Rear Window Replacement
NOTE:. Put on gloves to protect your hands.. Wear eye protection while cutting the glass adhesive
with piano wire.. Use seat covers to avoid damaging any surfaces.. Do not damage the rear window defogger grid lines
and terminals.
1.Remove these items:
. Hatch lower trim panel (see page 20-53). Hatch spoiler (see page 20-99)
Remove these items:
. High mount brake light {see page 22-821. Rear window wiper motor {see page 22-1461
Disconnect the rear window defogger connectors
(A).
4.lf the old rear window is to be reinstalled, make
alignment marks across the glass and body with a
grease pencrl,
Apply protective tape along the inside and outside
edges of the hatch. Using an awl, make a hole
through the adhesive from inside the vehicle at the
corner portion of the rearwindow. Push the piano
wire through the hole, and wrap each end around a
piece of wood,
6. With a helper on the outside, pull the piano wire (A)
back and Jorth in a sawing motion. Hold the piano
wire as close to the rear window (B) as possible to
