I have a 2005 Saab 9-3. The heater stopped blowing hot air. The fan works fine, the thermostat works, the pipes going to the heater core are hot. I took the heater control panel out and the heat control **** is in place. Not sure what else to check. I read somewhere about a Blend Door that controls the heat but I am not sure where to locate that in my Saab.

Any ideas? I live in MI and IT IS COLD UP HERE!!!

Any help would be much appreciated.

 

Is it automaic climate control or manual?
