On my uncle's car, a 99 Taurus SE 3.0DOHC, the headlights don't work at all. His side markers and accessory lights do work. He doesn't know if his car has DRLs or not. Everything I've read leads me to believe its the DRL control module. I've checked all the fuses, my uncle replaced control switch that's in the dashboard. Using a volt meter I tested the connections where the headlight bulb plugs into wiring harness, no power there. If its not the DRL, the MFS is the only other thing I can think of. Any ideas, or ideas on how to determine which of the two are the problem?
