I have a leak in my trunk and can't figure out how to find it I have tried opening the rear seat and sitting in the car watching and saw nothing but I still had water in the spare tire. Any otheri deas where it could be coming from

 

hahahah yea put a friend in there...

nah you test them the same way you test the seal on a refrigerator door.

Most people use dollar bills but you can use something else ... insert it in the trunk and pull it free... if it slips out real easy then you know the seal is leaking in that area.

Another way is to place baby powder on a clean surface...

honestly the stuff that is used comes in a can and its talc powder so baby powder is much cheaper...

dust the area blowing it off your hand ... little goes a long way.

Moisten the seal by wiping it down with a paper towel

close the trunk and open it.

there is your leak

 

thanks
