Have a 01 f150 4.6 crew cab with key out and door closed I have the check engine light on oil light and abs light stay on not bright but bright enough to see and I get power to window switches and switch for my pedals to move up and down it will drain the battery. I replace gem module relays ignition switch interlock solenoid headlight switch everything is stock on truck need help please

 

have you noticed the drivers floor being wet after a rain ? Is it possible the windshield leaks ? There have been some occurances of random electrical problems due to water leaks.

 

 

All power for the dash comes through the ignition switch.
Is it releasing?
Are leads in the harness to it crossed etc.?
The key tumbler is only the lock, not the switch.
The tumbler operates a rod to the ignition switch down the column.
Check all this out.
