2025-2026 Jeep Compass Passenger Window Not Operating

Owners of 2025-2026 Jeep Compass (MP) vehicles may encounter an issue where the passenger power window fails to operate from the driver's master window switch. This condition, detailed in Technical Service Bulletin S260800003, typically occurs without any diagnostic trouble codes (DTCs) being present.

This bulletin provides a diagnostic procedure for technicians to follow when addressing the Jeep Compass passenger window malfunction, focusing on the master window switch and its connections.

Symptoms

The primary symptom reported by owners is that the passenger power window cannot be lowered or raised using the driver's master window switch. This specific fault, labeled as "Passenger Power Window Does Not Operate From the Drivers Master Window Switch," indicates a problem with the control signal from the driver's side.

Diagnosis and Trigger Conditions

When diagnosing this issue, technicians should first disconnect the master switch. Following this, a thorough inspection of the wiring harness is required to check for any signs of circuit push-outs or terminal spread conditions. These physical defects in the connector can disrupt electrical signals.

To ensure proper connection, technicians are instructed to secure the connector using the "PUSH-PULL-PUSH" method. After re-securing, the operation of the switch should be tested. If the issue persists, further testing of the internal switch resistance values is necessary before considering a replacement of the master window switch.

Repair Procedure Summary

Before replacing the master window switch, technicians must perform specific resistance tests. These tests measure the internal resistance between designated pins on the switch when different buttons are activated. The results of these tests should be documented and included with any claim if the switch is ultimately replaced. The expected resistance values are as follows:

• Driver button UP: Between pins 1 and 9, resistance should be 649 +/- 7 Ohms.
• Driver button DOWN: Between pins 1 and 9, resistance should be 2519 +/- 25 Ohms.
• Passenger button UP: Between pins 1 and 14, resistance should be 649 +/- 7 Ohms.
• Passenger button DOWN: Between pins 1 and 14, resistance should be 2519 +/- 25 Ohms.
• Rear Right button UP: Between pins 1 and 4, resistance should be 649 +/- 7 Ohms.
• Rear Right button DOWN: Between pins 1 and 4, resistance should be 2519 +/- 25 Ohms.
• Rear Left button UP: Between pins 1 and 7, resistance should be 649 +/- 7 Ohms.
• Rear Left button DOWN: Between pins 1 and 7, resistance should be 2519 +/- 25 Ohms.
• Door lock button: Between pins 1 and 8, resistance should be 610 +/- 7 Ohms.
• Door unlock button: Between pins 1 and 8, resistance should be 610 +/- 7 Ohms.

These precise resistance measurements help determine if the master window switch itself is faulty or if the problem lies elsewhere in the electrical system affecting the Jeep Compass passenger window operation.
