Chrysler 300M, Dodge Interpid. Manual - part 103
OPERATION
When the memory set/selector switch is depressed,
a resistance signal is sent to the memory heated seat
mirror module via hard wired connections. The mod-
ule than receives this hard-wired input and applies
power to move the power seat track or side view mir-
rors according to the preset position. When the mem-
ory system is in “set” mode a chime will be generated
by the body control module.
See the owner’s manual in the vehicle glove box for
more information on the features, use and operation
of the memory switch.
