Heated external rear view mirrors may be provided to pre-
vent the mim:;>rs from frosting up in cold weather. A heating
element is installed inside both mirrors and is activated by a
switch located on the left of the driver on the switch panel.
The switch is wired in series with the Coach Heat switch:
therefore. both must be activated before the mirror heating
element will energize. Once energized, the mirror heating ele-
ment is kept at a sustained temperature by a heat regulated disc
thermostat See figure 3-40. A wiring diagram can be found in
section 7 of thi~ manual.
To service the mirror glass or the heating element, refer to
the previously described procedures for servicing the mirror
glass in the nonheated style mirrors.
