Seat Tarraco Hybrid Power Window Issue

Sounds like you might have a similar issue to what I experienced in my Tarraco. The inability to operate the power windows and a stored error definitely rings a bell. Before jumping to conclusions, have you checked the door panel wiring harness for any signs of damage or loose connections? Sometimes, a simple disconnect can cause these symptoms. Also, when you say 'error memory', what specific error code are you seeing?

I haven't checked the door panel wiring harness myself, to be honest. I'm not really comfortable messing with the electrics. As for the error code, I can't remember exactly what it was, but the diagnostic tool at the garage pointed to an issue with the window control circuit. Could it really be just a loose connection? I assumed it was the window motor itself.

A loose connection is always worth checking, but given the error code points to the window control circuit, and the fact that all windows are affected, a faulty power window switch is a strong possibility. It's like when a fuse blows, sometimes it's just one circuit, sometimes it takes everything out. Since you are not comfortable with electrics, my advice would be to get a mechanic to confirm the switch is faulty. It is very possible that it is a faulty switch. Replacing the switch is fairly straightforward, and 200€ seems like a reasonable price, assuming it includes the switch itself. If the garage is confident in their diagnosis, I'd say go for it.

Thanks for the info! I took it to a local garage, and they confirmed it was a faulty window switch. They replaced it, cleared the error memory, and now the power windows are working perfectly again. Cost me around 200€, just like you said. Appreciate the help!
