When a vehicle's sunroof works intermittently, what could be causing the issue according to the technicians?

• A. Poor wiring connection
• B. Binding panel in the rails
• C. Both poor wiring connection and binding panel
• D. Defective motor

Answer: (C)

When a vehicle's sunroof operates intermittently, it is often indicative of multiple potential issues that can affect its performance. A poor wiring connection can lead to inconsistent electrical signals being sent to the sunroof motor, which may cause the sunroof to function sporadically. This can result from corrosion, loose connections, or damaged wiring that disrupts the current flow. In addition to wiring issues, a binding panel in the rails can also be a contributing factor. If the sunroof panel does not move smoothly due to obstructions, dirt buildup, or misalignment in the rails, it can hinder the proper operation of the sunroof. As the mechanism struggles to move, it may stop working altogether or work only intermittently. Considering both of these possibilities, having a combination of poor wiring connections and binding in the panel rails could very well explain the intermittent operation of the sunroof. Therefore, recognizing that multiple issues could be at play enhances the diagnostic approach, allowing for a thorough inspection and resolution of the problem.
