Hi. Down here in San Deigo, we just got hit by heavy rains - my 90 Toyota Camry was parked on the street, and the next day, while driving, I noticed a sloshing sound of water in the back seats. I found several inches water. A few days later, I attempted to drain the water out of the seats, but it always seemed to refill, like it had a hidden resevoir. I also found water in the trunk and drained it successfully. It's been this way several weeks. Otherwise, the car seems to function normally.

My questions are:
Do I need to see a mechanic or can I fix this myself? If so how?.
Also, what kind of mechanic would I see?

Thanks,
Barb

 

Back seat where one puts their feet?

Under the rear back seat cushion?

Might pull up the lower rear seat cushion and look for signs of water. Should pull up from the front.

 

I think you need some help from a pro... it require a lot of expertise to resolve the problem the seat seem to be in serious damage and the others as well.
