Mirrors: Description and Operation
INTRODUCTIONPower Mirror Switch:
Electrically operated power mirrors are available on all car lines. The mirrors are controlled by a single switch assembly located on the driver's door trim panel. The push button rocker switch uses L (left) and R (right) for mirror selection and a button to push for the desired direction of mirror movement.
The motors which operate the mirrors are part of the mirror assembly and cannot be replaced separately.
Power Fold Away Mirror Switch:
Right Hand Drive (RHD) vehicles may be equipped with Power Fold Away Mirrors. The mirror is controlled the same way as the Left Hand Drive (LHD) vehicle. The RHD vehicle has an additional switch in the switch pod that controls the folding function of the mirror assembly.
All vehicles are equipped with a Ignition-Off Draw Fuse, and they are disconnected when the vehicles are originally shipped from the factory Disconnecting this fuse will help prevent the battery from discharge during storage. The fuse is located in Power Distribution Center (PDC) refer to the cover for proper location.
This fuse is included in the power mirror circuity and should be checked if the mirrors are inoperative.
The RHD vehicle mirror circuitry is powered from the accessory feed circuit and protected by a 15 amp circuit breaker and power mirror relay. The relay provides for the switching of the mirror. The circuit breaker and mirror relay are located in the inner door panel wire harness.
NOTE: This information covers both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) versions of this model. Whenever required and feasible, the RHD versions of affected vehicle components have been constructed as mirror-image of the LHD versions.
While most of the illustrations used in this information represent only the LHD version, the diagnostic and service procedures outlined can generally be applied to either version. Exceptions to this rule have been clearly identified as LHD, RHD, or Export if a special illustration or procedure is required.
CIRCUIT OPERATION
Power Mirrors
The power mirrors use a single switch located in the left door trim panel. The feed for the system is supplied from the 10 Amp interior lamps fuse located in the Power Distribution Center (PDC). This fuse also supplies power for the radio and interior lamps. Grounding for the power mirrors is done through the Z8 circuit which attaches to the instrument panel left center support, along with power door locks and A/C Heater control.
Switch And Mirror Operation
The power mirror switch has a right and left position. Moving the switch to either of these positions changes the voltage path internal to the switch (i.e.. changes polarity at the motors).
When the switch is moved to the left position and mirror movement UP is selected, voltage is supplied through the P93 circuit and the ground path is through circuit P90. When the DOWN movement is selected the power and ground are reversed.
If a left door mirror movement LEFT is selected voltage is supplied through the P95 circuit and the ground is passed through circuit P91. When the left door minor RIGHT movement is selected the power and ground are reversed.
When the switch is moved to the right position and mirror movement UP is selected, voltage is supplied through the P92 circuit and the ground path is through circuit P90. When the DOWN movement is selected the power and ground are reversed.
If a right door mirror movement LEFT is selected voltage is supplied through the P94 circuit and the ground is passed through circuit P91. When the left door mirror RIGHT movement is selected the power and ground are reversed.
