I believe there isn't one, i have a '91 LeSabre and it doesnt have one. 87- 91 Lesabres are exactly the same cars, so it seems like you have a problem with your headlight staying on all the time. If that's the problem then i cant help you.

In the 2004 Buick Rainier, the daytime running light (DRL) module is typically located in the engine compartment, near the driver's side of the vehicle. It is often mounted on or near the fuse block. To access it, you may need to remove the cover of the fuse box. Always consult the vehicle's service manual for specific details and diagrams.
On my 1999 Buick Regal the DRL module is located on the outside foot well behind the parking brake pedal under the carpet. My DRL has gone bad and is making the car quit.
Where can I locate the "Lamp Control Module" on a 1994 Buick Park Avenue
It's on the passenger side, above the kick plate.
I think under the hood covered with shroud on the firewall.
Electronic spark timing. May need module. Need more info.
Check battery and cables
On a1996 Buick Le-sabra it is on the Driver side under hood right below brake fluid reservoir.
It is the headlight drive module. It is used for daytime running lights and low beam operation. It works in conjunction with the light sensor on top of your dash that senses how much light is available, and tells your lights to come on or your drl. You have to have lights on automatic.
