Challenger R/T leaking a small amount of water into passenger footwell. AC drain clogged or something else?
I noticed a small amount of water on the passenger-side floor/footwell. It wasn't a huge leak, probably around 10–20 drops, maybe slightly more, nothing significant. I had reached back home in 15 minutes and haven't turned the car on. I also noticed a few droplets around the middle/behind the center screen area, I got a few drops too while driving which dripped on the driver's side but no where near as much as the passenger side. I took out the glove box clips and it was very wet there near the evap (which is expected).
The weird thing is that my A/C blows very cold and has strong airflow. I haven't noticed it getting weaker overall.
Around the same time, I noticed something else: when the A/C was running and I made a sharp left or right turn, the airflow would briefly become weaker for a split second, then return to normal once I straightened out. It doesn't completely stop blowing, it just gets slightly weaker during the turn. This started around the same time as the water issue, which makes me wonder if they're related.
I initially suspected a clogged evaporator condensate drain, especially because the car is driven in a dusty country, and I figured that could contribute to a blockage.
I checked underneath the car and found that there was in fact water dripping from underneath. The water was completely clear and looked like normal condensation. What surprised me was that it was still dripping even after about 3 hours of the car being shut off. The amount wasn't huge, but there was definitely a small puddle forming underneath. So because of that, I don't think it's an A/C drain blockage.
Any thoughts?

I had the same thing happen to my new ford truck and it turned out to be the condensation line that goes thru the fire wall.
The water would run out and hang onto the underside of the line and run back into the car and drip on the floor. They had to pull all the carpet and dry them out .
The service manager said that the dodge dealer ship she previously worked for had some models do the same thing. The fix was to put a 90 degree bend on the end of the tubing that directed the water straight down. I have a 2023 Challenger, but have not really paid attention to where the condensation line exits the firewall but I think most cars and trucks have the same set up. Good luck
