2025-2026 Jeep Compass, Renegade AC Not Cooling TSB

Jeep has released Technical Service Bulletin (TSB) 24-003-25, also identified as Rapid Service Update (RSU) 25-173, to address concerns regarding the air conditioning system in certain 2025-2026 Jeep Compass and Renegade models. This bulletin specifically targets vehicles that may experience inadequate cabin cooling due to a refrigerant leak.

This TSB applies to 2025-2026 Jeep Renegade (B1), 2025-2026 Jeep Compass (M1), and 2025-2026 Jeep Commander (H1) vehicles. It covers units built on or after August 19, 2024 (MDH 0819XX) and on or before June 18, 2025 (MDH 0618XX). The bulletin is applicable to both North and South American markets.

Symptoms

Owners of affected vehicles may notice that their air conditioning system provides "Air conditioning provides insufficient cabin cooling." This means the vehicle's interior does not cool down as expected, even when the A/C is set to its coldest settings.

Cause

The primary cause identified for the insufficient cabin cooling is an "air conditioning refrigerant leak." This leak originates from the evaporator piping, specifically at its intermediate connection point within the A/C system.

Diagnosis

To determine if a vehicle is affected by TSB 24-003-25, technicians should first check the customer's VIN against the VIP system or the RSU VIN list. If the VIN is listed, the repair procedure should be performed. However, if a vehicle is not on the VIN list but exhibits the symptom of "Air conditioning provides insufficient cabin cooling," the repair procedure should still be followed to diagnose and potentially resolve the issue.

Repair Procedure Summary

The repair procedure outlined in TSB 24-003-25 involves an inspection and potential replacement of the evaporator piping. The steps are as follows:

1. Preparation: Start the vehicle and activate the air conditioning system. Set the A/C to minimum temperature and maximum fan speed. Keep the hood open and allow the engine to run for at least 20 minutes to ensure the system is fully engaged.
2. System Shut Down: After the 20-minute run time, turn the ignition to OFF.
3. Locate Component: Identify the evaporator piping at its intermediate connection point. Technicians will refer to Figure 1 in the TSB for visual guidance on locating this component.
4. Inspect for Leakage: Carefully inspect the evaporator piping to intermediate connection for any evidence of ice formation or excessive condensation, as shown in Figure 2 of the bulletin. These visual cues indicate a potential refrigerant leak.
5. Decision Point: If ice or excessive condensation is observed, the technician should proceed to Step 6 for replacement. If no such evidence is found, the bulletin is considered completed for inspection purposes, and Labor Operation (LOP) 24-45-21-90 should be used to close the active RSU.
6. Replacement (If Needed): If a leak is confirmed, the evaporator pipe must be replaced. Detailed service procedures for this replacement are available in DealerCONNECT/Service Library under Service Info > 5040A88 - Tubulação Do Evaporador À Conexão Intermediária - R.R..
