Seatbelt buckle switch failure and bypass

Symptom: the seatbelt warning chime keeps sounding even after the belt has been fastened, and it may take 2–3 attempts at re-buckling before it clears ¹. Cause: the end-cap switch inside the buckle lock (concevik/концевик) is failing/wearing out and stops reliably reporting the "fastened" state ².

Bypass fix (not a proper repair). Cut the two wires that run to the end-cap switch inside the buckle and splice them together directly. This makes the system permanently read the belt as fastened regardless of actual buckle state — it eliminates the warning chime entirely, but also defeats the seatbelt reminder function, so it's a workaround rather than a fix and disables a safety feature ².
