Yes factory wiring is already in place. I would only need to add this 2 parts and I'll be set

Nevermind wires are only on the rear to connect the motor but non at the overhead console nor at the fuse box. Let me figure this out and I'll post what ever I come up with. I could always just use a

So when I was dealing with the Chief Engineer over the entire truck line with GM I posed this very question. He did some research with the other engineers and this was the info I was given. If your truck is a LTZ or SLT then the body harness has the locations for the switch for the window motor and the overhead console. If your truck is a lower trim than the ones I just mentioned the harness will be missing and it will not be possible to add the sliding rear window in like a factory setup.

 

GM offered to do my truck, cost was going to be around $3k plus labor which GM offered to cover, their only worry was if the dealer would be able to handle the swap and make it look and work like OEM. GM didn't want to take the chance on it and neither did I.

Sliding rear windows has been a popular option for decades. Just opening your front and rear windows a little will quickly balance the temperature throughout the cab. If running wires through the headliner is problematic, then run it under the floor covering. A stock style switch placement is not necessarily the best! I've had people wave back at me while I've been operating my rear window!

Yeah thats alot of money. I already got it installed during the weekend. I figured I'll just need to add 1 fuse, 2 relays one to open and one to close it will work as good as factory. So far I have spent about 275 on parts and a used oem rear glass. It shouldn't be more than 350 total when done.

Exactly what I posted earlier. Less than $500 to do it. Not $3k.

Yeah thats $3k plus labor. With all the tools, diagrams and parts available and they are not so sure of being capable to get it done right. Thats funny

Does the window go down (like in the doors) or does it slide to the side (like fords)?

The rear window slides to the side. A window that went down would introduce a few new installation challenges!

Did your solid glass break when it was removed?

      AFM Experience

      By KARNUT · Posted

      The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda.

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.
