Excessive Delay or Inadequate Variation In Delay

Fig. 21 Body Controller 25-way Connector:

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.
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, proceed to step 9.
7. If no voltage is present, set wiper control switch to minimum delay position and measure voltage between terminal 9 and body ground.
8. If no voltage is present, check for an open circuit in the intermittent wipe wiring harness.
9. Remove wiper motor circuit fuse.
10. 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.
11. If resistance at minimum delay is between 0 and 15 ohms and resistance at maximum delay is between 240,000 and 330,000 ohms, replace body controller.
12. If resistance is not as specified in step 11, replace wiper control switch.
