I don't want my rear defog to come on during remote start. I've gone into settings, vehicle, remote start, auto rear defog "off" but it still automatically comes on when the outside temp is below a certain number. Anyone else have this issue?

I plan on disconnecting my wires to the rear defroster. I’ll never use it in Texas and I don’t want my window to blow out as I use remote start all the time

There are several examples of exploding rear windows found on the internet.  I am confident that the number of broken rear windows caused by rear-window defrost failure is miniscule next to the number of vehicles with this feature.  If there is an identified risk inherent with '14-'18 GM 1500's then why not check for a fix rather than disable this option?

I have the Silverado LT package and do not have the "rear window defrost" option on/off under remote start (at least I don't see it) but do have it under "climate and air quality". With your package level, you may have it in both areas and thus need to disable it there also.

 

In my case, the defrost activates at a certain temperature. If I'm on the road and that  temp is reached, the defrost feature should come on. Also, I would guess if the vehicle is remote started after a cold night, the temp again has been reached and bingo, the defrost switches on. Therefore, again in my case, I would need to disable the defrost feature through the climate/air quality section of the vehicle settings.

 

Just a thought.

I have the same problem with mine, its frustrating, I don't want the rear defroster on every time the temp is below a certain temp... I also cant get my heated seats to come on automatically either even though I have the setting switched to "on" ...

Thanks for that. I checked and you're right, it's under Climate and Air Quality and that's where I have it turned off. There's no option for it under Remote Start. Could have sworn it was though....

I just don't want my rear window shattering. My heated seats seem to randomly heat with remote start but I think maybe they turn on to "Low" which isn't very noticeable.

Climate and Air Quality
Select and the following may
display:
. Auto Fan Speed
. Auto Rear Defog
Auto Fan Speed
This feature will set the auto fan
speed.
Select Low, Medium, or High.
Auto Rear Defog
This feature will automatically turn
on the rear defogger when it is cold
outside.
Select Off or On.
 

Just know, there are no settings to disable the rear window defroster with remote start, it will come on and stay on until the manually disable it.

I'm in Texas... In the past 10 years I can't think of a single time with my old truck where I thought I sure wish I had a rear defroster. 

I'll never use it, so I don't care if its plugged in at all. and I really don't want my glass shattering for a feature I don't even need.

I just hope it doesn't throw some kind of error light when I disconnect it.

      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.
