Best to you.

Principles of Operation
The driver seat module (DSM) is on the controller area network (CAN) communication network. To support several vehicle subsystems, the module permits intermodule and diagnostic tool communications.
The DSM controls the memory driver seat and the passenger memory power exterior mirror. This passenger memory power exterior mirror feature allows the driver to program personalized mirror positions. Once the driver stores a mirror position, the driver can recall the setting by pressing the corresponding memory switch or by using a programmed remote keyless entry (RKE) transmitter. For additional information, refer to Section 501-10 .

How to Diagnose Controller Area Network CAN

Driver Seat Module - Memory Seat
The power driver seat, power outside rear view mirrors and power adjustable pedals are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located on the driver seat track.
This system allows automatic positioning of the driver seat to 2 programmable positions.

• A power driver seat position can be stored at any time. The driver must move the seat to the desired position using the driver seat switch assembly. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2.
• If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory seat position switch (set switch) LED is turned OFF. This also occurs if one of the following inputs is received during the 5-second programming limit:
  • Driver seat control switch
  • Memory seat position switch (set switch)
  • Power adjustable pedal switch

A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position. A position may be programmed at any time.

Easy Entry/Easy Exit
The driver power seat easy entry/easy exit feature can be enabled/disabled. Refer to Section 418-01 or the owner's literature.

This may need to be done with a scan tool

Hello Judy Tatum,

Your drawings are available (free) on-line at BBB Industries
(see below: registration required)... No TSB (tech service bulletins) address your issue(s).

the fact that two troubles are SIMMULTANIOUSLY failing points DIRECTLY to their common CIRCUIT MODULE...!!
I am suspecting you are having an intermittent (power) issue
with your DRIVER'S Seat memory module (BCM)... 14C708.

If... and only if ...
you ALSO have power seats... AND they still work...
(your fuse is the same 5 AMP for both) ... THEN...
You can cross that main control fuse OFF of the suspect list.

Your vehicle IMMEDIATELY gives 2 different drawings...

There are TWO different OPTIONS... but the DETAILED schematic drawings show every wire color and connector between the mirrors, pedals, switches and That CONTROL MODULE.

MY ANALYSIS would indicate FINDING your module... 14C708 and carefully checking EACH & EVERY connector COMMON to your pedal control AND your mirror control...

You will find a loose (or badly corroded) one.
((comment me back... I will tell you how to clean & refurbish)).

Fear not your door sills, kick panels and carpeting come up pretty easily... Your car pops together really nicely.

My very best suggestion is to beg, borrow or buy the FACTORY+WORKSHOP+MANUAL... in particular... electrical is in volume three... Reasonably priced on CD... (I use paper).

Else your...
DRIVER'S Seat memory module... 14C708 needs to be "SPARED-OUT" to test a new/previously-owned one.

(Pictures are illustrative ONLY... VERIFY your own numbers).

Hope this helps!

Driver door or seat module. All of these components are controlled by s module. You'll need a scan tool to properly diagnose.

probably a second fuse . the power seat alone requires 25 amp fuse

have you check fuse and relays. there is a seat memory under the driver's seat

It could be , but to replace it without testing would not be a wise idea . These modules can set DTC'S - diagnostic trouble code's .Having a qualified repair shop check it would be your best bet .
It's called driver seat module .

i have a 05 ford f150 supercrew my power adjustable pedals didnt work my mirrors didnt work n the driver seat didnt work i found the problem i had a broken wire coming out of the #3 fuse block it it was orange with a green stripe it has some heat shrink on it i cut the heat shrink tape and the wire was badly corroded i replace the splice with 18 gauge wire and and everything came back on good as new
