A/C blend door no power 99 expedition
I have a 1999 expedition with electronic climate control for wich the blend door doesn work at all, so I decided to replace the blend door actuator after hours of strugle i finnaly got to it and unplugged the old one connected the new one, and tried the temp control buttons (red and blue) up and down, no movement whatsoever in the actuator eather onl one or new one. I do not have a wiring diagram to figure it out, wonder if anyone else had this problem, could it be a control head gone bad?? There is no fuse listed for the control actuator itself so i figured it must be a control head???
