Power Window Master Switch Input Test
Turn ignition off. Remove driver's door panel. Disconnect power window master switch connector(s). Inspect connector(s) and terminals for damage, corrosion and proper fit. Repair as necessary and recheck system operation. If connector(s) are okay, using a DVOM, perform appropriate power window master switch input test. See Fig 1 . If all input tests are okay and power windows still do not operate properly, replace power window master switch.
