From what i read, the main issue of a failed daytime running lamp module is when the daytime running lamps that do not come on. Since the module is what controls the lamps and feeds them power, if the lights fail, the daytime running lamps will be left without power and will not function as a result.
One site says...
A dedicated daytime running light module is used in some vehicles to automatically control low beam headlight operation. The module receives input from various sensors and switches including the ambient light sensor, ignition switch, headlamp switch and parking brake switch. It then uses this information to adjust the low beam headlights as needed. A defective daytime running light module can result in low beam headlights that stay suck on, operative erratically or don’t work at all
Anyone else ever deal with this issue on a 3.6....????
Thanks
