The symptom is a diesel-like knock or… Repairs typically run $70-$200. Severity: low.

What is the 1993-1997 Mazda MX-6 Driver's Door Power Window Master Switch Failure (2G)?

The driver's-door master switch on 1993-1997 MX-6s fails independently of the window regulator: the contacts inside the driver's switch burn and corrode, so the driver's window (and often the passenger control from the driver's side) stops responding or works only intermittently… Repairs typically run $20-$350.
