My car has been sitting for a week with snow on it. Today, all the snow was melted and before driving to the store, I grabbed something out of the back. I noticed it was wet. Really wet. So after feeling around the floors, the passenger carpets on both front and rear side are wet; drivers side front and rear are dry.

So - The car wasn't driven for a week because of snow. After it all melted, passenger side floors are really wet. The rear seems to be more wet.

Any ideas?

Thanks,
Matt

 

Sunroof drains.

 

Yeah, I thought of that. But I just replaced the sunroof and made sure the drain lines were good.

I guess maybe the door sills might be letting it in?

 

Sunroof drains, weatherstripping and possibly the seal on the rear window are the only things I can think of. Unless the water is getting in up front and running to the back somehow.
Look for stains in the headliner to rule out the drains.

 

Could the drains have frozen shut and didn't thaw in time to remove the water? I had water appear in the rear driver side floor board from a clogged sunroof drain hose.
