2007 Yukon Denali Speaker Issue
On my 2007 Yukon Denali the driver's side speaker sporadically goes in and out when I am turning left or
when I go over a bump. It's very sporadic and doesn't do it every time. Also, it seems that when it does go
out and I stick my hand between the seat and the console and "jiggle" it a little it seems to come back on. I
am not aware of speaker wiring being under the driver's seat but this seems to correct it for some
As you can assume, this is very annoying with it going in and out when going over bumps and turning left.
Any help for solutions would be greatly appreciated.
It does indeed sound like a wiring issue. I'm not familar with the Yukon, but you'll have to move and remove some parts to get to those wires your jiggling around and see where the insulation is off or the wire is compromised/bent. Have the radio on and car off while you move the wiring around to see which one is the culprit. Having a wiring diagram specific to your vehicle might help too.
I would guess that when you wiggle your hand between the seat and the console, the front end of that console is wiggling something under the radio. You might have a loose connection up there.
