what's the best way to find where a leak is coming from?
my trunk has been filling up with water and i've really gotten tired of sucking it out with a shop vac.

EDIT: no clue why I typed truck instead of trunk... twice.

 

hatch ?

 

whined up the windows lol

 

Well a truck bed does fill up with water If you ain't got no camper Bud.... sometimes snow tooooo.....

 

check ur tail light seals... mine were bad, a few 8mm or 10mm bolts and take them out get new seals put them back in... what kind of car?

 

2000 toyota solara.

 

No Toyota forum? Does it get wet even when just parked, or only if driving in the rain? Remove the trunk lining, make sure the trunk is dry. If the back seat folds down, do so, then get inside the trunk with a light and have someone go over the rear window, trunk seal, taillights, etc with a hose and watch for source of the leak.

 

have someone run a hose on it while you crawl back there with a flashlight and check where its leaking.

edit: what he said^^
