Just today noticed on heat with auto and sync on that the air out of all vents was warm on the passenger side however was not warm on the driver side. Full A/C works fine on both sides.

Any Ideas what this could be?

TIA

 

Changeover valve/solenoid?

 

^^^ Would be a likely candidate

 

Thanks for your input.

Hopefully the dealer can fix this easily without issue.

Of note: the same night the heater was working fine on both sides.

I'll let you know the outcome after I pay a visit to the dealership at my 20K mike service next month.
