I'm afraid you will have to take the door panel off and check the mechanism. Something binding probably. I once took the panels off both front doors to replace speakers and one on the drivers side I had to do over cause I didn't do something just right.....forget what it was but easily corrected. the noise you are not specific where it comes from.....front, back? Probably the rear hatch making the noise. I have to lube mine every once in a while where the bumpers hit and the squeak goes away....hope this helps out.
