More than likely this is a relay issue as you have a relay for the front and rear doors, so we need to check the voltage coming out of the relay.
Here is a guide that will help with testing the relay:

I am attaching the wiring diagram below which will help with this.
The easiest way to check this is to see if you have power at the actuator or leaving the relay so let me know if you have questions on this and then we can go from there depending on what you find.
