Tucson electric seat failure
Summary of the thread
A 2013 Hyundai Tucson experienced a failure with the passenger electric seat, which was completely non-functional despite the fuses being intact. The issue was traced to a weak battery, which, although it appeared to start the car fine, was not providing sufficient power for the seat's electrical system. Replacing the battery resolved the problem, restoring the seat's functionality.

Interesting. The battery seems okay, starts the car fine, but I haven't actually load tested it or anything. How did you figure out the battery was the problem on your Volvo?

On the Volvo, the diagnostic system specifically pointed to low voltage affecting the seat module. Given your Tucson's mileage (166402 km), it might be prudent to have a professional check the battery's capacity. These systems are sensitive. If not the battery, inspect the seat switch, seat harness, and seat wiring.

It WAS the battery! Even though it seemed fine, a proper test showed it was on its last legs. A new battery sorted the seat out. Cost me 290€ at the workshop. Thanks for pointing me in the right direction!

I had a similar headache with my 2016 Volvo XC60. Same symptoms – electric seat kaput, error codes galore. In my case, a heavily discharged or defective battery was the culprit. Have you checked your battery's health? A weak battery can cause all sorts of electrical gremlins.
