I have a problum with my heater in my 1999 Plymouth Breeze. It has a 2.4 dohc engine also automatic trans. I flushed out the cooling system, replaced the thermostat, also checked for any leaks in the vaccum lines. The coolent temp is good does not over heat. I also can hear the vent change to the heat still no warm air, just blowing cold air. :Shock:

Try warming the Vehicle, then carefully feel the heater hoses, are they both hot? If one is cooler than the other, You need to flush the core, or a replacement job on the heater core. Also if the system has a heat control valve on the heater hose, make sure it is working!

Thanks. I have one hose heating up and one not as warm. To replace the heater core is it very hard to remove the old and in with the new? It looks as if I have to take apart the left front of the dash board to get to the core.

Thanks again!

My advice is to have a radiator shop blow it out. This will clear out the crap in the core, yes taking apart the dash, removing the heater and a/c cores, and recharging and refilling are a bit of work, Think your up to it?

Is it very hard to remove the ac core? Also do you need any special tools to remove the ac core? I am up to the challange. I took apart the the cover below the foot area in the passanger side of the dash, I see the ac core cover and the blower motor. I haven't got that far yet, if you need a special tool to take the ac core out I think I will take it in to a radiator shop. Thanks for the help.

Yes you need the right size decoupling tool, but the set is pretty cheap! There will be 3-4 bolts holding the entire plenum from bothe sides of the firewall, thats 6-8 total. Cap the heater core ends, so you don't spill that crap al over the inside of your car.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
