Electricalbeginner✓ OP Confirmed

Problem

After replacing the right door speaker and reconnecting the door panel wiring, the passenger-side power window stopped working from both the passenger switch and the driver-side master switch.

Root Cause

The electrical connector for the window switch had dirty or corroded contact points, resulting in a poor connection after being disturbed during speaker replacement. Disconnecting and reconnecting the plug during the speaker job exposed the marginal condition of the aged contacts.
