power door locks not working 93 century

Have not had time to check fuzes yet. Did check wipers, work, cigarette lighter works, seat belts indicator engage and and disengage. The car is not equipped with a trunk latch switch but a wire does go back there. It does not appear to be grounded anyplace visible. I pulled out the connector and it is secure. The dome light does not work from the interior switch or the map light switch or from any doors ajar.

Thank you each and everyone for your input. I did do a fuze check. The courtesy light fuze was a bad guy. Everything seems to be working now. Funny, so many things would be attached to one courtesy light, with a 20 amper no less. The break is verily discernible but the meter does not lie and the proof is in the pudd'n. Thanks again for all the help given. Have a grand day.
