Chrysler Crossfire leaky roof stemming from liftgate grommet on chassis

Get yourself some clear flowable sealant (either automotive or household type sylicon sealant) and seal the lower portion of the rubber boot grommet.
The part itself itself is replaceable, but you will have to replace the entire wiring harness for the rear hatch and trunk. And it is not an easy job.
Just seal the lower grommet to the frame. If you push it down right it will "click" into place into the frame. But yours night be broken and wont click either.
Hope this helps, and let me know if you have any other issues. Crossfires are my babies, and I have many friends I constantly help fix em cheaply.
No cause there bad cars, just chrysler branded with mercedes pricing. Lol

Hi there JCNINJA636

Thank you for your tips above - they worked a treat!

No water ingress since a year ago now and I just simply siliconed around the grommet, clicked it into place and then smoothed it off with my finger.

I now have a different problem. What do you do when the tailgate rattles when fixed into the closed position via the latch.

Normally, when the tailgate is closed (in any other car) there is no rattle, however with the crossfire, when the tailgate is closed and I'm driving, it rattles constantly - can you help please, or is it best to get it checked out and have the locking mechanism inspected?

All help is much appreciated, thanks in advance.
