HVAC Controls Dead

[Daskuppler]

Hello Everyone,

 

I have a 2014 Forester 2.5i without climate control.  This morning the HVAC controls were dead when the car started.  It was cold, but only in the high teens this morning.  After driving for a little while, everything came back on.  The entire cluster was dead.  Any ideas?  Fuses all look good, all connectors at the back of the cluster were tight.  A head unit was installed a couple months ago, no other work performed.  Parking brake safety switch wire was wired direct to ground.  I'm at a loss and have been unable to replicate the issue.  Google research points towards a control module, but I think they are only installed if climate control is on the vehicle.

 

Thanks
