WINDOW REPLACEMENT

If a glass is cracked but still intact, it should be
crisscrossed with masking tape to reduce the risk of injury
and/or damage to the vehicle. If a crack extends to the edge
of the glass, mark the door with a piece of chalk at the point
where the crack meets the weatherstrip. Later, when exam­
ining the flange of the opening for a cause of the crack, start
at the point marked.
It is important that the cause of the crack be determined
and the condition corrected, before the new glass is
installed. The cause of the crack may be an obstruction or
high spot somewhere around the flange of the opening;
L00108
cracking may not occur until pressure from the high spot or
obstruction becomes particularly high due to winds,
B
extremes of temperature, or rough terrain.
Remove or Disconnect (Figure 44)
CAUTION: Always wear heavy gloves when han­
dling glass to minimize the risk of injury.
1. Weatherstrip seal by running a putty knife between
the flange and the weatherstrip (inside and outside
the door).
• Have an assistant outside the cab by the
window.
2. Weatherstrip and glass from the flange.
• Force the weatherstrip from the flange from the
inside with a putty knife.
