HEATED WINDSHIELD—CONVERSION TO CONVENTIONAL GLASS
1988-1992 Continentals
Disconnect (-) negative battery terminal.
Refer to the corresponding vehicle’s EVTM to
locate the appropriate Heated Windshield
Control Module (18C531) and Alternator Output
Control Relay/Heated Windshield Relay
(18D414).
Locate the Heated Windshield Control Module
(18C531), unplug connector.
Locate terminal #1 (Figure 1), remove terminal
locking tabs, remove wire/terminal from the #1
terminal location, and re-install terminal locking
tab.
Wrap electrical tape securely around wire
terminal to insulate from contact with an
electrical ground. Fold back wire to harness
and securely tape to harness to prevent
movement. Plug connector back into the
Heated Windshield Control Module (18C531).
Locate the Alternator Output Control
Relay/Heated Windshield Relay (18D414) and
remove the 16 gauge wire with the moulded
insulator cap connected to the “MOD” terminal
(Figure 2).
Wrap electrical tape securely around the
moulded insulator cap to insulate from contact
with an electrical ground. Fold back wire to
harness and securely tape to harness to
prevent movement.
Remove the wire/eyelet end from the terminals
marked “BAT” and “ALT” on the (18D414) relay.
a. Clean eyelet ends to ensure a good
electrical connection.
b. Install both wire/eyelets to the “ALT” stud on
the (18D414) relay (Figure 2). Invert “ALT”
eyelet for proper mating and seating.
c. Torque “ALT” terminal nut to 3.4 N•m (30
lb-in).
d. Apply electrical sealant compound to
connection.
Reconnect (-) negative battery terminal.
The heated windshield is now
deactivated. When pressing the Electrical Heated Windshield “ON” button, the “ON” indicator will not illuminate. Also check for generator voltage at the battery with the vehicle at idle. Voltage should be between 13.0V to
15.0V. If not, see the corresponding vehicle’s
Service Manual for troubleshooting.
