Got water in my sparetire compartment. Do you know how it gets in &howtodrain

Tar Heel Person>>if you have a wet/dry vac,then you can vacuum it out.may be a plug under the tire,idk.if you have neither,get a large cup or small bucket and dip it out,or go to Autozone a buy that cheap hand held Siphon Pump and pump it out through that tube,by hand.as far as the leak,get in the trunk with a flashlight,while some sprays/runs water over the trunk/rear windshield area to see where the water is leaking in at.
