Western Star Truck Issues And Fixes

I was at my shop this weekend changing oil in mine, my daughter was vacuuming the truck, asked what I spilled on the passenger floor board. Nothing, the only thing I keep over there are an extra pair of boots and a can of glass cleaner. Had to be water from somewhere, it was colorless and oderless.

 

If your front pass side window leaks the water ends up on the floor under the floor Matt.

 

If they get real close to it with a power washer it will at the top, otherwise for rain it never does, at least not that I can see.

 

Always check the drain for the A/C , if it plugs it overflows and spills on the passenger floor.

 

Like cetane said, that is the area for a/c drain backups. If you put it on recirc, you can see the drain hole and if it's backing up through the metal screen

 

The back sleeper wall is fairly thick already. You can try some Dynamat, not sure how much it would there. The fiberglass upper portion would be the best bang for the buck IMO as that portion is pretty thin. If you have water coming out of the headliner, I would be resealing any roof accessories FIRST. There is a small interior aluminum channel that runs around the perimeter of thr sleeper where the fiberglass cap is joined to the sleeper. It can make trouble shooting rear leaks difficult as any water will gather in the channel and come out at the cab sleeper joint. Hard to explain, but if you've pulled your interior, you understand.

 

Well it's not the trucks fault. It's the people who put them together. When both my trucks were new I took an hour of time and fine tuned the striker and door latch on both my trucks. They close like a Lexus now.
The trucks are only as good as the people who put them together or work on them at the dealerships.
Even though my trucks are or were under Warrenty I chose to just fix the small issues myself. Everywhere you go no one gives a ####. It's very rare to find quality workman ship now a days.
Most all the problems are not the trucks design but more the idiots at the plant throwing them together and pushing them out the door.
Then it's the dealerships responsibility to catch the problems in there PDI , but I've yet to see that done properly either.

All this having said , I'd order another in a heartbeat.

 

Ran the ac all afternoon, stopped a couple of hours ago for fuel, drain tube was dry as a bone, just checked it again, not a drop of water in the tube at all.

Ran a wire up thru it from the outside and nothing, went inside and pulled the tube off the plastic nipple, (a real frigging joke how that's ran) tube is clear all the way thru, ran the wire up into the nipple and something is stopping it, not a drop of water on the wire either, or any dirt. Not that there should be any as the truck only has 64k on it.

There is a wet spot under the floor mat, but not a single trace of water from the floor mat to the firewall. I'm stumped.
