Cause of the Issue

Important Warnings for Owners and Technicians

This TSB emphasizes critical steps and warnings to ensure proper resolution and prevent unnecessary part replacements:

• First Action for Customer Symptom: The initial and most crucial step for any customer experiencing an inoperable UGDO or having operational questions is to contact HomeLink® Customer Care first.
• Do Not Replace Parts Prematurely: It is explicitly stated: "Do not replace the sunvisor/UGDO without following the GPOP first." This warning prevents technicians from replacing the sunvisor, which typically houses the UGDO, before attempting programming assistance and consulting further diagnostic procedures.

Recommended Actions and Next Steps

If you are experiencing issues with your Universal Garage Door Opener (UGDO) or have questions about its HomeLink® programming, follow these recommended steps:

1. Contact HomeLink® Customer Care: The first action for any customer symptom related to the UGDO is to call HomeLink® Customer Care directly at 1-800-355-3515. They can provide assistance with programming the UGDO.
2. Consult Your Owner's Manual: Dealers are advised to suggest that customers consult their vehicle's Owner's Manual for additional guidance on UGDO operation and programming.
3. Further Dealer Assistance (If Needed): If the problem persists even after contacting HomeLink® and consulting the Owner's Manual, your dealer should then refer to the General Procedures (GPOP) document GPOP 9100591 for further diagnostic and repair steps. This ensures that all programming and customer support avenues are exhausted before considering more involved repairs. This process is crucial if your 2026 Jeep Wrangler UGDO inoperable condition continues.
