Probably have more questions than answers for you right now.

Are there any codes?

Are any actuator counts above 250 counts?

What are the part numbers and brand of replacement actuators?

Have you used the scan tool to command the movement of the actuators and did they respond?

Check for ignition power on the brown wire at the actuators.

Check for ground at the yellow wire at the actuators.

Use a meter for checking power and ground circuits.
