Figure 2. Clip location on lower tailgate trim.
2.

With key on, check voltage at pin 1 and pin 4 of the rear wiper
motor connector (Figure 3 and Figure 4).
The voltage reading should show battery voltage (approximately
12.4V). If battery voltage is not found, continue diagnosis outside
this TSB.

4.

Compare the voltage readings between
pin 4 and pin 3 with the voltage readings
between pin 4 and pin 2 (Figure 6).
• If the voltage reading between pin 4
and pin 3 is more than .5V DC when
compared to pin 4 and pin 2, continue
to the next step.
• If the voltage readings are identical,
continue diagnosis outside of this
bulletin.

Figure 6. Compare voltage readings between pin 4 and pin 3 (A)
and between pin 4 and pin 2 (B).
Tip: Jumping pin 1 and pin 2 will actuate the motor. If the motor does not run with ground applied on pin
2, continue diagnosis outside of this bulletin.

8.

Use wiring harness repair kit VAS 1978B to
repair the splice, then reassemble the wiring
harness.
Tip: Utilize the proper connectors from the
repair kit as the heat shrink will seal out future
corrosion. The adhesive-lined inner layer will
keep moisture out.

9.

Reinstall the driver’s side kick panel.

10. Verify that the rear wiper is functioning correctly.
