Help, water leak inside cabin

Last week, I reach into the rear passenger floorboard to get a CD & find the carpet is soaked. So I remove the front passenger seat, peel the carpet back, remove the sopping wet sound proofing & found what looked like a couple of cracks in the factory coating on the floorboard, but no holes or rust.
After drying out, just to be on the safe side, I used an epoxy to fill & primed over.

Go out this morning after a hard rain last night & it's soaked again.

Given that it wasn't driven in the rain there has to be a leak, could this be a clogged sunroof drain line?

Thanks in advance!

Battery box has rusted through, most likely. Drips water on the passenger floor.

Remove battery, grind rusted areas out, and J-B Weld a patch over any holes. I sprayed mine with undercoating to prevent future acid damage.

Nope, battery box is in great shape & the carpet is only wet behind the passenger seat in the floor.
None of the carpet is wet around the door & nothing around the sunroof. Also, the rear hatch has a new seal.
Add to it that the car is parked on a slight incline & that is the high side.
Headed to San Fran early Friday for 6 days & would like to take care of this before I leave.
So, your help would be greatly appreciated!
Off to soak up some water...

Likely culprit. Either clogged, cracked or bad sunroof seal.

or a bad rear hatch seal (maybe...)

Battery box leak (for me atleast) only affected the front passenger footwell.

I'm going to try the air compressor & see if I can clear it.
Sunroof seal is in good shape & the rear hatch seal is new.

On a lighter note, I went to the local car wash to vac the water out.
As I finish, I look up & parked right in front of me is a Silver 924!
So, I met Bill & his 1977 924, over 300,000 miles & still rolling!!


Amazing how one thing can turn a crappy day around!

Ok, blew out both drain lines, didn't seem as though they were blocked.
Maybe it will do the trick.

try running water down the drain holes will make things a bit wet but at least you'll know whats causing the leak!

Hey Procon...had the same problem myself but had some good advice from other members of this post...I bet the car is parked on an incline nose up...rainwater collects in the battery box and drains into the passenger side of the passenger compartment...because the car is on an incline, it settles on the floor behind the passenger side seat...solution to keep it dry is to park it nose-side-down on the incline (back it up the incline)...that way rainwater will go down the windshield, into the battery compartment and drain out the drain holes in the front...

Nope, nose down.
Plus nothing is wet in front of the seat, just behind.

Going to find out tomarrow with help of my little bro & a garden hose!

Check the seal around the door. Mine developed a seperation at the top next to the rear. It would let enough water past to dribble into the back foot well. New seals have their gaps at the bottom.

It's your Sunroof.

Take weed-whacker line and run it through the drainage holes along with HOT water and see if you can knock some crap out of the drainage lines.

Also, make sure the sunroof is closing all the way. The adjustments could be off, and you may need to have it readjusted (PITA) or just go with a manual sunroof conversion like I did when this heppened to mine.

And yes, my battery tray was in perfect shape too - everyone just jumps to that conclusion for some reason!

I'll give the weed-whacker line a try, it's a manual roof & locks down tight.
Either way, I'll find out in a few.
Thanks!

Rmills944 thanks for the weed-whacker line trick!
All four drains are working, with any luck that will solve the problem.
Find out when I get back from San Fran.

Yes, so you know my roof is a manual roof. If you search that topic you can find out the details on a manual roof conversion. If you can't find it, PM me for details on it.

Id' bet on the sunroof seals. Previous owner decided to save money on my 83 & used the top seal in place of the bottom seal. Looked fine, but leaked all over when it rained. Depending on how the car was sitting in the slopped driveway of the PO determined where the water pooled. Ruined an entire carpet set.. Since I replaced the seals with correct, no leaks,,, unfortunately the stains are in the carpet (light brown) for good... maybe next season I'll get around to replaceing it.

Lower sunroof seal... trust me...

its been raining in daytona for the past 2 days it seems, and i also noticed some water inside of my cabin. Front passenger side, under the floormat. I have already fixed the rust hole in the battery box that was present when i bought the car. The drain on the battery box was a bit clogged, so maybe some water was making its way through the repairs i made? Any other ideas of where the water could be coming from?
