Subject: SERVICE MANUAL UPDATE - SECTION 10 INSIDE REARVIEW MIRROR ADJUSTMENT (ADDITIONAL SERVICE PROCEDURE)

Models

Affected: 1989 LEMANS
Add the following adjustment procedure to the 1989 Pontiac LeMans Service Manual, page 2T-7.

This vehicle's inside rearview mirror pivots at two places; the ball-and-socket mirror pivot and the fore/aft hinge pivot located at the window base. Only the fore/aft hinge pivot is adjustable. If the ball-and-socket pivot ceases to function properly, replace the mirror assembly.

Adjustment

* Insert a 3mm Allen wrench into the adjustment set screw on the right side of the window-base pivot.

* Loosen the set screw and move the mirror to the desired position.

* Tighten the set screw to retain this mirror position.

HELPFUL HINT

It is possible to leave this set screw slightly loose to allow the driver to adjust the mirror while driving. However, over time the screw may loosen further, causing the mirror to drop below the desired adjustment height. If the vehicle's owner requests this type of adjustment option, instruct him or her on how to retighten the set screw should it loosen in the future.
