I looked around a little and don't see what I wanted, so here goes:
The heater in my 04 quit suddenly a few days ago. I was going to put a water pump in it anyway, so while it was out, I flushed out the heater core. It's got great flow and isn't leaking. It switches from defrost to vent to floor perfectly. I crawled under the dash and you can see the actuator moving back and forth like it's supposed to when you turn the knob back and forth from cold to hot to cold again. I noticed that if I put it on defrost it gets really cold. Not near as cold when on vent. So my guess is it's a loose door of some sort in there. Is there a way to get in there and manually move the door so it's always on hot? Then in the spring I could take it apart and put all new stuff in there
