I have a 98 Dodge Stratus with a 2.4. I have replaced many things Water Pump and many other things. I have no heat in my car at all but it does blow but only cold air 100% of the time. I changed the radiator and thermostat just recently and no help. It is not the heater core because it doesn't leak or smell sweet in the car. Since I live in Michigan it gets cold so any ideas would be helpful.

 

hows the antifreeze level?could be a clogged heater core or cooling system, blend door(motor or cable to door) could be bad,switch bad not sure if yours is mechanical or electrical, there is a technical service bulletin out i'm not 100% sure(don't have my stratus any more, gave everything i printed out over the years to new owner) if it applies to your car it covers certain 1998 thru 2005's models. basically you remove the M-1 fuse( not sure which fuse it would be on 98's) or unhook battery for 10 minutes, rehook battery let idle for 5 minutes, check to see if you have heat then.

 

Found out that it is a clogged Heater Core.

 

Well what doesnt make since is that make since are that both lines that go to the heater core are hot and from what I learned is that one would be cold to the touch if the heater core was clogged.

 

Well, if you peak inside the heater core, you will probably see a coating of Calcium or Amonia build up. These build up will reduce the heat transfer rate between Coolant and air. It fails just like how your water heater fails overtime. You got gas and fire, but the water isn't getting hot.


You can just flush it out with some chemicals cleaners.
