Hi all, just had a call from my mother whose heat has stopped working in her car. She said that it is still blowing plenty of air but it's ice cold and it just started happening today.
She told me that there is a funny smell coming from the car so my first thought is heater core, but she said it is not sweet smelling and there are no leaks inside or outside the car.
Any ideas?

blend door in the HVAC box could be stuck or broken,
or its cable might not be moving the door
the cable could have come off the heater control unit in the dash
later is most likely
pull the control unit and look to see if the cable is still on the lever and moving the cable
if there is not resistance to the lever or the cable then it probably came off at the door shaft in the box assembly
today i am working on a 99 breeze it has no heat at all from the heater the hoses are warm to and from the core, the lower rad hose was cold, the upper was as hot as the engine, i put a new thermostat in it and the lower got warm but not hot, still no heat inside the car at all,
so we are going to go ahead and pull the core out and replace it
has to be plugged up
doesnt make sense that both hoses are arm,
but many things dont make sense in this life
the old original chrysler 70k miles old thermostat was worn badly however,
very easy replacement, the easiest one i have ever replaced, no gasket, no sealer, no anything, its awesome :D
2.4L engine that is
replacing the core isnt that bad really, you do have to unbolt the entire dash and remove the shift knob and console, but its just a matter of some screws and bolts
not that bad, straightforward
remove the radio and HVAc controls bezel, and the dash end cap covers, they all pop on, just pry them off carefully, no screws on them
pull the shift knob and console
remove the underdash panels, round clips to pry out
unbolt dash, lift up and away some to get to the core cover
pull the core
now the opposite order
will tackle that tomorrow
