Question about 2004 Chrysler Town & Country

Heater not blowing warm air

We recently replaced a water pump on the 2004 Town and Country; now when we turn the heater on, all we get is cool or cold air. We live in Florida, so don't use the heater much. Is this problem related to the water pump replacement?

After changing a water pump or radiator or heater core fill the system back up w/ 50/50 solution. Then start your engine and let it get to operating temperature while having the defrost on with fan on hi. As you add anti-freeze do it slowly and do not overfill so that trapped air can slowly bubble out. As the temp rises see if your defrost air is getting hot if so job well done. Top off anti-freeze and replace cap before shutting everything off. Good luck

Yes it is. when you replaced the water pump you most likely got a vapor lock in the system. meanig you got air caught in the lines and the best way to get it out is relaese top water pump line and fill with antifreez and then replace line to the water pump. and see what happens. hope this works for you. let me know.

I changed thermostat, radiator, water pump, hose, engine cooling temperature sensor, radiator cap and I'm still overheating. 2004 Chrysler town and country


Check the heater cores. There are usually 2 in a T&C. Also check the pipes running to the rear heater core. I recently had to have mine repaired because they were leaking!

Long time before heater blows warm air


That seems pretty normal, the heater works by blowing excess heat from the engine coolant. So the coolant has to be warmed completely for the heat to work, you can get a heater that plugs into your cigarette lighter that will heat the vehicle instantly.

My wife's 2004 Chrystler Town and Country is having an issue getting the heat to work (just blowing cold air), and now the engine has a tendency to overheat (past the midpoint on the gauge). Any...


I'm not a mechanic, but that sounds like a heater core might be faulty. I'm not sure if that could be clogged and prevent the fluid from circulating for cooling or not. This is just an idea from a non mechanic, who has replaced one heater core on a different vehicle years ago.

Heater blows cold air then hot air then cold air. but mostly cold air


Check your coolant level. Especially after you drive it and it starts to cool down. You have air in the system and it needs to be purged. Sad to say but chrysler/ dodge are bad for this problem. Some times you have to remove the hose from the heater core spout to get it purge correctly. You have to do this while it is running.

No heat air is blowing cold


First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced.
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is worm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest to flush the heater core.

CHRYSLER TOWN & COUNTRY 2003 HEATER PROBLEM


Have you checked the coolant level? If it's low, it will result in diminished heat, and could be the problem.
