Got a weird one here. Last week, noticed a wet dog smell in truck. Lots of condensation in the mornings for a couple of days and some rain. Noticed the middle of my driver's side carpet (where my heel would go while pushing the brake) was damp but not totally soaked.
I pulled the channel covers, no signs of water in the channels. Pulled the A pillar and slightly removed headliner, no issues with sunroof drains, pulled rear carpet to expose rear cab vents, no signs of water. When I was working in the rear, drivers side middle carpet slightly damp but sides near door was completely dry. Passenger side is completely dry. Ensured drain tube of sunroof are draining properly. While everything was apart, used a hose to run water all over the truck, no leaks identified.
Any thoughts on how the middle of my driver's side front carpet is wet? I pulled the front carpet up and there is a plastic looking access panel that had some ever so slightly water build up in it which is located below this damp spot. This access looking plastic is sealed and everything looks intact. No rain for the past 4 days and I've used a blower to more or less dry the carpet out but it seems to continue getting damp in that same spot.
Sorry, brother. Let's Autobot this for the decrapicons on here. I won't tell you my similar situation regarding wetness so here it goes:
The fact that the carpet keeps getting damp in the same spot with no rain usually points to the thick padding underneath or the HVAC system. Here are the most likely culprits and how to check them:
1. The "Wicking" Foam Pad (Most Likely)
The carpet in these trucks is backed by a very thick, sponge-like foam sound deadener. If water got in previously (like during the rain you mentioned), using a blower on top only dries the surface layer. The foam underneath holds water for weeks. The "plastic access panel" you found is a floor pan body plug sitting at the lowest point of the metal floor, which is why residual water is pooling there. When you rest your heel on the carpet, pressure and capillary action wick that trapped water back up to the surface, making it seem like a continuous active leak.
Verification: Pull the carpet and the thick foam pad all the way up so the metal floor pan is entirely exposed. Prop it open and run a fan directly underneath the foam for at least 48 hours. If it stays dry after that, the leak was already solved or was a one-off.
2. Cowl Drains and Firewall Grommets
Water can pool in the cowl (under the windshield wipers) if the drains are plugged with debris. The water overflows down the firewall and sneaks in through the hood release cable grommet or the parking brake cable grommet. It drips straight down the inside firewall directly onto the heel area, completely bypassing the door channels.
Verification: Look high up under the dash behind the pedals with a flashlight for any vertical water trails or dried water lines. Pop the hood and clear out any leaves or debris in the cowl drains near the driver's side fender.
3. HVAC / Defroster Condensation
You mentioned lots of condensation in the mornings. Using your defroster automatically runs the AC compressor to pull moisture from the cab air. While the main AC drain leak usually floods the passenger side, some 2022 owners report water weeping out of the driver-side ducting joints when the system is running.
Verification: Run the heater/defroster on high for 20 minutes while parked. Reach up under the dash near the center console and feel the duct joints for dripping condensation.
4. Windshield Seal Defect
There is a known factory defect where the robotic caulking leaves a tiny pinhole gap at the bottom corners of the windshield. A standard hose test often misses this because the water has to hit it from a specific angle or pool up enough to enter.
Verification: Have someone spray a concentrated, high-pressure stream directly at the bottom driver-side corner of the windshield and A-pillar for a few minutes while you lay under the dash looking for drips.
Keep us posted, brother!
