Master Switch Assembly
Battery voltage is applied to power window relay when ignition switch is in RUN position through fuse No. 16 (Elantra and Tiburon), located in passenger compartment fuse panel. On Sonata, battery voltage is supplied, by way of power window fusible link (30-amp) in engine compartment relay box, to the master switch assembly through relay's closed contacts. When either switch in the master switch assembly is operated, battery voltage is applied to the power window motor. The motor is then grounded through the opposite contact in the master switch assembly.
Sub-Switch
When ignition switch is in ON position, battery voltage is applied to the power window relay through fuse No. 16 (10-amp), located in passenger compartment fuse panel. When relay is energized, battery voltage is supplied to the master switch assembly through closed relay contacts. When a sub-switch is operated, battery voltage is applied to the power window motor. The motor is then grounded through the opposite contact in the respective sub-switch and master switch assembly.
