Just bought my daughter an 03 V6 convertible as a daily school car. The drivers door lock actuator is not getting power. The actuator was replaced and I can get it to operate using wire and a cordless screwdriver battery. I can get 12volts at the drivers door lock switch. The passengers lock works fine from the switch and remote. It does have the Ford factory alarm. The drivers lock only works manually. Where else should I look?

First post and working through the variety of used car issues.
