In Canada 800.00 dealer repair, we have 37 PPV 12-14 tahoes, every vehicle needs door panel replaced. This $20 fix works, we have added a 6 inch 1/4 bold along the inside of the Handel, melted into the plastic with soldering gun, filled with construction adhesive, hard as a rock, strong winds and meaty hands here in Saskatchewan.I saw a really thorough repair on YouTube. Someone removed the door panel and fabricated aluminum and steel components that drill into the small amount of sheet metal parts in the door. It's like the most robust version of the popsickle stick mod.
My 2500 has both the driver and passenger doors needing this mod. Aaargh! The actual replacement part could be like $5 but instead you need an entire $400 door panel?! No thank you.
