No not in the channel. But I think the water may have leaked down the channel, onto the floor. I had rusty floors like you as well. But ever since I took the cab weatherstripping off, silicones around all the little holes, and put the weatherstripping back in place over the silicone, no more wet floor. But that was just my case. Thought I’d share it with you incase you were still leaking some water and couldn’t figure it out.

Thank you for the tip!

Friend of mine used to do windshields, he's gonna swing by tomorrow I think and take a look at it. I'll report back what he says.

I had the hood open with the AC running and there was water coming out of what I assume is the back side of air box. I'll snap a pic of what I'm talking about tomorrow and post it up.

Hope everyone is having a great weekend!

Other thing to check is drain line from condenser. Min plugs up occasionally. And wet carpet on passenger side. Only happens when hot and humid.

No update on the leak yet.

However, I did pull the trim panels off the driver and passenger front doors to stick the butyl on and out in some old Sony XPlode 6" speakers I've had sitting in the basement for the better part of a decade lol. It's getting better, but now I think I'm hearing wind noise from the windshield lol.

Say - would any of you gents with air seats happen to have a part number/ name/ source for the fitting at the back of the cab for the air lines? Mine is leaking on the outside half. I already cut a half inch of hose off and reinstalled. No dice. I also need to replace the T inside, drivers toggle and figure I should replace the lines that are under the floor mat as they're kinda tight now that I trimmed them to eliminate leaks

Thanks!

Thank you!

I still need to do the back doors yet.

It's definitely better than it was. Not when I shut the doors it sounds like I'm shutting them on a nice pickup truck

Well, not sure if it worked, but I did do some cleaning. The little flapper located under the condenser that I believe is the windshield drain was blocked up. I vacuumed that out and then removed the blower (3-5.5mm screws) and found more leaves sandwiched between the condenser and the housing. I tried to move the computer stack by removing a bunch of the 13mm bolts that hold the tube frame in place, but no dice. I then removed 8 or 9 of the 5.5mm screws that hold the 2 blower housing halves together. There are a few buried under the firewall that aren't practical to get at and there is another that secures on of the AC lines to the housing. There is also a tab that needs to be depressed (it's kind of under the blower fan hole). I was able to get a long screwdriver in between the two halves and used that to "shake" the outer section and a lot of debris fell out. I'm sure I didn't get all of it, but enough that I'm glad I went through the excercise. I was able to get a single 14ga solid wire into the drain that comes through the firewall about 3 or 4 inches. Afterwords I got my finger wet and while the AC was blowing, it felt like cool air was moving past my finger when placed directly in front of the drain. Not a lot, but I wouldn't expect there to be from a drain.

Now, I let the AC run for about 15 minutes and there was a decent amount of condensation coming out of the bottom of the big housing where a hole is, but nothing from the firewall drain. 2 questions here.

1- can anyone confirm is this is normal?
2- does anyone have a hose of some sort coming out of the bottom of the housing? The condensation drips right on a bunch of the wire harnesses and there are some connectors that I can see potentially getting damaged by this.

Insulation update-
I haven't gotten to the rear doors, but I can confirm that it is better than it was. I was able to listen to the radio at a reasonable volume and my ears aren't ringing after a 5 hour drive, pulling the camper. I think that the aluminum flat bed with headache rack while beautiful, is part of my problem. There isn't anything between the frame rails and there is a pretty large, but thin sheet of diamond plate on the lower half of the rack. I plan to lift the bed and put rubber between the rails and when I do so, either etch and spray the backside of the diamond plate with bedliner or the insulating spray I have, then maybe top coat it for UV protection or attach the butyl that has a black backing. I also need to get up around the firewall in all the big cavities I'm thinking, to reduce the noise from the front tires. Still undecided, but I'd really prefer it be a little more quiet than it currently is.

Thanks for checking in!

I really like the massive reduction in road noise when having a truck bed Line-X sprayed.
