Have a 2017 Journey STX with a 4 cylinder. The heat blows cool and the passenger side and hot on the driver's side. I replaced the door inculcator for the recirculate which was clicking loud and the one for the heat on the passenger side. Still acting the same way. My next step was changing the two thermostats. Approximately a 40-degree temp difference until the engine coolant temp reaches about 150 degrees, then it will be warm on the passenger side and plenty hot on the driver's side. Any ideas?
