I would start by checking the LT doors circuit breaker in the instrument panel fuse block to be sure this is not tripped. This circuit breaker provides power to all of these components.

Sorry for the delay!

Is there power to the power mirror switch and door lock switch on the drivers side when this happens?
Customer: replied 6 years ago.

Not on the drivers side but will still operate passangers mirror window and lock from drivers side

From what your telling me, it really sounds like a bad drivers door module. I would double check this by checking all of the powers and ground as well as the other signals going into this module before you replace it just to be sure.
