Just finished changing the clock spiral in my 04 SL55, had issues with steering wheel buttons not working and horn blasting when steering turned to full lock position in either direction.
Now my turn signals will not self cancel, they do blink and if you use the lane change signal feature it does cut out after blinking the signals 3 or 5 times.
Everything else works, wipers, washers, cruise, accel and decel for cruise.

While travelling straight down the road, the steering wheel is centered.

No I have not hooked it up to my SDS, planning on doing that this weekend.

Any help would be greatly appreciated.
