2000 Dodge Neon- Heater

I just had the thermostat replaced but it still not blowing hot air. Apparently they also changed the gasket and they flushed it. Any ideas of what else could be wrong??

Sure, if the hoses going into the firewall are hot going in and cold going out and the coolant system is full.........your heater core is stopped up

you can backflush it by disconnecting hoses and running water thru it in the opposite direction of normal flow.if both hoses are hot then check inside car for blower system vent doors control failure.they are either vacumn or wire controled.was it working previously?
