** SOLUTION **
Cause
For vehicles model year 2018 to 2020, the windshield wipers may not function when the
intermittent setting is selected.This condition may result from wiper motor contact with
the motor slip ring, resulting in the current from the Light Control Module (LCM) to the
Wiper Motor to be too low.
Solution
A partial containment will be for the installation of a jumper harness that contains a
resistor to increase the current flow to the motor slip ring. Future containment will be a
new cab harness that will be a new cab harness that will have the resistor integrated.
NOTE: For trucks produced after 9 September 2019 (W1937), the aftermarket
harness will not be needed.
For applicable vehicles exhibiting the symptom described above:
1. Order Harness Jumper 23522546.
2. Install the jumper harness as shown in the picture below.
