There is moisture in the carpet pasenger side that may extend to the back seat. I can not see a source.
A/C condensation? Thoughts?

 

It sounds like your a/c condensation holes are plugged. I'm going to find a thread with pics courtesy of okdiscoguy and link it for you. hold on.

 

Scroll down and read the thread, I have to do the same thing, just been lazy about it. Very common issue.

How do A/C drains get clogged? That makes no sense to me!

 

Particulate matter, dirt, dust, calcium and other particles in the air mix with the condensed water as it drips from the condensor to the weep hole. I think rover should have made the weep hole a bit bigger, or routed it differently!

 

Thanks. That fixed it.
