2022-2025 Jeep/RAM/Dodge Washer Light On TSB S2323000002

Symptoms

Owners of 2022-2025 Jeep, RAM, and Dodge vehicles may experience a persistent warning light on their dashboard. The primary symptom is the "Washer Light On And Will Not Turn Off After Adding Washer Solvent." This indicates that the vehicle's system believes the washer fluid level is low, even after the reservoir has been topped off.

Diagnosis and Trigger Conditions

This issue typically arises in vehicles equipped with a continuity "prong" style washer level sensor. The problem occurs when rain repellent washer solvents are used. These specialized solvents can leave a silicone or wax residue on the sensor tips.

This residue acts as an insulating layer, preventing the sensor from accurately detecting the fluid level. Some rain repellent washer solvents may also be orange in color, though color alone is not a definitive indicator of the problem. The presence of this coating on the sensor pins is the root cause of the inaccurate reading, leading to the constant illumination of the washer fluid light.

Important Warnings

Stellantis notes that this document does not authorize warranty repairs. It serves as a record of past experiences and does not provide conclusions about what is definitively wrong with a specific vehicle. Technicians are responsible for determining the appropriate course of action.

Owners should also be aware that continued use of rain repellent washer solvents, even after cleaning the sensor, may reduce the long-term detection performance of the level sensor. It is recommended to switch to standard blue washer fluid after the repair.

Repair Procedure Summary

If a contaminated washer fluid level sensor is suspected, cleaning should be attempted before considering sensor replacement. The repair involves a few straightforward steps:

1. Drain and Inspect: The washer reservoir must first be drained. Following this, the fluid level sensor should be removed and inspected for any fluid coating buildup on its pins. Visual inspection will reveal if a residue is present on the sensor tips.
2. Clean the Sensor: If coating is found, the sensor pins need to be thoroughly cleaned. This can be done using soap and water or isopropyl alcohol (rubbing alcohol) to remove the silicone or wax residue.
3. Reinstall and Refill: After the sensor is cleaned and reinstalled, the reservoir should be refilled with standard blue washer fluid. If the Jeep Wrangler washer fluid light is now off, the issue is resolved. Vehicle owners should be informed about the cause of the problem and advised against using rain repellent washer solvents in the future.

Owner Action

If your 2022-2025 Jeep, RAM, or Dodge vehicle is displaying the "Washer Light On And Will Not Turn Off After Adding Washer Solvent" message, it is likely due to contamination of the washer fluid level sensor. You should consider having your vehicle inspected by a qualified technician.

Discuss the use of rain repellent washer solvents with your service provider. Switching to a standard blue washer fluid after the sensor is cleaned can help prevent the problem from recurring. This issue, as detailed in Stellantis TSB S2323000002 Rev A, is typically resolved by cleaning the existing sensor rather than replacing it.
