OPERATION
The AM and FM signals are received via isolated
unheated lines along the top of the rear window.
NOTE: If aftermarket window shading is added, it
cannot be of the metallic type. Metallic type window
shading can cause poor radio reception.
NOTE: If an accessory cellular phone glass mount
antenna is installed, it should only be installed so
as to avoid contact with any of the rear glass grid
lines.

DIAGNOSIS AND TESTING - REAR WINDOW
ANTENNA MODULE
NOTE: Due to a capacitor integral with the coaxial
cable, the coax cable can not be tested. The conti-
nuity test between the center pin of the coax to the
antenna does not apply. An ohm meter check to the
center pin of the coaxial cable will falsely indicate
an open circuit. The coaxial shield to ground test
can be performed. Verify coaxial cable performance
by using a known good cable.
