This morning I get into my car and stalks are not working. Unfortunately, I noticed it too late so I just did my commute without turning signals - dangerous and stupid endevor in DC traffic.

Turn signal, high beams, cruise control, wipers - nothing works. However, BC button still cycles and automatic wipers also work.

All steering wheel buttons work fine. Instrument cluster lights up when lights are on. Lights work. Emergency flashers work. System check says everything is fine.

I pulled codes and got following:
DSC:
009511 - FGR / ACC steering column switch (LST) implausible - illegal combination with cruise switch

009519 - Wiper switch (SWS) unplausibel - illegal combination with occured in wiper switch.

I tried erasing errors, but they came back immediately.


What the hell could it be? Any advice?

Maybe remove the steering wheel and clockspring to gain access to the stalks. Remove them and clean the contact points.

It seems like the wires might be an issue after all. On the way home, I just shook stalks a bit and everything started working just fine. When I have some free time, I might remove the bottom cover to see if I can fine lose wires causing the issue.
