open the rear hatch.....
then remove the panel that cover over the taillights on the interior...
reach to the corners behind that and there should be some tubes..
kind pull them out and there will be some black rubber plugs on them...
get a bucket and stick the end of the tube in the bucket in case of any clogged water...
plull the rubber stopper things out and clean them out with warm water...
then ( i did this) get a coat hhanger (metal) and make it long and straight....stick it up there and then twist and twirl it to clean the tubes...

when done replace the tubes back in the drains (plastic tube from where the rubber tube goes into) if thsi is not done u will have a very leaky trunk/cargo area...

if u have any more Q's hit me up AIM: Smittylax4
