Defroster and Heat Controls Do Not Work

To fix the defrost and heat control issues, I replaced the blend door actuator. I started the engine and cycled thru the temperature controls but could not hear or see the actuator working. I removed it and applied 12VDC to it and verified that it worked. Could you please provide the HVAC wiring diagrams so that I can locate the HVAC fuse or troubleshoot the actuator wiring? Thanks in advance.
