If the mirror fails to work properly, check for an open or high resistance in the wire between the connector and the mirror holder. If the wire is OK, replace the power mirror actuator (see POWER MIRROR ACTUATOR REPLACEMENT ).
Defogger Test
Check for continuity between power mirror 13P connector terminals No. 4 and No. 12. There should be continuity. If there is no continuity, remove the mirror holder (see MIRROR HOLDER REPLACEMENT ), and check for an open or high resistance in the wire between the power mirror 13P connector and the mirror defogger terminals (A). If the wire is OK, replace the mirror holder (see MIRROR HOLDER REPLACEMENT ).
