Heater blowing cold air

I have a 2006 PT Cruiser, and the heater is only blowing cold air. There is plenty of coolant in the car,and the temperature gauge never goes above half way. Any idea as what is causing this?

Feel the two heater hoses going from engine into the firewall. Both should be hot when the engine is at normal operating temperature-showing that the heater core is circulating coolant.
If both hoses are hot or warm at least, then your heater case doors are not operating properly. The temperature blend door that allows air to flow past the heater core and pick up heat is probably the culprit. Check on the case doors-they are probably vacuum operated. Watch for movement on the vacuum controllers as you work the controls. They're all different-figure out which are working and which one is not. Vacuum hoses go to little canisters. When vacuum is applied, the diaphragm in the canister pulls a lever inward on the canister's end. The canisters and levers are attached to the various doors, opening and closing them as demanded by the dash controls.
The vacuum for all this jerry-rigged stuff is a single vacuum hose from the engine, through the firewall, into the back of the HVAC control head, or heater controls, where a pod-like thing can distribute vacuum signals to several lines, often color coded, around the heater assembly case.

SOURCE: Overheating and heater not work

there is a valve on the water pump and one on the thermostat housing open those up one at a time until you get a little bit of antifreeze come out then tighten them back up. All you will be doing is bleeding the air out of the cooling system. my car was doing the same thing after I changed my thermostat.

SOURCE: My car heater is blowing cold air

The shut off valve on the heater core was left shut during the repair on your coolant system. the repairman forgot to re open the shut off valve . this is the problem. open the shut off valve and, the air will become hot again. as for the gauge fluctuations, the actual gauge may be malfunctioning.

SOURCE: heater blows cold air. also, the temperature gage

Even 160 degree water should blow fairly warm air from the heater. Feel the heater hoses to see if they are hot--if so, then a bypass valve in the heater air-duct system may be in the wrong position--look for loose or damaged vacuum hoses. Check the defroster ports for hot air. Check to see if the temperature gauge drop coincides with the radiator fan coming on. If not, the thermostat may not be working correctly. Also, 160 degrees seems a little cool for a modern engine (check the thermostat).

Why does my 2006 pt cruiser have no heat inside car?


Yes. Feel the hoses at the firewall with the engine at temp and make sure both are hot. If 1 is hot and the other cold most likely a core plugged.

Check your coolant level first and then check your radiator pressure cap. If not one of these it is likely a sensor/valve in the system controller and you will likely need to go to a reapir shop for help.

Heater blows cold air only 2006 Dodge Charger?


Check all vacuum lines first for any possible leaks especially if you have a flow control near firewall or hoses going through firewall. If you feel hoses going to heater core, are they both hot to touch when engine at normal running temperature? Coolant level is up, and been bled properly? Did you have to add coolant lately for any reason?

I recently had the same problem with my car. The solution for me was to remove the coolant lines going into the firewall(be sure to let it cool down first)and blow out the heater core with compressed air.I went from blowing barely luke warm air to awesome heat...good luck

2001 pt cruiser no heat


did you check the fluid level by removing the rad. cap? Radiator should be full to top. If Chryslers are low on coolant, the heater will not blow warm air.
