Ok well I am lost and I dont wana go to the dealer as they just charge out the butt to tell u its this or that(not really) but I am having an issue with my truck thats new to me and concerns me. For some reason and this is just happening now never before, when I unlock my truck the time on the radio comes on(never noticed before so it may be normal) but sometimes when I unlock my truck the radio will come on and play for a second or two then shut off, and other times if u have it unlocked n unlock it again while inside the truck it will turn on n stay on till you physically turn it off( this is before the key even touches the ignition), now recently(including right now) when I go to unlock/lock the truck the time on the radio is still on and wont go away unless I take the fuse out, when I put the fuse back in the clock comes back on n stays on, even with the truck off and the clock is on you can turn the radio on and listen to it as if the truck is running normal but its totally off. Does anyone have a clue as to what the heck is going on as this is driving me nuts and I dont wana come out to a dead battery as I just got a new one a few days ago, like i said the clock itself is on showing the time whereas before it would go away when you open the door, also my drivers side door window switches are not powering down the windows am I ok to make the assumption that the switches are shot(the switches are for both the driver n passenger side windows) but the passenger side switch powers the passenger side perfectly.

Welcome to the wonderful world of Ground Faults.

 

 

My guess....and first place I would start is in the drivers door. Since the windows and radio are both powered when you shut off the truck for 15 min, and the door locks are always powered, I would say you have a couple wires shorting. Your 15min power circuit is probably getting powered from the lock circuit, and the ground is a broken wire on the window motor. A check for this....get the radio to come on, using the unlock button like you stated as a problem, and wait 15 min to see if it shuts off by its self. Than you know that its getting powered from the lock/unlock circuit.

 

Also....try holding the window switch up or down, while you lock and unlock repeatedly to see if the window moved any while it locks and unlocks.

 

This is not easy to search through...I hate hunting for ground faults.

I had both my regulators n motors on my windows fixed because they both died and when I had the local place do it he was done in like 30-40 mins both sides, is it possible he messed something up ? Also on occasion when I have the door open and unlock it to see it makes a fast clicking sound as if a battery connection isnt fully connected, also both the driver side n driver side(passenger)window swtiches are not working at allbut the passenger side switch works fine.

Fault could also be in the switches.

 

Well is it safe to say that whatever they did when they redid the regulators/motors that they messed something internally in the door as they disconnected alot to take the door panel off

      2 speed transfer case optional now?

      By newdude · Posted

      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.

      Different requirements for oil filters?

      By newdude · Posted

      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. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      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.
