Well guys, upon cleaning out my car the other day, I noticed that the floor pan on the passenger side of my 95 civic sedan EX was wet. Smelled like old, stale water (mildew, whatever). Went to investigate further tonight and discovered that the rear passenger floor pan was VERY wet after a storm this evening. I want to stop this right away but I'm not sure where this could come from. The car wasn't driven during the storm, it sat in the driveway.

The puddle doesn't extend all the way to the front of the floor pan so I know it's not the heater core or hoses, Those have all been replaced in the last few years.

I checked a diagram for the sunroof, and by the picture it should drain out the front passenger side and rear driver, is this correct? I know for sure that my front drain comes out on the driver side behind the fender. So does that mean my rear drain is on the passenger side?

 

gut the interior and take it through an automatic car wash.
Watch where the suds come in, and start pulling panels.

 

I believe there is a tsb about body seal not always being done completely at the factory and the leak is almost always on the passenger side.

If I can find it, I'll post it here but I'm 99% sure that's your issue.

Here it is:

Thanks, I just saw this. I read through the article and that TSB indicates that it would come in from the front of the car. I guess the only way is to tear the interior out. Not something I'm looking forward to. I've already had to put it back together from a bare and empty cabin once before.
