Got an issue with my 2005 f150.
Basically if you turn the heater on level 3, it knocks out the radio. Turn headlights on and it will knock out the heater. Everything turns on the 4 way dash lights ( not actual exterior lights) and everything knocks out the brake pedal so I can't take it out of park, although brake lights work.
Kicker is, I hook up my scanner and truck works as designs. Unhook it and it goes tits up.
My friends dad is a master mechanic for Ford and he's even stumped, so I don't feel so bad.
He doesn't think it's the computer but something isn't letting the systems communicate but the scanner is forcing it to.
He's gonna do some research tomorrow and get back with me on how I should proceed
I hate electrical....
