Hi there - I have a 2012 Dodge Journey with heat/AC issues (I have dual climate control). We noticed it at the start of last winter, where the driver's side would have warm air blowing, and the passenger's side would be ice cold. We replaced the passenger size blend door actuator first, which didn't seem to solve anything. We took it in to have the heater core flushed 3 times (in the span of 3 months), which would fix the issue for about a week before returning to cold air. The lines were gunked up again every time we brought it in to have it flushed. Finally, we replaced the heater core in January/February and it got us through the remainder of winter with semi-hot heat.
Now that we are getting into cooler temps again, I put the heater on this morning and found out the cold air issue is back. Any further suggestions as to what we could do here??
