Rattle

Have a rattle coming from passenger side behind glove box during certain times, have had dealer check it out and can't find. I'm thinking computer board, has anyone else had this issue?

Lots of people has/had this Vibration problem with the computer vibrating. Stick some thin rubber foam behind it.

I had this as well.. ended up being a bracket that held some cooling pipes in place that was located to close to the firewall...all they did was bend it back away from it... there is a bulletin out for this PIT5505

ECM was my rattle as well. Take ECM out of bracket,put foam between ECM and bracket and re install. The diesel engine shakes at low rpm and the wiring harness to the ECM from Engine vibrates and causes ECM to vibrate in the holder creating a buzz/rattle. I could have swore it was coming from inside behind glove box. ECM is right on the other side of firewall from glove box in engine compartment.

I have a rattle somewhere on the ac/heat control panel. At least that is what I think!

If the rattle/buzz comes and goes with engine rpm , but NOT with bumps in rough roads then look into the ECM shake.
If it only happens during bumps or rough surface driving then not usually the ECM, but some plastic vibration, wich is usually worse when cold weather.

I think mine is from after I hit bumps it starts but keeps going some times. Drives me crazy. It is quite then hit some rough patches in hyw then a vibration rattling plastic noise starts and sometimes don't stop. Then may be gone after a while then start back up. I think ill ask my mechanic here at work to see if he can at least put rubber foam behind ECM to at least take it out of equation. The if it still does it guess ill see about the cooling pipes next. Someone mentioned glove box screws but I down know where they are and what they mean on that one.

Why is it that you pop up right away on small things like rattles and radio issues, but are nowhere to be found on the seriously problematic issues, like the shifting problems? By coming on here you are the face and representative of GM. Not just to an individual customer, but to all other customers and public with access to the internet. You're really reinforcing the growing perception/opinion that GM couldn't care less about their customers with this very real problem that has been PROVEN to be completely fixable. Multiple aftermarket tuners have been able to completely fix this issue. Why won't you?

Hi guys - I had a terrible metal on metal rattle in the passenger side dash of my 16 CC diesel. Took the glove box out, searched around - the two main screws that hold in the passenger airbag were able to be turned with my fingers. Took 6 or 7 full turns of the bolt to get them to snug down. Metal on metal rattle gone now, but holy cow - not reassuring that the airbag wasn't tightened down. Now I have a plastic on plastic rattle. I've narrowed it down to the little device with the string that keeps the glove box from dropping like a rock. It looks like a total pain to get that little thing out, so I haven't been able to remove it and test, but a tap on the black plastic bar around that thing causes the same noise when the truck hits a bump. Sounds like a spring rattling in a plastic tube.

Seems to me that the whole point is to get complaints off a public forum and have them sent to private messaging where they will not be seen.

I had a similar coming from the glove box area when ever I hit a rough patch of road. After trying to figure out where it was coming from for a couple of days, I finally found the source. It was actually the screws that run across the top of the glove box compartment. They are visible once you open the glove box. Two of them were completely loose and about to fall out. They screw into metal clips, so it was a metal on metal rattle. Easy fix. Something worth while to check out.

I think I heard this today. 600 miles on my truck. Will be listening more closely going forward. Have to turn off audio and HVAC and run low speed and I think that is the triggering scenario. Going to subscribe here to keep up with this.

My rattles are fixed now but one was the trim around the speaker in the middle of the dash and the other was the trim around the rear view mirror.

The mirror trim just need to be pushed on to be popped into place.

I'm working on tracking down my rattles. I'm fairly certain I have the dreaded door rattles but I thought I'd check all these as well.

Those 4 screws on the top of my glove box were completely loose as well. I'll have to drive around to see if that removed one of my rattles.

Good deal! Hope it resolved at least some of the rattles. I ended up using some loktite on them to prevent it from happening again. Those little suckers can make a lot of noise when loose!

Mine is the passengers side door, they looked at and said, "No abnormal sounds". 😳The other drivers side door doesn't do it, lol. I'll be tackling this one one day.
