Recently installed oversized tubing on the front drains from A pillar to grommets on both sides on my 10 h3t.Looking to do the same for the rears.How do I access the rear drains? Can I access without removing the rear seats? Any ideas appreciated.

 

You have to remove the rear seat top & bottom, both side trim pieces and headliner to access the rear drain tubes on the H3T.

 

Thanks

 

PS: while you have everything off the rear wall. Sound deaden the rear wall. Makes a pretty big difference.

 

Good idea.I will dynamat it.

 

Update...removing the rear seats is not needed to access drain points on the T .Just tilt seat backs forward and remove the panel behind.Get a plastic trim tool and pop off while lifting up as there are clips on the top of the trim.To reinstal,l line up push pins and top clips,push down on top so its level across and seated then snap into place..very simple.Drain fitting are low in the cab corners facing the rear.Similiar to fronts but have no baffle to drill out.Therefore they are wide open.The fitting is a long turn 90 degree,longer than the fronts and mine were packed with sediment! Hot water cleared them well.Took some 00.60 weed eater line and fished upwards to the sunroof drain holes on both sides.Reinstalled drains and poured hot water with some distilled vinegar inside the sunroof channel and she was flowing like a river.Hope this helps others.
