[@davidraezer5937]

That’s interesting that now the system is happy when the position is lower than the learned value. So what it didn’t like was exceeding the learned value. It’s a shame GM didn’t incorporate window learning by using the open close switch like most cars with pinch protection. At least they provide free play adjustment to compensate for cable stretch which seemed to be the root problem. Great video Ivan you have a lot of dedication and I’m glad you found your niche.

[@flycatchful]

Bingo, you have come to the correct conclusion.

[@bobspurloc]

actually its more of a logic flaw. why exactly would you stop the roof from working because the window opened/closed 1 click too far? what's that actual distance to cause it to be a no go. why did they code it to be over sensitive.

[@davidraezer5937]

@@bobspurloc definitely agree with your statement. To be more critical of the software coding is the high number is when the window is down. The low number of 26 is more of a critical number due to the overhead roof conflicts. I think if the sliding roof idea caught on and more people bought this option they would have probably revised the software. Studebaker was the inventor of the sliding roof for the Lark wagon called the Wagonaire. That was criticized for its tendency to leak and rust. GM took their idea and made it better🤣

[@russellhltn1396]

It looks to me like it will re-learn on it's own, but there's limits. Perhaps it only will work if it's only one count over. This thing was drifting all over the place.

[@PineHollowAutoDiagnostics]

Wow that is crazy haha

[@picklerix6162]

As somebody who has written firmware for actuator positioning, one way to control motor speed is to use PWM with voltage feedback. That way, the window motor moves the same speed whether the vehicle is running or not. Also, the motor speed can be slowed down as it reaches the set point to prevent overrunning the set points for open and close positions. Probably the easiest fix would be to implement a fudge factor which allows the roof to operate as long as the window position is within so many counts plus or minus of the open position.

[@paulstandaert5709]

It seems like 650 was a threshold where if it went beyond that, something was determined to be faulty and the system would no longer function. I suspect that someone was in there before, which is probably why the motor was not mounted securely, and in the whole process of dinking around, the motor would go beyond the counts that it should be able to. It would be nice to set a code for something like that.... like "end gate window motor position beyond limits."

What do you want to bet that was actually supposed to be part of the procedure, to loosen that white plastic stopper nut thing, do the learn, then reset the tension on it a bit higher. The only alternative is that the programming is inherently flawed and unable to compensate for wear over time. Can you imagine a car not starting because the IAC counts were one more than the predefined limit? Same concept, different system. Glad to see this rare little beast fixed, and the owners happy! There is no better feeling in the world than clutching a victory from something that's been beating you down for so long! :D

[@kellygibson7299]

What a crazy ride that was. I get it, the module wants to make sure nothing clashes so it was doing its job. The repeatability was key; if you cannot answer the “what” then finding the “why” is nearly impossible. All around, the customer, Keith, and yourself did an excellent job at proving the process and how doing any job is worth doing 💯

[@ecaparts]

Wow this one took Ivan AND Keith to fix!! The problem is not having the data to properly diagnose, too many variables and no DTCs. Hindsight is 20/20 and now it seems as if the windows open count limit is 650. Most likely the cables just stretched or mechanical stops moved causing the counts to go over 650. Why didn't any DTCs set? It wasn't happy because the IC displayed the message. Frustrating! Thanks for the amazing case study! Great job, Ivan...

[@Brian-cr6rb]

You are amazing! I'm glad I'm not the only one who has experience in fixing something without having a clear explanation of what was broken to begin with. Stuff like this throws off the experience of "I've seen this before " diagnosis. Thanks for the through walk thru of this wacky issue.

[@mtebaldi1]

Everyone in the comments below stated it all Ivan you are the best diagnostic Engineers on this planet. Great job to you and Kieth.

[@brainndamage]

I would lubricate all the window gaskets and sliding points with silicone spray. Maybe it has too much friction and the controller thinks the window is already at the end of position (stalled) and goes into a fault.

[@brainndamage]

Also it looks like those two white plastic parts on the cables adjust the end stop positions that the encoder sees. It seems like there should be a calibration procedure for their adjustment after replacing the window regulator. If there is none that seems like a big oversight from the manufacturer (and also a bad software design that is too sensitive to end stop position changes)

[@PineHollowAutoDiagnostics]

The fault is purely for encoder counts being too high. Apparently 650 is the magic limit lol!

[@_RiseAgainst]

I thought the same thing, but apparently the window was moving too far, not getting stuck.

[@philnotley5138]

Could be a bit of wear and tear in the actuator bit of stretch in the cable and being all loose and flopping about was the cause mechanical rather than electrical? Once you tightened it up and took a bit of slack out of the cable it seems to be ok well done fella

Adjustment for cable and gear wear. Similar to the mid-cable adjusting provisions on motorcycles. The grommet certainly didn't help, but it needs a washer. Great job to both of you for getting it fixed, but I have to say, sometimes we have tunnel vision for the trade we work in. Sparkies = Electrical. Me, Brakes.

[@mikechiodetti4482]

I think you found THE problem now. There could be some or a lot of wear even though that system is not used on a daily basis. Since there seems to be zero tolerance for the program the computer is doing it's job, except that is a real PITA! Any chance there's a TSB with a programmable update? That system needs to be told to ignore a few counts change every time the window goes up and down especially with the engine running. The alternator could have some "stray A/C" coming out of the diodes or the ignition system might also be affecting the system's program. Just random thoughts here. Good one Ivan.

[@Hybriddiag]

Your persistence is remarkable sir....congratulations on a repair infact over repair😂...cheers

[@flatdaddio]

Wow, not sure encoders are the best for that application. Some type of limit sensor/switch would be better. Encoder would be OK if there were different functions at different positions, but there's not. It's all the way up, or all the way down. The whole system is prone to failure with just normal wear with the tolerances so tight. Each count on the encoder must only be a few hundredths of an inch. They should have at least given it a landing zone between xxx and xxx ok for the roof to open. Way overkill in my opinion. Great job Iven! You have the patience of a saint!

[@volvo09]

Oh man, what a crazy journey! It would be nice if there was information on the full operation theory of the roof system, it probably would have helped you. The owner also takes good care of the truck, it's in good shape, i can see why they wanted to fix it.

[@xeroidkid]

Ivan, if I can throw my thoughts into the mix. What about checking the continuity between. The main car body and the tailgate. The small amounts of resistance between the 2 bodies could account for the loss of current, possibly intermittently throwing out the learning algorithm. It would account for no Diagnostic codes being displayed. Only a slotted opto disc arrangement would accurately measure window movement, plus the fact that motor actuator not being secure wouldn’t help either. Placement for the window is paramount because the roof need to meet accurately together without causing possible damage. Without human intervention. Good luck pal!

You might want to add a fender washer on top of that grommet to keep it from wanting to pull through again. Experience tells me if it happened once, it will happen again.

[@robertheim352]

My thought also, it would compress the grommet.

[@jayandmargie]

I agree that adding a washer is a good idea to make sure everything stays in place. However, it won’t have anything to do with keeping the problem from recurring. Remember, Ivan put everything back in place securely, but continued to have the fault due to overtravel. It wasn’t until the spring mechanism was readjusted to limit the travel, that the system stayed happy. As long as that setting is maintained, everything should remain good.🤞

[@HueToobBlows]

@@jayandmargie All fine and good. EXCEPT! Since that grommet is already stressed, the odds of it staying in place are slim at best regardless of travel. And since you can see that the grommet was a good distance away from the mounting hole, it means there is also stress in a perpendicular direction wanting to pull the grommet through the hole again. A washer would definitely prevent this. Especially after all the bullshit the poor customer has been through. Why take the chance?

[@wallace3953]

@@HueToobBlows great observation and sound recommendation....also, can they acquire an OEM washer/grommet? OK, tell them to acquire 2, and keep the extra in the glove compartment, in a clearly marked envelops. Cross fingers, and walk around the vehicle 9 times....praying to U know Hoo!!!!

[@jayandmargie]

@@HueToobBlows I don’t disagree with you that it would do a better job of securing the grommet, and the motor in place. I was just pointing out that the movement of the motor didn’t end up being the cause of the overtravel. The fix was adjusting the cable and spring at the motor. As long as that adjustment holds, and the integrity of the cable jacket remains, the problem shouldn’t return. If the cable jacket were to crack, and then compress more, it could result in overtravel again. I’m sure the motor, being properly secured, could help to minimize the chances of this happening down the road.

[@SHSPVR]

Here's my thought on this Ivan I think the plastic gear inside the motor is worn just enough to give it a few extra count because it takes more force to go up than it does to come down so when you move that spring into a new clock position you change the positioned you could have just filed a new slot just in front of the old slot to reposition it.

[@MrPitatom]

Hey Ivan. You and Keith are masters of your craft. Kudos to you both. I have a similar experience with my 2003 745Li BMW. I had to replace the front passenger side window regulator. I bought a non-genuine regulator and guess what, a similar thing happened. When I put it through its relearning phase, the window would go up and then down and the software report came back as a fail. I made so many adjustments but it was no good in the end, I just couldn't get it right. I bit the bullet and bought a guanine regulator ($600 Australian!!!) and it worked perfectly. I guess there are tight tolerances in these devices.

[@mykofreder1682]

Rear glass and roof have some safety, don't snap off the glass, interlock and it has hard coded limits for this interlock, defiantly looks like a programming glitch. If the window is up an inch or so it isn't that unsafe to open the tailgate, the rear window going up and down is why they have this check. If it were a fixed window in a door frame it would not have checks and also would not flip down. The connector fix is temporary, the opening and closing will dislodge another design flaw. Looked back at the operation of 60s wagon tailgates, some had interlocks but not to the last 1% or they had a window in a frame that went up.

Im proud to say i learn alot from you ivan thank you so much

[@fjr2go]

What a journey.... well done!

[@jameswest848]

Wow. Use end stop switches and be done with it. I admire your tenacity!

[@Keanu-x7w]

Owner wanted back to factory.

[@jameswest848]

@@Keanu-x7w Yeah, I wasn't clear. I meant at the design stage, not for Ivan to bodge. I wonder if my VW sunroof uses this encoding method, it gets possessed sometimes!

[@CarlWilliams-u3y]

If Ivan would get a Launch x431, he could activate switches and test modules etc. It's easier to use. Disconnect the battery first for a few minutes to erase module memory.

Kobayashi Maru for the win - changed the limits

[@greghanlon2235]

Glad you sorted it and admire your diligence. Seems like a majority of the ultimate fixes on this channel come down to what's spotted during a thorough visual inspection. If staring at scan tool for hours and multiple relearns don't answer questions, maybe old school looking for something f*cked up earlier might answer questions if done earlier? Ask yourself, what if the previous tech was a tweaker? lol.

I would lubricate all the weather stripping and the track , you can hear on video that the load on the motor fluctuates. After all friction points are over lubed and cycled a few times I wouldn’t be surprised if the relearn is needed again.

omggg! You solved it.....but....from encountering moon roof issues on a lexus rx330, 2004, Suggested First Steps: 1. Open the window, roof, door, whatever . Get some Cleaner wax...can be liquid. Apply the wax ONLY to a towel applicator. Carefully cleaner wax all contact points ON THE VEHICLE BODY BUT NOT NOT NOT on the rubber seals. got that ?? Carefully remove the wax. Do it 2 more times. Make sure to remove all the applied wax. Now U have a clean, somewhat correct surface. NEXT, Silicone Spray the rubber/seals/whatever. Let the spray dry. wipe off the areas. NOW, basically, it should be factory ready. Next, work the window, roof, etc whatever, open and closed....Does it need more silicone spray? Next, spray silicone spray into the seals....They are dry, usually. Let this dry. Then, operate the LEARNING CYCLE, if so equipped. FROM YOUR VIDEO, IT IS IMPORTANT TO SEE IF ANY ASPECTS ARE MECHANICALLY LOSE, OR HAVE BEEN KNOCKED OUT OF ALIGNMENT. Then, after all this.....do your intricate analysis....Always operate the windows, roof, etc, under a "System Charging" Voltage. To do less is asking for the spiteful spirits to appear....hear them laughing??????? U r the BEST!

I know nothing about modern station wagons , When I was a child our 56 Ford wagon was all manual , never had that problem looking out the back window in our reversed seats , lol.

[@PineHollowAutoDiagnostics]

It was like a 10 round boxing match 🤣

[@dougkubash8673]
