Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Provide any existing diagnostic findings for the door-lock system and clarify whether the locks could still be operated manually.
Source: Original question and visible replies. Owner reports and other participants' experiences are distinguished. Next steps are editorial requests for clarification or existing diagnostic findings, not a verified repair procedure or an independently confirmed component diagnosis.
Power door locks not working
The owner of a 1991 Honda Accord reported that none of the power door locks operated. Moving the switch produced clicking from the controller. In a follow-up, the owner reported power at the switch and clicking relays, but no actuator operation.
Reported outcome: No confirmed diagnosis, completed repair or resolution was reported.
Power at the switch and clicking relays do not establish what reached each actuator. The reply suggested an actuator problem, but no findings confirmed a failed actuator, controller or wiring connection.
