|Shrinking Door Weather Seals
If you've noticed water getting inside your Jeep® Grand
Cherokee®, or the road noise has gotten bad while
driving, take a close look at your weather seals around
all four doors.
What you're looking for is the little rubber strip that goes

weather seals for your doors. In the meantime, this
quick fix will keep your Jeep® Grand Cherokee® quiet
on the inside, and dry during car washes and
