1999 dodge caravan heater blows cold air?
First thing to check is open hood and feel heater hoses going into heater core located on r/s of vehilcle if sitting in driver seat.If they are both very hot and feel the same temp,blend door in heater box is not operating correctly.If one heater hose is hot and the other is cooler than chances are the heater core is plugged.In either case a professional would be your best bet for repair.Hope info was helpful.
What is wrong with your heater 97 Ford Taurus GL new thermostat new overflow tank no leaks never overheats Heater blows hot air for about a minute then turns luke warm to cold?
heater core plugged under dashAnswer If flushing the heater core doesn't solve the problem, the next step is to check the operation of the blend door. This model has problems with the door breaking and failing to control air flow through the heater core, appearing like the core is bad. Check heatertreater.net for pictures, diagnostic information, and a fix.

Why does heater defrost vent not open on a 1989 Sunbird and cold air blow from dash vents but no air blows from heater defrost vents and where are the enter and exit hoses for the heater coil?
I don't know why the vent would not open for the defrost, but it may be related to the fact that your heater core is blown. If your getting nothing but cold air out of the vents when the heat is on, your core is finished and if the core is finished then it is likely related to your vent not opening/switching. Something''s wrong with your heating either way.
