I have a 2019 Sierre CCSB SLT X31 6.2. Whenever I use the 1 click/auto down function to control the front passenger window and then try to close the window by using the 1 click/auto up function, the window begins to rise, then stops about 1/4 of way up, then lowers itself again. Anyone else having this issue or know what could cause it?

Have you tried the window programming routine?

 

Programming the Power Windows

 

Programming may be necessary if the vehicle battery has been disconnected or discharged. If the
window is unable to express-up, program each express-close window:

 

1. Close all doors.

 

2. Turn the ignition on or to ACC/ ACCESSORY.

 

3. Partially open the window to be programmed.

Then close it and continue to pull the switch briefly after the window has fully closed.

 

4. Open the window and continue to press the switch briefly after the window has fully opened.

Thanks for enlightening me and providing those instructions. I had never heard of that before. It would never occur to me that system would require programming. Seems like the window needs to travel a certain distance or it could use limit switches at the top and bottom of travel, but I'm not an engineer. 

 

I followed the instructions, and it worked correctly a few times then it stop about an inch from being closed, then it went back to the original problem. I'll try again today.

If it's changed again that quickly on it's own it may be binding or have some other problem.

 

Time to make an appointment so it can be diagnosed.

I've owned a Canyon, two Silverados, and a Volt and every single one has had this problem. Is this a common GM thing? Every single one needed the actuator repaired under warranty

I've had about 15 or so GM vehicles (usually 2 here at a time, sometimes there have been 3 or 4) and I've never had to replace an actuator.  A good percentage of them ending up being high mileage vehicles, well out of warranty.

 

I think I've had to 'reprogram' the window in one of the trucks -- after trying to operate it when it was frozen in place due to freezing rain. 

 

I'd say that it's not common at all.

YMMV

I've had this issue off and on with my 2019 RST. I've mainly just found that the auto-up is very touchy to ANY disturbance in the window seal. 

 

Never tried the re-set thing mentioned above. Mine really only does this every once in a while. I usually clear my window seal/edge of any dirt or debris, then it works normally again.

I wonder if some of the truck/windows have glass that is mounted to the mechanism slightly out of place resulting in an increased chance of the glass binding in the track.

My 2019 Trail Boss also had this issue. The drivers window would roll half way up and then back down when using the auto up. It was very random as to when it did it. I tried reprogramming it, but with no success. I also didn't think it was old enough to accrue that much debris and dirt in the window tract. I took it to the dealer and they said they could not replicate it. On my drive home I tried it and it happened 80% of the time so I drove right back. They ended up investigating more and eventually replacing the regulator unit. I would suggest trying for a replacement before the warranty is up, because mine only seemed to get worse. Since the repair it hasn't happened a single time. I can take a picture of my paperwork if that helps anybody.

Mine still does it after resetting, but only about half the time. 

Then it probably has something loose or broken inside the door.

WAIT!  The passenger side has auto up?  I was pretty annoyed that my 2020 RST only works on the drivers side.  Auto DOWN on them both but UP only has ever worked on the drivers side.

OP has a GMC SLT trim.

No auto up on passenger side for the RST.  I think LTZ and up trim has the auto up passenger.

    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
