REPLACEMENT OF REAR COMBINATION LIGHT
LENS
1. Use a hot air blower to soften the "hot melt" (bond-
ing agent) around the lens.
86U14X-077
2. Remove the lens from the light housing by push-
ing the rear of the lens with a hammer handle or
round bar.
76U14X-034
3. Heat the light housing, and remove the "hot melt"
and any fragments of the lens.
Note
a) The "hot melt" should be reused if
possible.
b) If the "hot melt" can be reused, the follow-
ing step is unnecessary.

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

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.
