Where is the door sensor on a 2000 Chrysler sebring?

There isn't a single "door sensor" on a 2000 Chrysler Sebring. Instead, there are multiple door switches, one in each door (driver's, passenger's, and both rear doors). These switches are located inside the door itself, within the door panel.

To access them, you'll need to remove the interior door panel. This usually involves removing screws around the panel's edge and carefully popping the panel away from the door. The switch will likely be mounted on the door frame and connected to the door's wiring harness. The exact location of the switches can vary slightly depending on the specific door and model year. You'll see the switches after removing the panel. They are usually fairly obvious once the panel is off.
