YJ Hard Top Wind Whistling Noise

Jeff, I had this problem too but on the passenger side. It turns out that the triangular vent windows on the full steel doors don't seal as well as they used to and they create a fantastic high pitched whistle.

By shimming the point where it closes on the frame of the window may help it seal better and stop the jeep from whistling it's tune.

Hope this helps.

I had a problem in this area and it turned out that the weld was broken at the rear of the door, at the bottom of the where the vertical part of the window frame meets the door. If this weld is broken, the upper window frame won't push against the weatherstripping and seal right. It gets worse when you turn on the heater fan, because the inside air pressure pushes the frame out further.

Check your frame, if the weld is broken, I can email you a photo of a 25 cent fix.

Hello Jeff,

I checked to see if it was leaking around the vent window like the previuos reply suggested, but it is coming in above the door frame above the window. I did have to have my window frame welded a few years ago so maybe it isn't mounted at the correct angle. I would definitely like to hear what your fix is though! I was wondering if the upper door hinge pin could be bent in a bit???

My guess would be it was welded at the wrong angle. My fix can be found at

I used a #10 stainless steel screw. I drilled a clearance hole in the door edge, and a hole the right size for a 10-32 tap in the window frame, then tapped the frame. Using a serrated lock washer to make sure it wouldn't slip when the door was closed, I adjusted the window frame so that when the door was closed there was pressure against the hardtop frame. This fixed the problem; the screw has been in place over 1 year and has been working fine, no wind noise leaks since then.
