Heater kept blowing hot air....

Thanks... That's interesting. There was time when I only had the fan on with temp set at about 70 and AC off. I got cool air much like the outside. I suppose it bypassed the heater core in that situation.

So I had the heater on (AC off) and even after I turned down the temp to 60's, it didn't redirect the air away from the heater core path? I even turned on the AC which blew cold air, but once I turned off the AC, I got hot air again.

I suppose it'd stay on the heater core path until I restart the car so it'd bypass the heater core path?
