Soooo you thought it was that sun roof drain issue didn't you? So did I. It's not!
Baseline: My driver's side footwell had a ton of water I saw on the carpet after a big rainstorm. Trial,error,lots of towels later I believe I root caused it to APillar plastic cover coming loose and water coming in through the plastic rivet holes. Other relevant info:
1. I had already cleaned + rerouted sunroof drains a few years ago
2. Checked all 4 sunroof drains again, working fine
3. Checked HVAC drains in center console area, don't seem to be a problem
4. Siliconed the crap out of the A Pillar exterior cover
5. Dried the entire area for weeks, wow does that foam under the carpet soak up water.
6. Water splash tests never resulted in large ingress of water.
7. And so I thought.... issue resolved!
But no, it's not! If I go back every day or so there is always a wet area in the center of the carpet, underneath only, basically smack under the plastic molded in floor mat in front of the pedals. No water in the wire loom tract by the door, no wetness on the carpet anywhere else but here.
Where is this water coming from??? Ideas, things to try? It's in front of the underfloor heater duct for the rear passengers, related? Condensation from the floor?! it's been a bit chilly in the mornings here in California. Or somehow sneaking down between layers of the carpet from the console, Heater core or something? Leaking front windshield? I can't seem to find a trail of wetness leading from anywhere to where I get damp foam insulation under the vehicle and its been happening for almost 2 months since original water ingress issue. Seems to happen independent of rain.
I'm out of ideas aside from A. living with a stinky wet car or B. tearing out the entire carpet and trying to find the source. Help please!
