Checking the glove box light switch
1. Check for continuity between terminals "1" And "2" when the button is pressed and the presence of conductivity when the button is pressed. If the conductivity is not as described, replace the switch.
2. Disconnect the connector from the switch and check the circuit on the wiring harness side according to the table.
If the circuit does not match the table, check other elements of the system.
Checking the interior light switch
1. Disconnect the connector from the lampshade.
2. Set the interior light switch to position "ON" and check the continuity between the output "2" And "earth" (see picture).
3. Set the interior light switch to position "DOOR" and check the continuity between the terminals "1" And "2" (see picture).
If the switch does not operate as described, replace it.
Check of the switch of illumination of a back part of salon (models up to 1996)
1. Disconnect the connector from the lampshade.
2. Set the interior light switch to position "ON" and check the continuity between the output "2" And "earth" (see picture).
Checking the trunk light switch
Check for continuity between the connector pin and "earth" when the switch button is pressed (trunk closed), and the presence of conductivity when the button is depressed (trunk open).
If the conductivity is not as described, replace the switch.
Checking the rheostat of the instrument cluster backlight switch
When changing the position of the rheostat handle from one extreme position to another, the resistance should vary between approximately 0 and 4.5 ohms.
