Some vehicle circuits use electronic protection that can stop an output when an abnormal condition is detected. The absence of a visibly blown fuse does not prove the protected load and wiring are healthy.
Identify the actual circuit design
Ask the workshop which control unit supplies the function and what fault information it records. Do not assume every inactive output can be restored by a reset or that it has a conventional replaceable fuse.
The underlying load or wiring issue must be investigated before any supported recovery procedure. Repeatedly clearing protection without addressing the cause is not a repair. Provide the failed function, replacement-part history and diagnostic evidence so the specialist can distinguish deliberate protective shutdown from an internal output-stage defect.
