can anyone tell me why or how to check my heater control .i only have heat on the left side vents front and rear. i have duel controls . i think it might be a mode door actuator but don't know were it is located. thanks in advance for any suggestions or help. it is a 2010 dodge journey 2wd 3.5 engine.

 

I have never experienced this but if you use "SEARCH" function
at the very top of this page and enter "no heat one side Journey"
it will give you relevant results that have posted on this forum.
