After the past few storms the carpet on my passengar side rear was wet. I did not see any problems in the seals around the door and T-tops nor did I see anything on the headliner or door panels that looks like water damage.

Any thoughts on how I can find the leak?

 

did you check around the hatch seals mine leaked there. i hope that helps you some

 

i had to find a leak from inside my car once and did that by getting in the car and pulling up the carpet, etc. of the suspected area and had the wife run the water hose over the area til i found where it was coming in at. don't take for granted that it's entering from that particular area, though. even though mine was coming in at the firewall area, it was because the sealant near the hood hinges just below the windshield was leaking. hopefully your leak will be easy to find...

That could very well likely be your heater core

When I bought my first 'maro my heater core was bad (leaking like a beach ) and needed to be replaced.

Replacing it isn't too bad except my one word of advise is to spend the extra couple of bucks and get the fitted hoses from NAPA or somewhere instead of the 35 cent-by-the-foot heater hose. It makes life alot easier.

 

There are a few things to check. First thing is remove wipers and then remove the black plastic cowl screen. Down inside is where your fan draws air. Check the drain to ensure water can run out. If the drain is plugged the water will run inside where your fan is. If the drain is operational check your A/C box on the firewall. There are seals that go between your firewall and your air/heater box and these can fail and cause water to end up on the floor as well.

 

Thanks for the tips. I just took a good close look, the passengar side door seal is pretty shot. T-tops and rear hatch look good.
