Replacing the exterior mirror glass
It is unnecessary to replace the entire outside rearview mirror assembly when the mirror glass is damaged or broken. Replacement mirror glasses are available from Mopar.
NOTE: SOME REPLACEMENT MIRROR GLASS/HOLDER ASSEMBLIES ARE PACKAGED WITH REMOVAL/INSTALLATION INSTRUCTIONS WHICH SHOULD BE FOLLOWED, BUT IF NO INSTRUCTIONS ARE PACKAGED WITH THE REPLACEMENT GLASS/HOLDER THE FOLLOWING PROCEDURE SHOULD BE USED FOR THE WJ:
WARNING: ALWAYS WEAR EYE AND HAND PROTECTION WHEN SERVICING THE MIRROR ASSEMBLY. FAILURE TO OBSERVE THESE WARNINGS MAY RESULT IN PERSONAL INJURY FROM BROKEN GLASS.
1. With damaged mirror still on vehicle, position mirror glass to the full down position and center it from side to side.
2. Position a wide leverage device (a large flat blade screwdriver works best) between the bottom edge of the glass/holder assembly and the inside of the mirror housing/shell. If using a screwdriver lay a rag underneath it to prevent pry marks on the mirror housing.
Mirror glass removal
3. Firmly apply pressure in an upward direction until glass assembly disengages from the backing plate in the mirror housing/shell. The glass housing can be stubborn to remove. Pry a little on one side first, and then the other side, repeating this a few times will gradually loosen the housing and it will pop off.
4. Disconnect all wire terminals from the glass assembly if equipped. There is one connector for the power function and two spade connectors for the heated function.
Glass assembly installation:
1. Connect all wire connectors and terminals to the back of the replacement glass assembly. The two wires for the heated feature can be reattached to either terminal (the wires are both black).
2. Locate the four snap tab cavities on the back side of the glass asssembly and align them with the four corresponding snap tabs that are on the front of the round backing plate inside the mirror housing. If the backing plate position has been changed make sure that it is in its fully downward position.
3. Firmly apply forward and downward pressure to the mirror glass assembly until it locks in place into the backing plate. Correct assembly will result with a firm click as the four tabs simultaneously snap into place. The glass should exhibit even gaps around the mirror housing when complete and in the centered position.
4. Pull lightly on each corner of the glass assembly to ensure all four snaps are engaged and that there is no freeplay. You can manually push on the glass to rotate its position in order to better access the corners.
5. Check all power/dim functions of the mirror.

Cleaning the power mirror memory contacts
In some situations the power mirrors may have difficulty adjusting to their proper positions or remembering their location. Sometimes (but not always!) this is due to dirty components or poor contacts on the potentiometer circuit board inside the housing. To perform the following procedure to clean and check the contacts, the mirror needs to be disassembled. The circuit boards, worm gears and pivot arms need to be cleaned and new grease applied.
2. Remove the circular mirror backing plate. It is attached to the top of the motor housing with four locking clips, as shown in the photo above. It is also attached into a socket at the center. A tiny flat blade screwdriver works best. Just insert it into each of the 4 slots and pry inward (so as to pry the tab outward) while slightly pulling up on the plate edge at the clip location. You will feel the clip unsnap. Next pull on the plate to unsnap it from the center socket. This takes a bit of a pull to release it. Clean both sides of the plate and re-apply waterproof grease to the center hole on the back side.
3. Remove the rubber boot. It is pressed over each of the four arm ends. Remove carefully so as to not tear the boot. Clean the boot. If you have some “rubber cleaner” or reconditioner (like what is used to recondition audio pinch rollers for example) apply to the front and back. There are automotive rubber reconditioners available as well.
6. Using isopropyl rubbing alcohol (or electrical contact cleaner) and a swab, very carefully clean the contact ends on each pivot arm. Commercial wood stick swabs work better as they are tightly woven and will not catch on the contacts. The contacts are fragile and can bend easily so it is best just to lightly “dab” the sharp-pointed ends. You may also want to carefully pry them out just a tiny bit so as to make stronger contact to the potentiometer circuit board when they are reinstalled. A detail photo of the arm and contacts is shown above. Clean the entire arm as well, grease will be reapplied to the bottom and the gear edge before they are reinstalled.
7. Remove each potentiometer circuit board and lift it straight up out of its plastic “socket”. The boards should be cleaned with rubbing alcohol and a cotton swab. Reapply dielectric grease after cleaning and reinstall into their slot. If any of the worm gears have dirt or debri on them, clean those as well and re-apply a waterproof grease. Grease and dirt should be cleaned off all other areas inside the motor housing and then reapplied (the only area that get dielectric grease is the circuit board, all other areas use waterproof automotive grease).
8. Reinstall each pivot arm, starting with the contact end, inserting it at an slight angle. Be careful that the contacts are aligned correctly in place. Without the worm screws in place, put a finger on each end of the pivot arm and “rock” it back and forth, this will confirm that the each arm is seated and pivoting correctly. Lift up the end of the arms and insert each worm gear back into place. Double-check that the worm screws and other parts are all resting in their correct slots.
9. Confirm that all 6 wires that protrude out of the motor housing are set into their individual notches along the edge. Reinstall the housing top cover, checking that it is seated correctly all the way around and set into its location in the mirror housing. Remember that the longer screws are in the center area, shown in yellow circles in the photo for step 4.
10. Reinstall the rubber boot, stretching it over and around each of the four pivot arm ends.
This is an interior blind spot mirror that a WJ owner in Japan installed on his interior “A” pillar. The Jeep is a right-hand drive model, so the mirror shown above is on the driver’s side.

This mirror was designed for the Jeep Commander concept and features a unique wiper system, incorporated into a small round blind-spot mirror. The fold-away mirror also features a heated surface and position memory.
