Heater problem
2005 Chevy Aveo 4 cyl Front Wheel Drive Manual 61k miles

I have a 2005 Chevey Aveo that the heater works fine when driving at speed, but when I slow for a traffic like or stop and just idle for any reason, the air begins to turn cold. The blower fan works fine, and this happens when the heat switch is any any position, (vent, vent-floor, floor-windsheild, windsheild only, etc. Any suggestions? Thanks, Bill

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!
Check your thermostat too.
