Thread: passenger floor gets wet during rain

Ive searched but cant find anything b13 specific. I noticed when it rains my passenger floor gets wet. I havent had a chance to look into it yet. Just wanted to get some ideas before i get started. Im thinking some kind of drain is clogged?

Do you have a sunroof?

yes.

drop the headliner, the moon roof train tubes are easy to find. blow them out with some compressed air.

I had to do this to my last G20. Not sure about the drain holes on the B13, but the G20's front drains are accessible with the sunroof opened. Just used one of these to blow through after pouring some water down the drains, worked like a charm...



And didn't have to drop the headliner either.

I'm guessing its not sunroof related.

There's a TSB where they put a metal plate over part of the cowling where the fan/HVAC takes in air. I've put this plate in two SE-Rs to fix the 'water on passenger floor' problem. You can find them on most 91-94 Sentras in the pick-n-pull for $3-5.

You have to pull the wipers and the plastic cover that sits between the hood and windshield. Some of the metal plates need trimming with a dremel tool to fit. Use gasket maker to seal it together. Your AC/Heat/Fans will still work the same as before but no puddle on the passenger side floor.

This happens only when it rains. So im guessing is some kind of draining issue. I will blow out the sunroof drain hoses and then see if it still happens.

Of course it only happens when it rains. That's where the water comes from

Lol Uh duh only when it rains

I was reading up somewhere where the said something about condensation when using the heat/ac...but i dont think thats what it is.
