2015 Silverado 1500 4x4 Wiper Switch Fault: U0073, U0077, U0126 Causes & Fix for Blinker and Steering Assist Failure

My 2015 Silverado 1500 4x4 now only has wipers working at high speed — no intermittent, slow or medium settings. All other functions operate normally. After replacing the wiper/blinker switch with a new one, I noticed that blinkers and flashers have completely stopped working. The dashboard now shows 'Steering Assist Reduced' and 'Traction Control Disabled,' as if the entire steering column has lost power. Diagnostic codes detected: U0073, U0077, U0120, U0151, and C0710 — all linked to the wiper switch. This suggests a communication or signal failure originating from the switch, possibly affecting multiple systems via shared wiring or control modules. I’ve already taken it to the dealership service department, but they are unresponsive and unwilling to assist further. Is there a possible reset procedure that could clear these codes and restore functionality? The issue seems severe — all this happening after a simple switch replacement — so I suspect either a faulty installation, wiring conflict, or a system-level reset is needed. Any insights from owners of 2015 Silverado 1500 4x4 with similar issues? Can these codes be cleared via OBD-II or a specific vehicle-specific reset?
