2016 Sierra All-Terrain Crew Cab with 6000 miles on the clock. The rear windows on both sides are not working from either the driver's or passenger's window controls. Driver and passenger side front windows work both from the driver and passenger controls. I've tried with and without the window lockout switch on, that isn't the issue. The dealer didn't have enough time to look at it extensively the other day, but they said it wasn't a fuse. Any of you have this happen and if so, what was the cure?

try the opposite of this, To prevent passengers from opening a rear door (if equipped) from the inside or open- ing a rear window, press the Rear Door Security Lock/Rear Window Lockout button located on the driver’s door. The button indicator will illuminate.

My ten year old truck had issues on the drivers side controls - the controls on the rear doors worked fine. The problem I found was dirty contacts on the switches in the drivers door console. I am not sure if they still have the same design between 07 and 16 but they are not the best design.

I second checking the contact points on the switches. Seems odd that both would stop at the same time, but I've had that happen before. Super easy and quick fix if that's the case.

Thanks again, for being a valued customer!

 

Regards,

I recently noticed that the rear door ajar indicator does not display on the DIC/speedometer gauge or give an audible warning. Rear windows are still inoperable. Being new to GM products (had Toyota pickups the last 23 years) are those warnings displayed for the rear doors? The front doors do give those warnings. Not too happy that we are already chasing electrical issues after 6000 miles.

Sitting at the dealership waiting to replace both rear window switches. Very bizarre that both switches went out at the same time. I will provide an update after the fix is complete.

*Update*

Dealer discovered a water leak coming from the XM antenna which had found its way down into the electronics/wiring. Dealer says they've replaced "several" of those antennas and their seals. They actually kept my pickup overnight because there was so much moisture in the door and under the carpet. Anyone else experience this issue? Should I be concerned with mildew or mold issues going forward?

This is a fairly documented issue on this forum, as far as water leaking through the XM Antenna. There is a small "slot"for lack of a better word, in the back of the antenna that is perfect for letting water in. Luckily I read about it before I bought my truck, and shortly after my dad bought his so I caulked them both before their first washes.

Makes me glad I only have 2 doors, good luck!

Glad you got that issue worked out. I wonder if the dealer would perform this repair to a truck that has not yet leaked? Kinda thinking of letting them fix mine before I get a bucket of water inside.

Also...what is the dealer fix? Do they just caulk the antenna?

Thanks guys. The dealer won't fix an issue that might pop up. Just keep an eye on it. I have weather tech floor mats so I might have noticed the moisture earlier if I'd checked under those. However, its the snow and rainy season here so floor mats tend to stay wet anyway. The dealer said there haven't been any reported leaks on the ones they've repaired. Just a bad design on GM's end. Not sure why GM hasn't changed the design yet?

I have an 09 LTZ Avalanche, both rear windows will not operate. I cleaned the contacts, checked all fuses, child lock, replaced the main control and still no resolution. 

 

I hear no noise, only the front windows will roll up and down, all the lights on the control work.  What else can I check? any ideas would be greatly appreciated.

      Oil pump noise was discussed before.  I will try to remember to record a remote start later this morning.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65

      Factory front brake rotors...defect?

      By Chris80s · Posted

      On my wife's 2020 Blazer (~69000 miles), we started to notice the brakes pulsating at faster speeds. Typically around town you don't notice anything, but highway/interstate driving you will notice it. I decided to pull of the front tires and look at the brakes. I figured with the milage, the pads should be wearing out to their life span, but they actually looked decent. Still with "meat" on them. One pad has a ridge wearing in it, and that same rotor is showing the ridge too. That's not the concerning part...the other rotor appears to have a raised bump on it!  The picture make it look like a pimple! Very odd and strange! NOTE: These are the factory brakes and rotors.   I'm attaching pictures of the front brakes and what they look like ate ~69000 miles.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      2024 Chevrolet 2500 HD Custom 6.6 Gas Canadian built Truck  I tried to search for my previous thread on this topic but cant find it so my apoligies  for starting another one    #1   Since we have owned our truck purchased new it has this strange noise after using the remote start function  you press the remote start and you hear it start but right at the end of it starting it almost seems like it wants to start again after the truck is running .   There is no gap in time it is right at the end of the start . Almost sounds like when you have started a car/truck and its running and then you try and start it again and you get that grinding noise ,sort of     #2  You can only hear this if you are standing outside of the truck and near the truck  you cant hear it when you start the truck from inside  the cab . So it may very well be happening when starting the truck that way as in normally    #3   This only happens when it is started after sitting . For how long I don't know but it happens after sitting overnight for sure and it wont do it if you stop the engine after starting and then start it again  I have had it in to the Dealership before concerning this but they did not have the truck  when it was cold to hear it . Now its back in the Dealership left it overnight so they could possibly hear the problem . They said they tried and nothing happened . Well they did not know what they were listening for . I started the truck remotely and BINGO it makes the noise . Oh that sounds weird they say . We need to look into it ! I have left for this week at the Dealership    Does your 2024 2500 HD gas do this ?  Any of you fellas care to take the time and trouble to film this operation from a cold start  so I can hear what your sound like  Really  would like to know if this is anormal sound  Thank You Fellas !!

      2026 Z71 Forward and Rear Park Assist help

      By Slow · Posted

      2026 Z71.  The other day I was backing a trailer into the barn.  The alarm was going off just because the trailer was in the field of the warning sensors when you get too close to something.  For some reason now the warning alarm doesn't work anymore.  It used to go off when I was just normally backing my truck into garage.  I still have the guidelines in the back up camera.  Is there a button or something to push to turn the sound/Alarm on and off?  I have the touch screen in this truck.  There isn't a "P" on the dash except for the parking brake.  I can't find anything in the touch screen under settings or vehicle.  Thank you in advance.
