To troubleshoot inoperative daytime running lights on a 1999 Grand Marquis, check the fuse related to the DRL system, inspect the DRL module for any signs of damage or corrosion, and test the DRL relay.

I suspect that your Control Unit itself has gone bad. That's what happened to me. A new control unit will cost between $400 and $500. I got one from a Junk Dealer for $100. It's been working for 3 years now. The control is real easy to change out. Hope this helps.
