Mystery Switches
My 2011 T&C Limited has three switches just in front of the driver's inside door handle. They are marked 1-S-2, but I can't figure out what the do. I can't find anything about them in either the operator's manual or the DVD manual.
Any ideas?

They are the power seat memory buttons..............
The memory system consists of power driver’s
seat, power mirrors and radio presets. The Memory
Seat/Mirror Module (MSMM) is located under the
driver’s seat. It receives input from the following:
driver’s manual 8-way seat switch, driver’s seat
position sensors, PCI bus circuits, and the power
mirror sensors. The module uses these inputs to
perform the following functions: position the driver’s
memory seat, both exterior mirrors (during
recalls), and send/receive the memory system information
over the PCI bus.
The Memory Set Switch is wired to the Body
Control Module (BCM). When a button (either #1 or
#2) is pressed on the set switch causes the to BCM
send a message to the MSMM which in turn sends
a motion status messages to the BCM. If the BCM
receives no motion from the MSMM it will send a
recall message to the MSMM and radio (once ignition
is in run or accessory). The MSMM will in turn
position the drivers seat, both mirrors along with
recalling the radio presets. If the drivers seat or
either exterior mirror is inoperative from its own
respective switches, use the service information
and schematic to diagnose the problem. This manual
addresses the memory problems only and it is
assumed there is not a basic component failure.seat, power mirrors and radio presets. The Memory

No, but its a bugger if you happen to use the spare keyfob one day and everything moves, plus your radio stations are not where you left them... :-( I would suggest investing a few minutes in setting both fobs to your own settings for radio, seat pos and mirrors.
Odd there's nothing in the manual. Mine (2004) has a page on how to set and reset and also how to prog the keyfobs to each memory???
