Water in boot of Corolla 1991

[samothreesixty]

Since we are getting into colder weather i have concerns of the water leaking into my boot. I have located where it collects but i can not find the source of it. Wondering if anyone can offer any advice that would be helpful. Thankyou

Here are the pictures i have taken of it. The water collects at the darkened section of the zoomed in picture.

Either rear window seals or rear light seals probably, same issue with my Astra, the seal on the light cluster has gone.

Exactly what 'Astranut' says above - however the way to pinpoint the leak rather than guess is to enlist some help - one of you in the closed boot with a strong torch and the other on the outside with a hosepipe - you will soon find out what the issue is

Hi, Another way is to lay or tape newspaper over the surfaces or puff talcum powder about and it will show up the water tracking.

Thanks. I took your advice and the water seams to be leaking in from the gap in the rear bumper. Where do i go from here? Should i be taking it off and checking?

Possibly a seam leak on the body panel or could be a body seal on any of the bumper brackets that protrude into the rear wing / rear panels in that case and you will need to remove the rear bumper to identify exactly what & where

Found the issue. Around this what i think to be a ventilation section any sort of seal it has is worn. The question now is what do i use to replace it and seal it up again? I will post some images of what it looks like as well.

I would take that off, clean all the foam tape off it, buy new foam tape, reseal and reinstall.
The other way would be to remove all the foam tape, clean both surfaces and then put a bead of urethane windscreen sealant around it.
