Detailed Description

Dorman 601-380 is engineered for Cadillac vehicles where the factory door handle microswitch fails from wear or moisture intrusion.

What It Helps Fix

• Non-functioning exterior door handle switch on the front left door
• Passive entry problems caused by a failed microswitch connection

• Need to replace only the damaged switch connection instead of the full handle assembly

Installation Notes and Tips

Install on the front left door handle location only for the listed Cadillac applications. Verify connector style, terminal count, and harness routing before installation. Because this repair uses a plug-and-play approach, it is important to match the original electrical layout and secure the harness away from moving door components and moisture exposure.
