i have a damp spot that keeps popping up under my passenger floor mat, doesnt smell like radiator fluid. it seems like just water. i have no clue whats going on!

 

Could it be condensation from the AC??? There is a drain tube that drains water from the coil to the ground and if it is clogged water will run onto the floormats and floorboard on the passenger side. Run the AC on MAX with the blower on HI and see if water is dripping down to the ground outside or is it draining in your vehicle.

Goodluck

where is this tube located?

 

It should be in the firewall below the evaporator core behind the accumulator.
You can also follow the hose up from under your vehicle to where it goes into the firewall.
If it really is the drain is clogged you can you a zip tie and clean out the line and elbow of that drain line to clean it out.

Hope this helps

Could also be rainwater if it's been exposed to rain. It's pretty common for windshield leaks to run down the firewall and onto the floor. I've also heard of water puddling under the cowl because the drains are plugged, and then leaking into the car.
