III. Background

The sliding electrical contact module in the driver's side Power Window Master Switch (PWMS) may experience a "notchy" or sticking feeling during operation.

If commercially lubricants are applied to the switch in an attempt to address the "notchy" or sticky feel, melting or smoking of the switch assembly could occur. Under some circumstances, this could lead to a fire.
