The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some customers may complain that the rear wiper and/or the front rain sense wipers (if equipped) turn off when the vehicle is shifted to neutral.
This is called Car Wash Mode
The intent of the car wash mode is to disable the wiper(s) while in a car wash to avoid the potential excessive mechanical forces associated with wiping while in
that environment.
For the rear wiper and/or the front rain sense wipers to be disabled, the vehicle must be below 5 kph (3 mph) and the transmission in neutral.
Once the wipers have been inhibited, the normal wiper operation will not return until either of the following has been met.
1.
The transmission has been shifted out of neutral for 10 seconds.
2.
The vehicle speed is greater than 5 kph (3 mph).
Recommendation/Instructions
Do NOT replace any parts for this concern. This is the normal operating characteristic of this vehicle.
