AC leaking into passenger floorboard
Hi all, newbie here. I wanted to pass on a problem I had with my AC. It was leaking into the passenger floorboard but I couldnt find a leak. After searching on here a little bit, I found some info that helped out. Turns out the leak was from the drain that protrudes thru the firewall. I thought it was the air box at first but the water was coming out of the drain and ran back to the firewall. I believe is seeped thru the firewall seal and into the cab. Once I put a hose on the drain, problem gone! Just wanted to pass this on to everyone in case they come across it. I love the board, great info!

Thank you for your help! REPS for that! I also noticed this is your first post, be sure to stop by the "newbie" section to introduce yourself and receive your fair share of harassment! :LOL:

I'm having the same problem. I'm not sure where this drain is though, any help or pics?

I found it, little black nipple sticking through the firewall underneath the accumulator/drier on the passenger's firewall. It's kind of hard to see but you can easily find it by feeling along the wall with your hand under the drier. I used a 1 foot piece of 5/8" inside diameter, 3/4" outside diameter hose and a hose clamp. This keeps the water from weeping into the cab between the metal and plastic housing and making it to the floorboard.

Glad you found it and you hit the nail on the head! It bugged me a lot thinking I was going to have to take the dash out and replace the evap. Thankfully it was a simple fix and like you said, a foot of hose and a clamp!

Yeah, can't really beat this fix with a stick, so darn easy and it only costs a couple bux. :D
