DIAGNOSIS AND TESTING (Continued)
er's chosen position, the Memory Seat/Mirror Module
will attempt to drive the mirror motor only if:
• The closed switch contact was the same as the
desired direction
• Until the lack of a signal seen by the module
shuts off the drive to the motor
The Memory Seat/Mirror Module will shut off the
drive to the desired motor. It is possible that a single
stuck contact could place an opposite mirror or direc-
tion into a series connection. This would run the con-
nected motors at approximately half speed. Replace
the mirror switch assembly to correct this condition.
The 25-way connector at the Memory Seat/Mirror
Module (under the driver's seat) and the mirror
mechanization show that both mirrors use the same
functions. The rheostat for position sensing utilizes
the wire from the module to the mirror as both feed
