In my 2010 Elantra I’m only getting heat on the driver side. It’s not the Blend Door actuator because the heat does switch vents correctly so that’s not stuck. I know there are other actuators but I’m not sure which one could be causing me to only have heat on my drivers side and not the passenger side, if anyone could tell me what the other actuators are and where I would find them in my car it would be much appreciated. Also we have flushed the heater core multiple times and replaced the thermostat (even replaced the controls for the heat). At this point we believe it has to be an actuator just not sure which one.
