Dimmer Switch: Testing and Inspection

Inspection

1. Disconnect the negative (-) battery terminal.
2. Remove the lower crash pad switch (A) from the side crash pad cover by using the scraper.




3. Disconnect the rheostat connector from lower crash pad switch.




4. Check for intensity. If the light intensity of the lamps changes smoothly without any flickering when the rheostat is turned, it can be assumed that the rheostat is normal.
