1. Position the tailgate cylinder lock switch (4) onto the back of the lock cylinder (3) with the wire harness 

oriented toward the bottom.  

2. Position the washer over the switch.  

3. Install the retainer (2) clip onto the pin on the back of the tailgate lock cylinder. Be certain that the center 

tab of the retainer is engaged in the retention hole on the lock lever.  

4. Install the trim panel. Refer to INSTALLATION .  

5. Connect the battery negative cable.

DESCRIPTION 

POWER MIRRORS

The power operated sideview mirrors allow the driver to adjust both outside mirrors electrically from the drivers 
seat by operating a switch on the driver side front door trim panel. 

AUTOMATIC DAY/NIGHT MIRROR 

DESCRIPTION 

AUTOMATIC DAY/NIGHT MIRROR SYSTEM 

The automatic dimming inside day/night rear view mirror system is a completely self-contained unit that 
replaces the standard equipment inside rear view mirror. This system will automatically change the reflectance 
of the inside rear view mirror to protect the driver from the unwanted headlight glare of trailing vehicles while 
driving at night. The automatic day/night inside mirror receives ignition switched battery current through a fuse 
in the TIPM, and will only operate when the ignition switch is in the On position. 

The automatic day/night mirror sensitivity cannot be repaired or adjusted. If any component of this unit is 
inoperative or damaged, the entire automatic day/night inside rear view mirror unit must be replaced.

AUTOMATIC DAY/NIGHT MIRROR SYSTEM 

The automatic day/night mirror switch allows the driver a manual control of whether the automatic dimming 
feature is operational. This switch is a momentary rocker-type switch located on the lower rear-facing surface of 
the mirror housing. When Auto is selected, a Light-Emitting Diode (LED) on the mirror housing just to the right 
of the switch illuminates to indicate that automatic day/night mirror is turned on. When Off is selected, the LED 
is turned off. The mirror also senses the backup lamp circuit, and will automatically disable its self-dimming 
feature whenever the transmission gear selector is in the Reverse position. 

A thin layer of electrochromatic material between two pieces of conductive glass make up the face of the 
mirror. Two photocell sensors are used to monitor light levels and adjust the reflectance of the mirror. The 
ambient photocell sensor faces forward, to detect the outside light levels. The headlamp sensor is located on the 
mirror housing just to the left of the switch and facing rearward, to detect the light level received at the rear 
window side of the mirror. When the difference between the two light levels becomes too great (the light level 
received at the rear of the mirror is much higher than that at the front of the mirror), the mirror begins to darken.

DIAGNOSIS AND TESTING 

AUTOMATIC DAY/NIGHT MIRROR 

For complete circuit diagrams, refer to the appropriate wiring information. 

1. Check the fused ignition switch output (run/start) fuse in the junction block. If OK, go to step 2. If not 

OK, repair the shorted circuit or component as required and replace the faulty fuse.  

2. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output 

(run/start) fuse in the junction block. If OK, go to step 3. If not OK, repair the open fused ignition switch 
output (run/start) circuit to the ignition switch as required.  

3. Disconnect the overhead wire harness connector from the automatic day/night mirror connector 

receptacle. Check for battery voltage at the fused ignition switch output (run/start) circuit cavity of the 
overhead wire harness connector for the automatic day/night mirror. If OK, go to step 4. If not OK, repair 
the open fused ignition switch output (run/start) circuit to the fuse in the junction block as required.  

4. Turn the ignition switch to the Off position. Check for continuity between the ground circuit cavity of the 

overhead wire harness connector for the automatic day/night mirror and a good ground. There should be 
continuity. If OK, go to step 5. If not OK, repair the open ground circuit to ground as required.  

5. Turn the ignition switch to the On position. Set the parking brake. Place the transmission gear selector 

lever in the Reverse position. Check for battery voltage at the backup lamp switch output circuit cavity of 
the overhead wire harness connector for the automatic day/night mirror. If OK, reconnect the overhead 
wire harness connector to the automatic day/night mirror connector receptacle and go to step 6. If not OK, 
repair the open backup lamp switch output circuit as required.

6. Place the transmission gear selector lever in the Neutral position. Place the automatic day/night mirror 

switch (2) in the Auto (LED (1) next to the switch is lighted) position. Cover the forward facing ambient 
photocell sensor to keep out any ambient light. 

7. Shine a light into the rearward facing headlamp photocell sensor (3). The automatic day/night mirror 

should darken. If OK, go to step 8. If not OK, replace the faulty automatic day/night mirror unit.  

8. With the mirror darkened, place the transmission gear selector lever in the Reverse position. The 

automatic day/night mirror should return to its normal reflectance. If not OK, replace the faulty automatic 
day/night mirror unit.

REMOVAL

NOTE:

The ambient photocell sensor must be covered completely, so that no light 
reaches the sensor. Use a finger pressed tightly against the sensor, or 
cover the sensor completely with electrical tape.
