Santa Fe & Sonata

Battery voltage is applied to power window relay at all times through power window fusible link (30-amp) located in engine compartment junction block, to the main switch assembly through relay's closed contacts. Power window relay operation is controlled by the ETACS control module based on window operation request. When a switch in the main switch assembly or 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 main switch assembly. The direction motor turns depends on battery voltage polarity.
