Full Installation Tutorial:

Safety glasses should be worn at all times while performing this procedure.

Step 1:

OEM upper glass uses a slotted design. Angle the upper glass up as far as it goes. Then, place thumbs on the bottom of the upper glass and push upward toward the top of the mirror.

Step 2:

Angle the upper glass down and slide the glass off the rest of the way.

Step 3:

Remove the signal on glass and defrost connections from the upper glass.

Step 4:

If the back of your upper glass looks like this, you’ve snapped off part of the OEM mount onto the back of your glass. This mount will need be removed and installed onto your mount before the new Boost Auto Parts glass can be installed.

For instructions on how to do this, refer to our install video or technical manual 

If the back of your glass looks like this, refer to the steps below for further instruction.

Step 5:

Install the signal on glass and defrost connections onto the new upper glass provided by Boost Auto Parts.

Step 6:

Stabilizations pins must be installed onto your new upper glass. If you are using your old pins, slide the old pins out of your old upper glass.

Step 7:

Line up the 3 stabilization pins with the 3 guides on the mirror. If you purchased new pins, or are using the old ones, slide the pins into the 3 slots on your new upper glass.

Step 8:

All stabilization pins must slide on the inside of the 3 guides as shown.

Step 9:

Tuck the signal on glass and defrost wires away from the center of the mirror.

Step 10:


The tabs on the motor mount must be aligned with the slots on the back of your upper glass.

Step 10:

With the mount tabs and slots aligned, place your fingers on the top of the glass and push down toward the bottom of the mirror to slot the glass into place.

Your Installation is now complete!
