Sundance L4-135 2.2L SOHC VIN D TBI (1992)
Wiper Control Module: Testing and Inspection
Excessive Delay of More Than 30 Seconds or Inadequate Delay
1. Variations in delay should be as follows:
a. Minimum delay control to extreme counterclockwise position before first detent of 1/2 to 2 seconds.
b. Maximum delay control to extreme clockwise position before OFF detent of 15 to 25 seconds.
2. If there is excessive delay or no variations in delay, remove the wiper motor wiring harness while the motor is parked in the OFF position.
3. Remove 25-way blue connector from the body controller.
4. Set wiper control switch to maximum DELAY position.
5. With ignition switch in ON position, measure voltage between pin 9 of black connector and a good ground.
a. If voltmeter reads 0, proceed to step 6.
b. If voltmeter reads 10 to 15 volts, proceed to step 7.
6. Set wiper control switch to minimum DELAY position and measure voltage between pin 9 of blue connector and a good ground. If voltmeter reads
0, check for an open circuit in the intermittent wipe wiring harness.
7. Remove wiper motor circuit fuse.
8. Using an ohmmeter, measure the resistance between pins 9 and 22 of the body controller 25-way black connector. Set the wiper control switch first
to minimum DELAY and then maximum DELAY.
a. If resistance reading at minimum DELAY setting is between 0 and 15 ohms, and at maximum DELAY setting the resistance is between
240,000 and 400,000 ohms, replace the body controller.
b. If the resistance values above are not obtained, replace the wiper control switch.
