You have more than 1 issue, as I am sure that you know, so the best thing to do is to start with the electrical wiring diagram for each system and start testing the circuits and components. As for the AC, you will need an AC Diagnosis. here is a site for the wiring diagrams.

could the climate control box be bad and keep the ac from working??
door lock problem solved (duh) no fuse in it.
