2003 Mercedes Benz E320 Seat Module Replacement - Parasitic Battery Draw Fix!

[@zslnker]

Passenger power seat wasn't reliable and high idle current draw. I cleaned corrosion off the module circuit board and re-installed. This fixed my problem. Scrub the board with alcohol and a toothbrush.

Nice fix! Thanks for sharing.

[@wyanrard]

Did your work pass the Lab inspection?

[@WJsLifeonaBoat]

The inspector was pleased. Haha.

[@youngjung4361]

May I ask how much you paid at the junkyard? Also the car doesn't draw power anymore?

[@WJsLifeonaBoat]

I was able to get the module for $40 from eBay. This solved my parasitic draw problem.

@@WJsLifeonaBoat thank you!

[@fastlyferacing]

Is the passenger seat interchangeable with driver?

[@WJsLifeonaBoat]

@@fastlyferacing I'm not sure to be honest. On the safe side, I'd say no.

[@aftershock2222]

I think that’s my problem. Can I get by pulling the fuse or the harnesses until I replace the module?

[@WJsLifeonaBoat]

Yes, you can pull the fuse to stop the battery drain.

[@therealmrprice8952]

hey having this problem on my E320 where was that fuse located at?

[@brianhuh6170]

No SRS light on the dash after installed ?

[@WJsLifeonaBoat]

For me it was plug and play. I can't guarantee this result but from what I read it was just a swap, and the results coincided.
