2. If continuity is not as specified, replace the switch
or replace the light(s).
Defroster switch
1. Turn the ignition switch ON.
2. Push the defroster switch to ON, and check the
lights for lighting.
3. If the lights do not light, replace the lights.
4. Check that the switch goes off after 15 min from
switch ON.
5. Check the voltage between each terminal and a
body ground.

6. If the voltage of "d" terminal is 12V with switch off
but not OV with switch on, replace the defroster
switch.
If the voltage of "d" terminal is not 12V with switch
off, trouble is in defroster relay or harness.
If the voltages of the other terminals are not cor-
rect, trouble is in the other parts or harness.
