Blend door power issue
Hi guys, i have an '03 HD and my temperature side blend door actuator isn't working. I took it out gave it external power and didn't turn so it's shot. I did the same thing with the new one I bought and it turned so I installed it, plugged the clip back in...aaand nothing. I have the digital etac unit and I did the self diagnostic on it and I get codes 49 and 12. From what I can see this is some sort of short. Does anyone know where the other end of this actuator harness goes to? Thanks in advance.

According to my Chilton manual wiring schematic:
The LT blu/pnk wire goes to the fuse panel. Fuse #5.
The other three wires go to the selector switch.
Fuse #5 has power in the run position. Check fuse #5 for power.
