I just changed the cabin air filter in my 2016 Suburban.  Before the filter change, there was the normal noise when the A/C system was on.  Now, there is a HORRIBLE humming sound coming from the vehicle.  It is so loud, that you can hear it outside of the vehicle.  I popped the hood and you can hear it near the passenger side firewall, sounds like a sucking sound.  I read on here where debris can fall into the system when you change the filter, so I checked that.  Nothing.  The noise began instantly after changing the cabin air filter.  What have I done to my Suburban?  It makes it miserable to drive now.

You dropped an acorn or some other crap into the blower motor. You can't believe how often this happens.

I tried my best to check that, even shoved a ShopVac hose down the opening and no luck, still noisy as ever.

Okay.  I'll try that in the morning.  At work right now.  Thank you!

Ok, gave it a shot again this morning.  Removed the filter and turned the system on, hum is even louder with the filter removed.  Filter reinserted and the noise is still present.  Tried everything I could try to remove any debris that may have fallen in there and nothing comes out and cannot see anything in there.  Noise is driving me insane.  I actually want to set this thing on fire now.  J/K of course, but almost to that point.

UGH. I took it to the dealership the other day and they claim to have vacuumed it out and the noise is still present.  How do I fix this?  Please help me before I go insane.

I had the exact same problem.  Does the sound change when you use different doors?  Floor, defrost etc?  Did you use a Fram filter?  I did, same problem your'e having.  I pulled the filter 6 times, no kidding.  The final time I made sure all air and blower was off and the air flow on the filter was correct.  When I put it back in I went through all the doors with the blower on low and it quit.  I don't know why.  It quit though.  Sorry about the problem.

Hi Ghettosled, I’m literally in the same boat. 2016 suburban changed the air filter, which had a mouse nest, and now I have the worst sound coming from what seems like the compressor. Did you find a solution?

      AWD conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      OCI, not when but why?

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
