Well my 2019 early build leaker was replaced with 2020 hopefully not leaker. No signs of an leaks on the window or headliner of the 2020 so fingers crossed. Very impressed with the 10 speed after th

No leaker here so can't do a 100% verification, but the problem seems to be with the spoiler design, regardless of weather the sealer leaks or not, and any cracks in the trim make it worse.

Do you do it yet? Washed the truck this morning and checked. No leak. 

So, it's been over a month since you installed this and no leaks? 

 

Must be leaking from the spoiler bolts and running to the top of the window from the inside.   Goin to order this and try it myself!! 

 

FYI- I ran a similar rubber seal between the window and window frame on the outside, across the entire left side of the window and it didn't stop the leak....so I think it is coming from the spoiler bolt!  

 

Washed my truck yesterday and it's still dripping inside on the driver's side, at the plastic piece on the top of the window, still just a few drips but dripping nonetheless! 

 

This picture was a few months ago, but that is the spot, right on the corner of it!

 Yep did it a couple months ago but the truck is parked in the garage, my wife and I are both working from home and it hasn’t rained much. Can’t guarantee it, but so far so good. Worst case you’re out $15.....

Update on the Trim Lok. Had a few days of rain here and no sign of leakage. I highly suggest you give it a shot. $15 and about 15 mins worth of time.

I ordered this exact Amazon Trim-Lok product, but I cannot get it to fit into the upper gap of the spoiler.  I even tried lubricating it with some silicone spray.  How did you guys do it?

I just put it in yesterday...I'll keep you posted.  I plan on water testing it instead of waiting for rain.  Full disclosure, I don't have a leak since they replaced my rear window.  This is more preventative.

I used interior plastic trim tools to get the cord between the spoiler and the cab.  Gap was that tight on my truck.

Anyone that's had the window leak fixed under warranty via a dealer, have you noticed an interior rattle after the work was done? Apologies if this has been brought up. Tried searching the posts but no luck.

Mine was repaired last week at a reputable dealer where I purchased the truck. Noticed this morning on my early coffee run with no music, etc a distinctive rattling on any little bump I hit that def wasn't there prior. I'm hoping it's my son's car seat and/or something he left in it, [emoji1787]

2019 LTZ 4x4, 6.2. For reference.

I used the handle end of a plastic frozen yogurt spoon to work it into the gap.

Might be the headrests on the backseat.  Do a search for it on the forum.

Same here, small drip, just about not noticeable but found it after a serious hard rain.

Headrest rattle like others said before, easy fix to just spread the headrest legs out

OR

Rear cab vent(s).  Check to see if they didn't knock those out.  I got mine back after the window and the driver side cab vent was loose. 

OR

Could possibly be spoiler attach bolts.  I personally feel that this might be a big part of the leaking problem, as my window wasn't cracked...but they insisted on replacing it anyway.

When they did, the leak was worse, and in a different area because they didn't seal the spoiler attach points.  What a mess.  Still have a noise in the cab during extreme temp changes...and I believe it is due to the spoiler not torqued correctly.  Which led to the leak.  Just my theory.  I am probably way off the mark.

Yes I had the rattle. Pulling the headrests and “widening” the bars did the trick. Hopefully I can just enjoy my truck now. No leaks since rear window replaced.

Wow that is considerably worse than mine. They discovered a foot of sealant was not applied at the factory. They ordered me a new window regardless.

Mine is getting worse too.  Doesn't even take much moisture anymore.... just a light rain and the interior is wet. 

 

They discovered a foot of sealant was not applied?  Is that new info?  Source?

      Would this be normal or a worn CV Shaft? 51K miles 3.5" lift? Boots are intact and no visible leaks showing. Attached is a the video I took. Thanks     https://youtu.be/ZnW7PPRmjJY?feature=shared

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      If everything checks out at the MAF, then the MAF is BAD, new or not.   You don't need a signal generator to troubleshoot this. PCM needs ALL powers and ALL grounds able to light a halogen headlight bulb - if it can light the bulb bright, then the wiring is good enough to run the PCM.   Best thing you can do for yourself is spend some time here: scannerdanner.com - Check out all his YouTube videos on similar issues. If you decide to subscribe it's the best bang-for-buck ratio in the automotive world, hands-down. He's got TONS of free vids on YouTube, too.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      Yes, I used my multimeter to probe all of the wires at the MAF, both with the sensor connected, sensor disconnected, key on engine off, key on engine running, etc etc etc. I probed all of the wires again at the PCM, at the connectors, etc. All voltages are what they should be according to the service manual/wiring diagrams. All grounds are good, less than 20 millivolts from the battery negative under load. Both at the connector of the MAF, at the PCM connector etc.      I know this throws a pretty big wrench into things, but this truck was acting up before the swap. I don't have very much information, if any on what was causing it, but if you cleared all of the dtcs it would do the same thing where it would crank, fire, then die. And it would do the same thing a dozen or so times, and eventually it would start and run, but the difference is that it would run and actually be drivable. Whereas now if you can drive it at all, it goes into reduced power mode almost immediately, and even then it's not running correctly. When you come to a stop at a light it stumbles down to for 500 RPM before catching itself and returning to the smooth idle. And if you go more than about 50% throttle then it immediately goes back to doing the misfire thing.    Like I said, I know that throws a wrench into things, and unfortunately I was not able to pull any data or anything like that before I did this work, so I don't have much to go on.    I'm trying to not fixate on one particular thing as the cause of the problem, but it seems like all avenues are pointing me towards the PCM. Like I said I have tested the wiring extensively (see above), and during cranking the sensor does produce seemingly legitimate values at least according to my multimeter, but as soon as the engine fires those values quickly descend into gibberish. I've tried it with multiple different known working sensors, I have done literally every test I can think of multiple times on the wiring (probing the signals, probing the pins with the sensors unplugged, probing the pins at the PCM, voltage drop, voltage drop under load, continuity, ohms, and double-checking everything against the wiring diagrams/ proper values in the service data.)    Another thing that pushes me towards a possible PCM failure is, I have noticed in troubleshooting a little bit taking a break and coming back, that when I leave the truck to sit for a while and cool off, it starts and runs smoothly when I first start it up. However once it warms up. It starts having problems. For example, when I went out to the truck this morning after it had been sitting overnight, I was actually able to drive it down the block. And then once I got on the throttle a Little bit after going about a thousand ft, it started misfiring again. I pulled it back into the driveway, shut it down, and started it back up. It idled smoothly. As soon as I touched the throttle it did the misfire thing again. From then on as soon as I started it it would misfire. I shut the truck off and went to go get a coffee and do a bit more research. When I came back out I started the truck up and it immediately went into the smooth idle. After a couple of minutes of playing around with it, it would not idle smoothly anymore. Let it sit a couple of hours, rinse and repeat. This makes me think with temperature change something is going wrong inside the PCM. I have the PCM out of the 2007 donor vehicle and I'm thinking of getting a one-day subscription to the ACDelco programming service to try and program that and see if it helps.   Like I said, I'm really trying to not fixate myself on one potential cause, but it seems everything is pointing me towards PCM failure. I would really like to try to confirm that, but unfortunately I don't have an oscilloscope or a signal generator to do the GM service procedure where you feed 5 khz into the signal pin.
