To repair the driver's heated seat on a 2000 Chevy Impala, follow these general steps:
Check the fuse: Locate the fuse box and inspect the fuse related to the heated seats. Replace it if blown.
Inspect the seat switch: Sometimes the switch itself goes bad. Use a multimeter to test for continuity.
Test the wiring: Look under the seat for loose, disconnected, or damaged wires. Repair or replace as needed.
Check the heating element: The most common issue is a broken heating element inside the seat. You’ll need to remove the seat cover, inspect the element, and replace it if there's a visible break or it's not conducting power.
Replace parts if needed: Heating elements and switches are available online or at auto parts stores.

What year impala? For 2000-2004, the actual ground wire is Pin F on the heated seat relay driver (control module) located underneath the seat. That ground wire comes from the main harness coming from underneath the carpet to the seat, and ultimately ties into a body bolt below the drivers opening, rear of the left A pillar.
