Installation Notes and Tips

This assembly uses a bolt-on attachment type and is intended for the rear left door on compatible Cadillac DTS models. Mounting hardware is not included, and installation instructions are not included. Verify connector style, door position, and vehicle equipment before installation. Because the regulator and motor are supplied as an assembly, replacement is typically performed as a complete unit rather than servicing individual internal components.

Quality Assurance

Dorman manufactures this replacement assembly to match the original part’s fit and operating characteristics on specific vehicle applications. It is extensively tested during development to help ensure consistent performance in the intended Cadillac DTS fitment.
