First look on top for any trim that's sticking up and catching the wind.

Next, check the seals. You can do that by sticking a dollar bill in there then closing the window. The bill should not pull out easily. If it does, look for a weatherstrip that is deformed or mispositioned. Usually there is some type of seal that has a groove to slide it onto the metal pinch weld of the roof panels. You can sneak in a piece of electrical wire into that groove so the weatherstrip doesn't seat so deeply. That will push it closer to the window frame.

There is also a powder we use to tell how well a rubber seal is sealing. I know the Chrysler dealer's parts department has it. Other dealers will have something similar. You spray it on one surface, slowly close the window with as little pressure as possible, open it and look to see where the powder didn't transfer.

If the window lifts up to open, look for an adjustment on the latch to pull the window frame down tighter on the rubber seal. Often you can identify that by tugging and twisting on the window while a helper drives the car.

USING WIDE (BLUE) EZ TO REMOVE PAINTERS TAPE, YOU CAN COVER YOUR DOOR SEAMS-WINDOW SEAMS--TRIM---EVEN SHARP EDGES ON A LUGGAGE RACK......DO THIS ONE PLACE AT A TIME

IF YOU DO THIS, DO LIKE JUST THE ENTIRE DOOR SEAM----IF THE NOISE SUBSIDES, YOU KNOW YOU ARE IN THE RIGHT AREA, START REMOVING A LITTLE TAPE AT A TIME THEN RETEST.....FINALLY YOU WILL FIND THE PROBLEM SPOT

CRAWL THRU THE PASSENGER SIDE, TO GET IN, IF YOU HAVE TO

IF THE NOISE IS STILL THERE, MOVE ON TO THE NEXT AREA TO BE TESTED....AGAIN, IF IS STOPS....START REMOVING TAPE TILL YOU FIND IT
