Memory seat not working after battery disconnection

[alicia434]

I recently disconnected my battery and then re-connected on my 2003 Town Car.
Since then the following does NOT work.
1. All driver seat position movements.
2. The adjustable pedals
3. Moving the LH and RH outside mirrors.
4. Drivers heated seat.

On the door panel the following DOES work
1. The illumination light on the heated seat switches.
2. The illumination light on the memory set button.
3. The trunk and fuel door release buttons.
4. All door locks and window switches.
5. The keyless key pad on the outside of the door.

I have checked all fuses.
Need help here.

How long was the battery disconnected? First thing I'd try is to disconnect it again, leaving it off for at least 15 minutes before reconnecting, just to eliminate the possibility of a glitch. Other than that, I hope it isn't your Drivers Door Module. Good luck.

From my experience, your issues point to the Driver's Door Module (DDM). Beware of wrong information that tends to be posted in these car forums. I had people attempt to assist but the result was time wasted. You might be lucky as your car is a 2003 model. Mine was a 2007 model that required a completely different repair process. Most of your problems match mine but mine had many additional issues all controlled by the DDM. Here's a link to my experience and the help from others that was a goose chase.

Make me think when I have trouble with my DDM I may just wire up the accessories to work old school without it and screw the memory functions.

Interesting as you're planning to rewire the car----that should be fun!

Hey, been searching the forum on the DDM, possibly getting a 2004TC that has been diagnosed with a bad DDM. can the 2004 model be "Plug and Play" with a used DDM? I saw that your model required the purchase of a new DDM and new programming. What is the cutoff year for this change? I saw some DDMs used on ebay labelled as 03-04-05 year models...... thanks.
