The blinkers are not working?

When I turn on the headlights, all my dashboard lights go off. The turn signals turn on inside but do not flash. The heater will not come on, just get a buzzing sound. The fuse box loses power to half of it when lights r off, but it starts and runs fine. Door locks will not work, neither will the power seats. But the windows do. Driver side window will go down by itself, but will go back up. Friend who is a ford mechanic said possibly body control module. Any ideas? Thanks much

I have a 1997 F150 pickup and the turn signals only work when there's no headlights on and the heat is off. If the lights are on there's no turn signals. If the lights are off and I put the heat on there's a buzzing noise coming from the flasher under the drivers dash. When headlights are on there are two green arrows on dash lit up. High beam shows up but the high beam is not on. When headlights are off dash lights come on. When lights on hazards don't work. Lights of and heat off Hazards work. Never seen this before please help.

Truck doesn't have Day Running Lights. What would high beam on headlights have to do with blinkers and heat. The truck has no heat coming out of vents. If you turn on heat and turn it from low to high there's no heat and there's a buzzing noise coming from the flasher under dash. If lights are on the blinkers will not work the heat still doesn't work but there's no buzzing noise from heat when headlights are on. Not sure whats going on.

What wires do you check in steering column, for signal light relay
