I verified the 3rd brake light is dry behind it, the bulkhead connector to the door is dry, the rear floor is dry.  The only evidence is drivers pad and carpet are soaked and water is in the wiring trough near the pinch weld of the door.  The nuts holding it down are rusty, so water has been there.  The wiper cowl drains are clean.  I bought this truck used, so i have  no idea on glass.  I pulled the bed liner out to clean out the bark under it,  he must've hauled wood, so back glass replacement is possible previous owner.  Cab vent?  Can't see it, behind trim.  I have the door sill trim, the kick panel, and the carpet pulled back.  No pics at this time.  Raining hard right now.

Sunroof?  If so, the drain for it (runs down the A-pillar) could be plugged

Sit in the truck and have someone spray water on roof, windshield, etc and see if you can see where/how the water is getting in

 

Here's a link to another post in case it gets more answers

I had wet carpet in my '06 Avalanche. I took it to a glass shop and the cleaned the Sun roof drains, no more wet carpet. Your windshield could be leaking. The PO might have installed a new W/S, if you don't know how to do this (it's not hard to do but you have to know how) it's easy to mess up. You could have a glass shop reseal the W/S, I would pay them to fully remove and reinstall it though. They might want  to chase the leak (if it is indeed in the W/S) but I recommend cutting to the chase and have it fully removed, the opening cleaned along with the glass. I'd be thinking about pulling the carpet come summer time, hang it up and pressure wash it and let it dry thoroughly; or hey, you can replace it, there are many sellers.

I was going to say windshield as well, thought I commented but guess not.

I had a windshield leak that led to my passenger floorboard getting soaked. When I tried to find it myself I never could find any drops of water at all. Just replaced it because I had cracks in it and it was only $125. Turned out to fix the problem.

                                                                                    No Sunroof or cabinets.  If the cab vents leak does the trim route it through that door seal.  If no that must be over runningthdoor seal.    Too cold to hose it now.     ice on the ground and below freezing.  What sucks is I can't see the seal in the truck.      When it gets wet  I've been using my carpet extractor  On the pad and carpet.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
