1999 TAHOE LEAK?

[PAULSON524]

Im new to the group but I'm not new to owning Chevy trucks. Im on my 4th Tahoe/Suburban now.

Anyways Im having a problem with my 1999 Tahoe leaking water somewhere at the back barn doors? I've replaced the rear door seal already and its still leaking. Has anyone else had this problem or have any idea where it could be leaking from?

Thank you for any help

Do you have the third brake light on yours ? If so check the light seal or gasket

Yes I do! I havent looked at that yet. Can you even by that gasket?

UPDATE: So I pulled the third brake light and cleaned it up real good and when I put it back on I used clear silicone all the way around the casket and around the top of the screws holding it on the truck... 3 days later after it rained again.... The back to the Tahoe is soaking wet and leaking still. UGH!!! Any ideas?? Please help!!

Sit in the back of your truck and get a friend to hit the back of the truck with a garden hose. Have them start low and work their way around the truck from bottom to top. Hopefully that'll help you identify the issue(s).

Cut down the foam seals that go around the metal parts that hold doors from swinging wide open. They sit on top of the rubber gasket that goes all the way around the opening. I trimmed mine and it slowed but didn't stop the leak because after years of being that way the main gasket was already formed to the foam, so I just bought a whole new barn door gasket from lmc truck and no more leaks
