WIPER/WASHER SYST EM
1991 ACCESSORIES & SAFET Y EQUIPMENT Ford Motor Co. Wiper/Washer System s
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).
WIPER BLADE ADJUSTMENT SPECIFICATIONS
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 AXLE BEARINGS
Front bearing preload is adjusted during bearing replacement by changing preload spacer. See FRONT WHEEL BEARINGS under
REMOVAL & INSTALLATION.
REAR AXLE BEARINGS
With bearings installed, tighten NEW lock nut to 18-22 ft. lbs. (24-30 N.m) while rotating wheel. Slightly loosen lock nut so it can be turned
by hand. Install a lug nut into axle hub. Attach an inch-pound torque wrench to lug nut at 12 o'clock position. Measure bearing preload.
Tighten lock nut until bearing preload, including seal drag, is 3.5-6.2 INCH lbs. (.4-.7 N.m). Stake NEW lock nut into notch on spindle.
TESTING
POWER BRAKE UNIT
Functional Test
1. Check master cylinder fluid level and hydraulic system for leaks. Place transaxle in Neutral or Park, turn ignition off and apply parking
brake. Pump brake pedal several times to eliminate vacuum from system, and hold pedal in depressed position.
2. Start and idle engine. If vacuum system is functioning properly, pedal moves downward under constant foot pressure. If no pedal motion
is felt, vacuum booster is not functioning properly. Go to next step.
3. Run engine for at least one minute and turn ignition off. Depress brake pedal several times. Booster is okay if pedal stroke is long at first
and becomes shorter with each stroke. If stroke does not shorten, check for a damaged, restricted or improperly connected check va l ve
vacuum hose. Repair and recheck. Go to next step.
4. Restart engine. Depress and hold pedal down. Turn ignition off and wait 30 seconds. Booster is okay if pedal height remains unchanged.
If pedal height changes, check for a damaged, restricted or improperly connected check valve or vacuum hose. Go to next step.
5. Connect a pressure gauge to master cylinder output line. Connect a vacuum gauge to booster and a pedal depression force gauge to
brake pedal. Bleed air from pressure gauge. Start engine. When vacuum gauge reads 19.7 in. Hg, turn ignition off. Watch vacuum ga u ge
for 15 seconds. Booster is okay if vacuum gauge reads 18.7-19.7 in. Hg. If vacuum gauge reads less than 18.7 in. Hg, proceed to next
step.
6. Restart engine. Apply and hold 44 lbs. (196 N) force to brake pedal. When vacuum gauge reading reaches 19.7 in. Hg, turn ignition off.
Watch vacuum gauge for 15 seconds. Booster is okay if vacuum gauge reads 18.7-19.7 in. Hg. If vacuum gauge reads less than 18.7 in.
Hg, proceed to next step.
7. With engine stopped and vacuum gauge at zero, check pressure gauge. Apply 44 lbs. (196 N) force to brake pedal and check pressure
gauge. Booster is okay if pressure gauge reads 256 psi (18 kg/cm
2 ).
8. Remove pedal force and start engine. When vacuum gauge reaches 19.7 in. Hg, apply 44 lbs. (196 N) force to pedal. Booster is okay if
pressure gauge read 768 psi (54 kg/cm
2 ).
Diagnosis
If booster does not function properly, see Fig. 3 .
NOTE:Axle lock nut on right side has left-hand threads. Always install NEW lock nut when rem oved.
NOTE:Inspect all vacuum hoses for holes, collapsed areas and secure connections. Ensure all unused
vacuum ports are capped.

CAUTIONS & WARNINGS
BATTERY WARNING
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off all lights and accessories to avoid damaging the electrical system. Be sure to use
fuse with the correct indicated amperage rating. The use of an incorrect amperage rating fuse may result in a dangerous electrical system
overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning that brake pads need replacement.
CAUT ION: When battery is disconnected, vehicles equipped with com puters m ay lose m em ory data. When battery
power is restored, driveability problem s m ay exist on som e vehicles. T hese vehicles m ay require a
relearn procedure. See COMPUTER RELEARN PROCEDURES
article in the GENERAL INFORMAT ION
section.

WIRING DIAGRAM COMPONENT LOCATIONS
When trying to locate a component in a wiring diagram and you don't know the specific system where it is located, use this handy component
locator to find the system wiring diagram in which the component is located. Then, go to that system and locate the component within the
wiring diagram.
For example, if you don't know the specific system in which the ignition switch is located, look up ignition switch in the wiring diagram
component location tables and go to the appropriate wiring diagram(s) which contain either full or partial views of the ignition switch. The full
view of the ignition switch is located in Power Distribution.
The first listing for the component will be the full or most complete view of the component. Additional listings will be partial views of the
component. Not all components are used on all models.
All components will have a partial view in Ground Distribution and Power Distribution. Data Link Connectors show connecting circuits
between modules. Alternate names for components may be listed in wiring diagram component locations tables.
