Front Door Glass: Adjustment

NOTE: Before adjustment, ensure that all adjusting bolts of stabilizer, upper stopper, and sash are loose and door glass is raised so that it is in contact with weatherstrip.

Temporarily tighten one adjusting bolt on one side of rear sash at the midpoint of slotted hole in the inner panel.
Temporarily tighten regulator B-channel in a position slightly lower than midpoint of slotted hole.
Lower door glass 10 to 15 mm (0.39 to 0.59 in) from fully closed position. While applying outward pressure of 44.1+/-5.0 N (4.5+/-0.51 kgf, 9.9+/-1.12 lb) (F) to upper edge of glass above midpoint of two outer stabilizers, press inner stabilizer until it just touches the glass, then secure it.

After stabilizer adjustment, carry out glass crimp adjustment. First, visually ensure positional relationship between retainer & molding and glass of the roof side, and then begin with rear sash adjustment. Adjust two adjusting bolts alternately step by step to obtain dimensions shown below (cross-section A).
NOTE: If two nuts are loosened at the same time, sash moves back and forth. Therefore, when one nut is adjusted, secure the other.
Make the same adjustment of two adjusting bolts of rear sash.

Make adjustment of front sash in the same manner as that of rear sash.
CAUTION: Although front and rear sashes must, as a rule, be adjusted in the same manner, in some door installation, the adjustment in a different manner may be required. However, adjustment of one sash to the maximum amount and the other to the minimum amount is not permitted. Such adjustment may result in application of excessive load to regulator.
After adjustments, tighten nuts.
After adjustment of glass, if there is a gap between outer lip of gusset and glass surface, adjust the gap with adjusting bolt (A) in lower fitting part of gusset to prevent generation of wind noise.
During adjustments, loosen other three clamping bolts.
