S40 Wiper Failure

I had a similar problem with my S40. Before you jump to replacing the motor, have you checked the cable and plug connections to the wiper switch? Sometimes those can become loose or corroded, causing intermittent or complete failure. Is your turn signal working correctly?

Interesting! No, I haven't checked the cable or plug connections specifically. Where exactly are they located? Do I have to take apart the whole steering column to get to them? That sounds like a pain. And yes, the turn signals are working just fine, which makes this even stranger.

The connections are indeed located near the steering column, which means some disassembly will be required. Given that the turn signals are functional, and you have an error code, a defective cable or plug connection is quite probable. At this point, I would recommend a visit to a workshop. The repair cost is relatively low; in my case, it was 95€.

Okay, thanks a lot for the advice! I'll check the connections first, but it sounds like a trip to the workshop is inevitable. At least I have a better idea of what to expect now. Hopefully, it's just a loose connection and nothing too serious. I appreciate you sharing your experience; it's a huge help!
