Heating stopped working after my battery died.

Hey ya'll couple weeks ago my battery died after I accidentally disconnected one of my seat warmer plugs when putting a panel back (pictured below). Now I can't get hot air. A/C works perfectly. There's also a 40 second-ish delay for the blower motor to turn on after the car starts.

When I ran tech stream it threw me this code:

(B1446) Air Mix Damper Control Servo Motor Circuit (Driver Side)

Spent a couple of hours taking off the drivers side lower dash panels and, saw that one of my actuators wasn't moving when changing the hot/cold air settings on the control module. When I turn on the A/C I get good cold air flow through all the vents. Just the heating that's having issues.

I checked the fuses underneath the drivers side dash, and non have seem to popped.
I tried disconnecting the battery for 10 minutes and seeing

Is there something else I may have accidentally disconnected?
Are there any relays that may have gotten stuck when the battery died?
Any ideas to what else I can do to try and fix this, without taking it into the mechanic?

 

If your manually open the servo vent, i assume you get warm air flow? Is so check the voltage level at the servo, if present then replace the servo.

 

That one on the left is tough. It has two servo motors and a lot of gears and arms. I believe the upper motor is the mode and the lower is the blend. If you are luchy, it is just that motor. If the motor is not moving (watch the center area) just replace that. If the motor is moving,it is likely broken plastic parts and that whole assy needs to be replaced.
