SUBJECT:
ELECTROCHROMIC REARVIEW MIRROR (DD8) VIBRATION (REPLACE MIRROR)
MODELS AFFECTED:
1993 PARK AVENUE/ULTRA
Some 1993 Park Avenue or Ultra models may exhibit a rearview mirror vibration when equipped with the electrochromic mirror (DD8). A mirror, if removed for some reason, may also exhibit a vibration upon reinstallation due to a loss of spring tension.
To repair a comment of electrochromic rearview mirror vibration, replace the mirror with new part number 25618599. The retention spring in the mirror base has been stiffened on this part providing a tighter fit to the mirror support to eliminate vibration.
