Main Switch Assembly: Elantra

If vehicle is equipped with Electronic Time and Alarm Control System (ETACS), battery voltage is applied at all times to power window relay through fuse No. 16 (15-amp) located in passenger compartment junction block. Power window relay operation is controlled by the ETACS module based on window operation request. If vehicle is not equipped with ETACS, battery voltage is applied to power window relay when ignition switch is in ON position through fuse No. 20 (10-amp) located in passenger compartment junction block. Battery voltage is supplied at all times to power window relay for window motor operation through P/WDW fusible link (30-amp) located in passenger compartment junction block. When power window relay is energized, battery voltage is supplied to the main switch assembly through closed relay contacts. When switch in the main switch assembly 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.
