DESCRIPTION & OPERATION
Capri and Festiva vehicles are equipped with a 2-speed wiper motor with an optional intermittent system. The Festiva rear wiper uses a single
speed wiper motor. Washer systems for both front and rear washers use pumps mounted near fluid reservoirs.
ADJUSTMENTS
W IPER ARM ADJUSTMENT
Remove wiper arm and blade assemblies from pivot shafts. Turn wiper switch on and allow wiper motor to cycle 2 to 3 times. Turn wiper
switch off to place pivot shafts in park position. Reinstall wiper arm and blade assemblies with tips of wiper blades at specified distance from
lower edge of windshield. See WIPER BLADE ADJUSTMENT SPECIFICATIONS
table. Tighten wiper arm retaining nut to 89-124
INCH Lbs. (10-14 N.m).

TESTING
FRONT WIPER MOTOR TEST
Capri
1. Check WIPER fuse in interior fuse block and replace if necessary. Perform FRONT INTERVAL WIPE MODULE TEST . If
wiper/washer switch and interval module are operating properly, disconnect wiper motor connector. Turn ignition on and place
wiper/washer switch in HIGH position. Measure voltage at Blue/Red and Blue wires at wiper motor vehicle harness connector.
2. If battery voltage is not present, check Blue/Red or Blue wire for open circuit. If battery voltage is present at Blue/Red and Blue wires,
check Black ground wire at wiper motor vehicle harness connector for an open circuit and repair as necessary. If Black ground wire is
okay, replace wiper motor.
Festiva
1. Place wiper in any position other than park. Remove WIPER fuse. Disconnect wiper motor electrical connector. Using an ohmmeter,
check for continuity to ground at motor case. Continuity should exist. If continuity does not exist, replace or repair wiper motor ground
strap or wire.
2. Check for continuity to ground at Blue/Black terminal of wiper motor. Continuity should exist. If continuity does not exist, replace
wiper motor.
FRONT INTERVAL WIPE MODULE TEST
Capri
1. Check WIPER fuse in interior fuse block and replace if necessary. Perform FRONT WIPER/WASHER SWITCH TEST . Access
interval wipe module connector. Interval wipe module is located below instrument panel near console. Ensure wiper switch is in OFF
position. Turn ignition on and measure voltage at Blue/White and Blue/Black wires of module connector. Battery voltage should not be
present. Turn wiper switch to LOW position. Measure voltage at Blue/White and Blue/Black wires of module connector. Battery voltage
should be present.
2. Turn wiper switch to HIGH position. Measure voltage at Blue/White, Blue/Black and Blue/Red wires of module connector. Battery
voltage should be present. Turn wiper switch to INT position. Measure voltage at Blue/White and Blue/Black wires of module
connector. Battery voltage should be present during each cycle. If module does not perform as specified, replace module.
Festiva
Information is not available from manufacturer.
FRONT WIPER/WASHER SWITCH TEST
Capri
Remove lower steering column cover to gain access to wiper switch electrical connector. Using an ohmmeter, ensure continuity exists between
terminals listed in table at specified switch positions. If switch does not test as specified, replace wiper/washer switch. See FRONT
WIPER/WASHER SWITCH CONTINUITY (CAPRI) table. See Fig. 1 .

FRONT WASHER MOTOR TEST
Remove washer fluid reservoir. Remove washer motor from reservoir. Connect fused jumper wire between washer motor terminal that
corresponds with Blue/Orange wire (Capri) or Blue wire (Festiva) and battery positive terminal. Connect other washer motor terminal to
ground. Washer motor should run smoothly. If washer motor does not run smoothly or does not run, replace motor.
REAR WIPER MOTOR TEST
Festiva
1. Place wiper in any position other than park. Disconnect wiper motor electrical connector. Using an ohmmeter, check for continuity to
ground at motor case. Continuity should exist. If continuity does not exist, repair wiper motor housing ground wire.
2. Check for continuity to ground at Blue terminal of wiper motor. Continuity should exist. If continuity does not exist, replace wiper
mo t o r.
REAR WIPER/WASHER SWITCH TEST
Festiva
Remove rear wiper/wash switch. Using a self-powered test light or an ohmmeter, ensure continuity exists between terminals listed in table at
specified switch positions. If switch does not test as specified, replace wiper/washer switch. See Fig. 3
. Also, refer to the REAR
