The AC blows warm air on the drivers side. I pulled the vent door actuator, it wasn’t moving, however, I moved the gear by hand and found that I could not get the air on the driver side to be cool like the other side (or as it used to be). I have been unable to find anything to explain why I was not able to make the driver side cool again. Anyone know the design and something that could account for this problem?
I looked for a heater control valve thinking something should shut off the hot air going to this area, found none. Figured looking up control valve parts would show something for sale that would give me a hint (besides not seeing any control in the engine compartment for this) - because it makes sense that you’d completely kill the heat when you are using the AC. I can’t find anything. I’m thinking maybe the vent actuator isn’t dead but whatever runs it also runs some sort of heat shutoff and THAT is what is not working - but am unable to find anything to explain this.
Anyone know this beast and what I should be looking for? A relay, control, fuse, another vent door? The control is simple, after pulling the actuator, moving the gear/door back and forth is a snap, real hot when I swing it one way, still warm when I swing it the other, so replacing the actuator wouldn’t make it cold. Help? Thanks!!
