Peterbilt 579 floor wet in sleeper

My 2018 is leaking in the sleeper as well. Peterbilt of little rock replaced the door seal and adjusted it but it's been raining all week and when I picked it up it still had water in the floor. I'm hoping the weather clears up by Monday so I can clean the inside up and dry it out and have them silicone around the vents and see if that fixes it.

 

I know 2 out of 3 2019 Pete 579 that a company has leaked badly and they gutted the interior to fix the leaks .. shop told my buddy it’s 1 out of 6 that leak I don’t know where exactly but it was in shop 2.5 days .. I drive the same and mine is dry for now

 

You will love it here in Arkansas. When it's raining it's too stormy to repair the roof today. When the sun is out, the roof is working great. =)

I consider this a dealership fix. Maybe even a warrantry. I had a car that did that when the factory failed to put a seal on the antenna feed wire at the firewall. Cost about 5000 in interior work versus a 7800 dollar retail vehicle under warrantry.

 

Mine was at peterbilt of little rock last week and they replaced the door seal and adjusted it but it's still leaking. Not sure if I should take it back or seal around the cab vents

 

AwilAw

Awhile back I drove a '17 579, and on one trip out to Mass. it rained 8 days straight and the carpet in the sleeper was soaking wet, shop said it came from some vents, they sealed them up. I guess it's a design flaw with Pete.

 

Peterbilt 389, 386 owners. If you have wet carpet floor. Water is coming from the windshield wiper arm which slides left and right every time you turn wipers on. There are 2 bolts on each . From outside take them out and seal those chrome oval looking metals. Even if your truck is brand new seal them before water gets in and starts to stink. Then you have to take seats and everything out to take the carpet out and dry it. Its a factory problem. They dont have any kind of seal or casket on them . Just silicone them from outside. Took me one week of spraying everywhere and driving half of my dashboard apart. Thats the last place that anybody will think of water can get in.
Picture show's where the water comes in from inside under dash view.
I have 2 friends that have 389s . They had the same issue.
Every 389 or 386 owners if you see this post dont even think twice check under your rubber floor if its wet (99%) its coming from wiper blade tube

 

Does anyone know the part number for the carpet in the sleeper on the 579?

 

This is an old thread but Peterbilt should have it with the last 6 of your VIN

 

Have you checked to make sure the A/C drain for the sleeper isn't blocked and overflowing into the sleeper. OBTW the fridge does create water when it's defrosting or turned off.
