I had the same issue as everyone else - no heat on the left side of the car: replaced heater core, actuator, blend doors (all), thermostat, flushed 3 times, multiple shops and dealership could not resolve. THERE IS A CURRENT ATTEMPT TO START A CLASS ACTIONS LAW SUIT AGAINST FIAT CHRYLER BUT MORE PEOPLE TO FILL OUT A FORM TO GET IT GOING! Lawsuit Investigation: Jeep, Dodge Heating & AC Problems: https://www.classaction.org/jeep-wrangler-air-conditioning-heater-lawsuits "Attorneys have reason to suspect that Fiat Chrysler failed to properly flush the casting sand out of the engine blocks on some of its cars when they were made. It is believed that, as a result, the residual sand can circulate throughout the cooling system and settle as a “sludge-like” residue in the heater core, radiator and oil cooler. This is what may be causing the heating and cooling systems to malfunction and fail. "

Every winter my dodge avenger's heater stops working. I've had the heater core replaced,the thermostat. The blend doors flushed the system. It started working last winter. Now again it started blowing cold on the passenger side and now no heat at all. I've spent so much money on this
