Mirrors: Description and Operation

INTRODUCTION

Power Outside Mirror Switch:

Power mirrors are controlled by a single switch located on the driver's door. The switch has a rocker buttons mark L (left) and R (right) for mirror selection and four buttons for mirror direction movement.

The motors which operate the mirrors are part of the mirror assembly and cannot be replaced separately.

The vehicle is equipped with an Ignition-Off Draw Fuse which is used when it is originally shipped from the factory This fuse is located in the Junction Block and helps to prevent battery discharge during storage when disconnected.

This fuse is included in the power mirror circuity and should be checked if the mirrors are inoperative.

SYSTEM OPERATION
Heated mirror
Heated mirrors are available with Power Mirrors and Rear Window Defogger only. The heated mirror is controlled by the rear window defogger switch. Only time that the heated mirror is on is when the rear window defogger is on. The mirror should become warm to the touch.

CIRCUIT OPERATION
Day/Night Mirror
Power for the automatic day/night mirror is supplied by circuit G5. This circuit is protected by a 5 amp fuse located in cavity 14 of the junction block. Power for the fuse is supplied on circuit A21.

The A21 circuit connects between the ignition switch and the junction block. Circuit A21 is HOT in the START and RUN position only.

Power for the A21 circuit is supplied by circuit A1 from the Power Distribution Center (PDC). This circuit is protected by a 20 amp fuse located in cavity A of the PDC.

Ground for the mirror is provided on circuit Z2. This circuit terminates at the Airbag Control Module (ACM) bracket.

The mirror receives an input on circuit L1. This input is used to tell the mirror when the vehicle is placed in REVERSE. The L1 circuit is spliced in with the back-up lamps.

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 Ignition-Off Draw (IOD) fuse located in the junction block cavity 13. This fuse also supplies power for the radio, interior lamps and other components. Grounding for the power mirrors, along with power door locks and A/C Heater control, is provided through the Z1 circuit, which attaches to the instrument panel left side cowl.

The power mirror switch uses a Light Emitting Diode (LED) located in the switch for illumination. Power for the LED is supplied on circuit G5. The G5 circuit is protected by a 5 amp fuse located in cavity 14 of the junction block. This fuse is HOT in the START/RUN position only

Ground for the LED is supplied on the Z1 circuit. The termination point for the ground is at the instrument panel left side cowl.
