2019-2025 Jeep/RAM Headlamp Condensation TSB 23-008-25

Stellantis has released Technical Service Bulletin (TSB) 23-008-25, dated February 14, 2025, to address customer reports of headlamp condensation. This bulletin, which supersedes TSB 23-004-24 REV. A, issued on August 06, 2024, provides guidance on how to evaluate and resolve light condensation within exterior headlamp assemblies for various 2019-2025 Jeep and RAM models. This TSB is especially relevant for owners experiencing Jeep Wrangler headlamp condensation.

Symptoms of Headlamp Condensation

Owners may observe a light layer of condensation on the inside of their vehicle's exterior headlamp lenses. This can happen after the headlamps have been on and then rapidly cooled, such as during rain or a car wash. Condensation can also appear under specific atmospheric conditions, like a warm, humid day followed by a clear, cool night, especially if the vehicle has been parked outside overnight.

Diagnosis and Evaluation

To determine if the condensation is normal or indicates a problem, a specific evaluation procedure should be followed:

1. Ensure all water is dry from the outside surface of the headlamp lens.
2. Operate all outside lamps for 20 minutes by starting the vehicle engine, turning on the headlamps, and activating the hazard warning flashers.

If the condensation begins to clear from the headlamp lens after 20 minutes of operation, it indicates that the lamp sealing has not been breached. In this scenario, the headlamp does NOT need to be replaced.

Important Warnings for Owners

It's crucial for owners to understand the distinction between normal condensation and a sealing issue. If the condensation clears after the prescribed 20-minute operation, the headlamp is functioning as designed, and replacement is unnecessary. However, a headlamp that exhibits internal moisture permanently, or has large amounts of water droplets on most internal surfaces, should be replaced as this indicates a sealing problem.

Common Causes for Persistent Condensation

If headlamp condensation does not clear, or if significant moisture is present, it often points to a sealing issue. The TSB identifies two primary causes for heavy, non-normal condensation or fogging:

• Damage: Breakage on the headlamp housing, such as cracks or holes, can allow moisture to enter. This type of issue would be recorded with the failure code "11/BROKEN OR CRACKED."
• Missing or Damaged Sealing Components: Missing vent caps, access caps, or bulb sockets, or incorrectly installed components, can compromise the headlamp's seal. This condition would be recorded with the failure code "1C / CONNECTOR LOOSE NOT ATTACHED."

Repair Procedure Summary

For light condensation that clears after the evaluation procedure, no repair is needed, as this is considered normal operation. Turning the headlamps ON will usually accelerate the clearing process. If the evaluation reveals persistent moisture or significant water ingress, indicating a sealing problem, the headlamp assembly will require replacement. Technicians are directed to refer to detailed service procedures in DealerCONNECT/Service Library under "Service Info>08 - Electrical / 8L - Lamps and Lighting / Lamps/Lighting - Exterior / Unit, Front Lamp / Removal and Installation" for replacement instructions. This TSB, 23-008-25, is for informational purposes regarding the proper diagnosis and resolution of Jeep Wrangler headlamp condensation.

Owner Action

If you observe Jeep Wrangler headlamp condensation or similar issues in your 2019-2025 Jeep or RAM vehicle's headlamps, first try the recommended clearing procedure by operating your headlamps for 20 minutes. If the condensation does not clear, or if you see significant water droplets, it's advisable to contact your authorized Stellantis dealer for diagnosis. They can perform the evaluation and determine if a headlamp replacement is necessary based on the guidelines in TSB 23-008-25.
