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?

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
