So, the other day, the second and third preset buttons stopped working...sort of. They wouldn't work as preset buttons, but they did work when it came to the menu, or navigating when playing a cd. Once back to radio, they didn't work. Later in the same day they were back to normal. Today, the same two button stopped working, this time for all functions, as well as my menu button. Has anyone else experienced this?

 

OMG. IT WORKED.

I have a 2010 HHR-SS. While the buttons on the steering wheel continued to work fine, on the radio itself from left to right the buttons for "fav," presets 1 & 6, and "Eq" stopped working 2 nights ago. They came back to life briefly, but then were gone the next night. I just rapped on the volume knob as instructed and the affected keys started working again. I hope the fix lasts.

OK, a quick fix to try, and even though it sounds dumb...it brings the preset buttons back to life on both my 2006 and 2011 HHR's when the buttons go goofy every 18 months or so.

With the key turned to accessory, turn the radio off, and give the volume knob two or three sharp raps on its top edge with your knuckle, like you're trying to crack the shell on a hardboiled egg.

Then turn the radio on and check the presets for a return to normal function.

Why the head units lose certain functions on their faceplate buttons is debatable, but my technique of rapping on the volume knob has never failed.

 

How many dead threads do you need to resurrect with the same advice?

 

It could be that Auto fancy thingy that caused havoc if it isn’t turned off,

 

I read several remedies here that involved rapping or whacking it I tried the volume and that didn't work so I just gave the presets in the dial a good rap with the back of my fist a couple times & the 2nd & 3rdb button started working again so there's probably corroded connections is my experience that just aren't making up anymore.

 

The face plate comes off.
