I believe that would be Daytime Running Lights ( Canada in 1991 )
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.
If your car doesn't have DRL's the switch is faulty or the wiring has a short in it to a power source..
DRL are your Daytime Running Lights
Go to your local library and look in the "Mitchells" books, or depending on where you live, if you have a library card you may be able to access online repair data for your vehicle. We have the ability to do so where I live. This is a wondeful tool.
DRL stands for Daytime Running Lamps.
The DRL Module is located at the LH Rocker Panel left of the brake, under and just below the dash. The DRL Module and the DRL Relay are side-by-side.
DRL usually stands for Daytime Running Lights
DRL = daytime running lights
DRL cannot invert signals.
