Yesterday I got in the truck to go somewhere and noticed that my volume down button on the wheel was not clicking and felt kind of mushy. It worked one time to turn the audio down, and then I noticed that it was floppy and not returning. It's actually stuck pressed - so you can't use any of the steering wheel audio controls (if you use the faceplate controls they override the wheel until the next time you touch anything on the wheel and then they become authoritative). If I hit a bump in the road it activates and turns the volume down all the way as well. It's not physically stuck in there as you can make it jiggle - but the micro switch behind it is stuck.

 

I am supposed to drop it off tonight. I believe this makes day 27 of various warranty repairs.

 

Have any of you experienced this?

Just happened to do a search for this before posting and, yes, same problem on my 2020 AT4.  Time to call the dealer....

I just had the same problem happen on my 2020 LT Trail Boss, although nothing is quite malfunctioning, but the volume up button now takes about 5% of the pressure to push the button compared to the volume down. If my fingers brush over it while I'm driving the volume goes up. I now find myself having to lower the volume after every corner in the road. I'll be taking this into the dealership to get it fixed.

My 2019 just did the exact same thing. Volume up button quit clicking but still worked at first..... now nothing and I have lost all steering wheel control except cruise control. Another trip to the dealership, hopefully a quick / easy fix.

Anyone care to share what the fix has been?

I had this happen to the Wife's 2019 Blazer, required switch replacement, P/N 13540148, was replaced by the dealer, but took forever to get done due to technician availability.

 

Hope this helps.

Did warranty cover it?

Update? Also I’m in an even shallower boat, as my volume control on my dash also went out.

This just happened to my 2019. I was looking at videos of people taking apart their steering wheel but nothing that shows this repair specifically. I always fix everything myself but I may have to take this in to the dealer and my truck is no longer under warranty.

 

 

Chirping/ front drivers side in 2WD still there….

Buzzing sound when changing gears in cold weather still there….

same problem today.  I took the switch out and looks like part number is 13528615

this is off of a 2020 GMC sierra AT4 with all the goodies, tech pkg etc... 

 

the bottom of the steering column has a single 7mm bolt coming up from the bottom, and two facing the driver, you have to turn the wheel to expose the side bolts and remove bottom of steering wheel column, with a few locking tabs.

 

Remove two little panels, one on each side of the front part of steering wheel away from driver.  This exposes 2 bolts torx T-20 on each side (total 4) that go through the actual switch housing, remove those.

 

Remove 4 torx T-15 bolts from the steering wheel front cover(away from driver).

 

this should allow the steering wheel cover to move enough to get the switch out.  you have to disconnect the wire connector first, that's the hardest part, tiny little connector, the clear part slides out, away from switch, then push down on top of connecter while pulling apart.

I called the dealer to get a new switch and the part number has been changed/updated to 13540148 as stated in a previous post.

    • Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...      
    • The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge
    • Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).
    • The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.                 
    • It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
