- Ignition on.
Press the switch for the power door mirrors. Move the door mirrors to their limit position.
Can the power door mirrors be maneuvered?
Yes - Intermittent fault
No - Checking for a short-circuit
-------------------------------------------------
Checking for a short-circuit
Check the cable between door control module terminal #27A and power door mirror terminal #7 (both 10 and 16-pin connectors). Check for a short-circuit to supply voltage.
Remedy as necessary.
Try a new power door mirror if the cable is OK.
