Check coolant level in rad on cold engine. If low you gort a leak. If level ok, replace thermostat and gasket
its a neon enough said. get a civic it will run forever.
For a 2009 Ram, Yes.Try experimenting with the AC/Heat Controls. I have noticed when defrost is on there is a miss in the acceleration, but when the floor heat is on, the acceleration is okay. I am taking mine in to see what they say about this. My 2000 Dakota had a miss in the acceleration but the dealerships could never find the problem (or did not care).1973 Dodge Coronet (318 Auto); 1993 Dodge Dakota Sport (3.9 Standard); 2000 Dodge Dakota Sport (3.9 Standard); 2009 Dodge Ram (4.9 Auto)...Things have been going downhill ever since I brought the 2000 model, and am not happy with the 2009. Needless to say, this is my last Dodge.
Blend door actuator.
it might have a sticking thermostat.
check your thermostat. or maybe your radiator is plugged up.
A possible cause could be that you have a clogged heater core.
check coolant level
It might, but not guaranteed. If there is a cabin air filter to begin with, and the old filter is very dirty, a new one will likely allow better airflow.
Sorry bad news Your heater core has a leak
The coolant is low, probably from a leak. You need to have it checked with a pressure testor.
Yes, replacing the heater core should slove the problem.
Its your Heater core if it smells like a syrupy sweet smell if not then its your thermostat
