My Low beam head lights stoped working and only the high beams now work I have replaced the bulbs in both lights and they still do not work. I also checked the wiring from what I can see and nothing looks damaged. What could be causing just the two low beam headlights not to work if all other head lights and turnsignals are functioning properly

After looking at the wiring diagram for you truck, it looks like I would replace the headlight dimmer switch. The headlight relay and fuse send power to both the low and high beams, but the dimmer seperates which bulbs get the power when you select high or low beam.
