Acclaim L4-153 2.5L SOHC Flex Fuel (1994)
Wipers Failing to "Park" When Switched "Off"
1. Disconnect motor wiring harness connector and clean terminals. Reconnect connector and test motor.
2. If condition persists, set wiper switch to Off position. Disconnect motor wiring connector. Connect a voltmeter to motor ground strap and other
lead to terminal 2 on harness connector.
3. If voltage is not present, check for an open circuit in wiring harness or wiper control switch.
4. If voltage is present, connect an ohmmeter between terminals 3 and 1.
5. If continuity exists, problem is a defective motor.
6. If no continuity exists, problem is an open circuit in wiper control switch or wiring harness.
Rear Wipers
1. Remove lower cover on liftgate.
2. Disconnect feed connector from wiper motor.
3. With ignition switch in On position, check for voltage at blue wire.
4. With both ignition and wiper switches in On position, check for voltage at blue and brown wires.
5. If battery voltage is not present, check fuse, liftgate wiper switch and wiring.
6. With ignition switch in On position and wiper switch in Off position, check for battery voltage between blue and brown wires.
7. If no voltage is present, check ground wire to liftgate switch.
8. If battery voltage is present in steps 3 and 4, replace motor.
Important Information - Read First
The intermittent wipe function is controlled by the body controller, located in the passenger compartment behind the right side kick panel.
To diagnose system malfunctions that do not involve the
delay function, refer to "Standard Front Wipers" in this section.
Excessive or Inadequate Delay
1. Verify delay as follows:
a. Minimum delay is 1/2 to 2 seconds.
b. Maximum delay is 15 to 25 seconds.
2. If there is excessive delay or no variations in delay, remove wiper motor wiring harness while motor is parked in Off position.
Fig. 21 Body Controller 25-way Connector
3. Remove 25-way (Black) body controller connector.
4. Set wiper control to maximum delay position.
5. With ignition switch in On position, measure voltage between terminal 9 and body ground.
6. If voltage is present, remove wiper motor circuit fuse.
7. If no voltage is present, set wiper control switch to minimum delay position and measure voltage between terminal 9 and body ground. If no
voltage is present, check for an open circuit in the intermittent wipe wiring harness.
8. Remove wiper motor circuit fuse.
9. Using an ohmmeter, measure resistance between pins 9 and 22 of the black connector with wiper control first set to minimum delay and then
maximum delay.
10. If resistance at minimum delay is between 0-15 ohms and resistance at maximum delay is between 240,000-330,000 ohms, replace body
controller.
11. If resistance is not as specified, replace wiper control switch.
No "Extra" Wipes After Releasing Wash Control
In Delay Mode, Wipers Run Continually When Wash Is Operated But Do Not Provide Four Extra Wipes When Wash Control Is Released
1. Replace body controller.
