uniform width. If the door is not loose, try silicone lubricant on the rubber seals. Hope this helps.I have noticed a noise from my driver side door. While driving the door seal is making a very annoying noise. It sounds like the door is loose and shaking causeing the door seal to squeak. Has anyone had a problem like this and come up with a way to fix it cause it is driving me crazy.
