Welcome to Just Answer and thank you for asking your question. I look forward to helping you fix your vehicle.
I will try my best to help you and in order to do that, I need you to describe the issue in as much detail because I only know as much about your vehicle as you have told me in your post, so my answer will be based on what you have posted. Please include all the small details that may seem insignificant such as warning light or noises.
My goal is your satisfaction and I ask that you not accept unless you are satisfied, but if you are satisfied, please accept so I can receive credit for my work and time. Positive Feedback is greatly appreciated and bonuses are always welcomed.
Please feel free to reply as needed.
This CHMSL is a tube so it is likely faulty. Below are replacement instructions.
Notice: Do NOT raise the liftgate while the liftgate glass is open. This can result in damage to the high-mounted stoplamp, the liftgate hinges, or the liftgate glass.
This is a dealer only item.
