Can you replace a drivers side window regulator with the one from the back seat drivers side passanger door?

In most cases, you can use a rear driver's side window regulator to replace a front driver's side regulator, but compatibility depends on the vehicle make and model. Window regulators are often designed specifically for each door and may vary in size, mounting points, and cable length. It's best to consult the vehicle's service manual or a professional to ensure a proper fit and function. Always prioritize safety and proper installation when replacing automotive parts.
