Headlights wont turn off and on the dash it shows high beams when the swith for lights are off but turn the switch on the indicater turns off. I had to disconnect the battery for the headlights to turn off. The Ford Dealership said the car did have DRL. However, I remember seeing them on during the day. I think the car does have DRL, they are just not working right now! Thank you,

Thank you...I visited three Ford.Mercury dealerships and they all say that my Sable does not have DRL, therefore there is not a DRL module for my vehicle. As I explained to the dealers, my owners's manual states the car has it. There is a dedicated fuse 15-Amp) in the distribution box under the hood. I removed the fuse, and the light went out. By removing the fuse, it only effected the highbeam indicator light; That's no big deal, I can tell when the highbeams are on anyway! After I complained, one dealership is now saying that I may have automatic lights that shine at a reduced rate when the car is moving through dark areas, like tunnels. The other dealerships disagree with that statement. Again, thank you for your time. John Morgan, USMC
