Heater problem
1996 Subaru V4 All Wheel Drive 250000 miles
----------------------------------------------------------------
My car heater will work just fine while I am driving but the moment I stop and idle it will immediately start blowing cold air. When I start to move again, the heat starts right back up. I did check the coolant level and it is fine. Any ideas?

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!
