Where is the parking lamp relay located on a 1997 Buick LeSabre and which it?

The 1997 Buick LeSabre's parking lamp relay isn't a single, easily identifiable relay like some cars. The parking lights are controlled through the Body Control Module (BCM) and aren't usually routed through a separate, easily accessible relay. The BCM itself handles the switching.

Therefore, there isn't a specific "parking lamp relay" to find. Any issues with the parking lights will likely point to a problem with the BCM, wiring harness, or a switch within the system (like the headlight switch). Troubleshooting this usually requires a multimeter and a wiring diagram specific to your 1997 LeSabre.
