Hi guys,

Have a pretty annoying issue, water seems to be gathering in my boot. I've taken the lining out and sat in the boot while someone poured water all around with a hose.

The issue is the two vents on either side of boot(see pictures for reference). I believe they serve to maintain cabin pressure/air flow.

I noticed the water was really gathering when the hose was sprayed directly at the taillight.

Has anyone had this issue before and know a fix?
Is water even supposed to drain through the taillight and run past these vents?

Thanks.

It sounds like water is entering through the taillight seals or ventilation system in your boot. Check if the taillight seal is damaged and reseal it if necessary. Also, inspect the vents for damaged seals or blockages. Ensure there are no clogs in the drainage channels around the tail light. Fixing or replacing these seals should prevent further water ingress. If the issue persists, consider a professional inspection.
