What is your question?
If I turn on my lights or air my turn signals light up along with the brights symbol on my dash board and I lose the ability to use them sometimes even with out turning anything on also shifter locks if it is a problem when I first started the vehicle
What makes this problem better or worse?
When I turn on lights or air
How long has your 2004 Ford F-150 had this problem?
Few weeks

This could be wiring, a bad ignition switch, shifter interlock, combo switch, etc. Too many variables to diagnose online. It's best to have it looked at by a shop. Use this link to find a good one near you. https://repairpal.com/repair-shops Alex
