Steering wheel rocker switches

[schweet787]

Hi all - 

2014 Edge SEL here.

 

A while back, the rocker switches on the right side of the wheel started acting up.  If you push volume up, nothing, if you push volume down, the volume goes up.  Same with seek - seek up backs up a track, down does nothing.  Same with the voice command button and the navigation on the heads up control goes wonky too.

 

Any idea on what might be causing this and if there is any "easy" fix to it?  Confident in my DIY abilities to a certain extent.

 

Thanks!

I'll take a guess as to what's going on. The switches are mechanical switches with embedded resistors. When you press a switch, it sends a current flow at a specific voltage to the ACU. When a switch fails, it's normally only one switch. As you have multiple switches failing, I think it's safe to assume it's probably not the switch unit. UNLESS.. there's a corrosion problem in the unit or at the connector.

As some signal is getting through, think we can assume the clock spring is functioning properly. That takes us to the either a failure in the APU or APIM (I'm not certain where the signal is processed in the 14.)

My initial guess is corrosion somewhere. I'd pull the switchpack and start looking for corrosion there. Then the clockspring unit.

I would not assume the clock spring is functioning normally.
