I have a 1992 Toyota Camry XLE V6 and I am having some water leaks in the trunk. I checked the lining around the trunk (the PVC tube and the plastic tubes on the left side of the trunk) and everything seems okay. I'm not sure what the problem is or how there's water going in, any suggestions?

 

There should be rubber weatherstriping along the trunk liner, have you checked that? Pull your trunk carpet, etc out and look for any corroded area in the metal. Also, check where your tail lights enter, sometimes it might leak through there.

 

Like said it might be leaking around the lights or weather stripping. Remove everything from the trunk including the bottom mat,Get a good flashlight a trusted helper,a garden hose and climb in have helper spray water around all seals lights etc while you look with the light.Look on the bottom of the trunk under spare tire should be a rubber plug . (make sure your helper has the key). dont worry you will have plenty of air to breathe.Take your time. set up a way to communicate were you want water sprayed.

 

I had the same problem with my 1988 Toyota Camry LE. Changed the rubber moulding around the trunk, lifted the rubber seals below the spare tire and drained the trunk all to no avail. The problem turned out to be a rubber tube, leading from somewhere near the roof of the car. It passes down through the trunk on the right side and is supposed to go through the bottom.
It is some kind of drain. On mine, the tube had worked loose and the water, wherever it was coming from, just drained into the trunk, getting everything wet and turning the spare wheel well into a pool.

I found the tube, pushed it down through the hole and secured it with a clip.

Trunk has been as dry as a bone ever since

 

Thanks guys. I will look into all of your suggestions and post back with results whenever I get the chance.

 

I recently purchased a used 94 Camry which appears to be in very good condition for a car with 123k miles. But, I found water under the spare tire also! Two of the plugs were opened, so I thought water had been spraying up through those holes when driving on wet roads. So I put those plugs into the holes. After a couple days of rain I thought I'd take a look in the trunk...Good thing I did! At least a half inch of water was there under the spare tire now! I pulled the plugs and dried the trunk out. I inspected all the rubber seals around the trunk and rear window, but they all look fine. None of the carpet is wet,except when the trunk door is open and water drips off from that.
I've been searching the net for about an hour looking for an answer...I hope I get the same results you did!
I found that tube, on the right side of the trunk just like you said. There was a pool of water under the tire jack and the tube was not in the hole that leads out of the trunk. I put it through that hole and found a small nylon clip that fit around the tube on the outside of the trunk to hold it there. If that clip doesn't do the trick,I'll get a better one. This is a test.
It's amazing to me that after all the very good engineering they have done on these cars, they would put that tube right where it can be hit by the tire jack! And there's no restraint to keep it from coming loose and spilling water into the trunk.
