Peugeot 406 electric seat failure

Hi, I have a 2004 Peugeot 406 (gasoline engine) with almost 300k km on the clock. Recently, the passenger electric seat stopped working. The error memory has a fault stored, and the seat adjustment is completely non-functional. I checked the fuses, and they seem fine. Any ideas?

Hmm, sounds familiar. I had a similar issue with my old Opel Astra, although that was a completely different setup. The error memory and lack of movement suggest it's getting no power. It could be a faulty seat switch, damaged wiring, or even a failed seat motor, but did you check the battery?

The battery? I didn't consider that, mainly because the car starts fine. But could a weak battery really cause just the seat to fail?

Yes, that's what I found on my Astra. A heavily discharged or defective battery can cause weird electrical issues. Before tearing into the seat itself, check the battery's voltage, and if possible, get it load-tested. If the battery is okay, you will need professional help to identify the error. I would recommend going to the workshop.

Okay, thanks for the tip! I'll get the battery checked out first thing tomorrow. It ended up costing 290€ in the shop, but at least the seat works again!
