Your non-working instrument panel lights, tailights, and parking lights have ONE thing in common, they are controlled by the same switch which controls the headlights. The working brake lights do not even figure in the analysis as they are on a totally different circuit from ALL of those other lights. The headlights, tailights, and parking lights ARE on the same circuit, AND are controlled by different sets of contact points inside of the "headlight" switch. Although there may be more, I can only think of three causes for the symptoms you describe. 1. A loose, or disconnected wire or harness involving the circuit for those lights. 2. Corroded contact points within a connector in that circuit. 3. A defect [probably overheated, "cooked"] in the contact points for those lights INSIDE the headlight switch. I suspect that 3 is the cause, but due to cost of a headlight switch, and the difficulty in changing it, it would be a good idea to check out 1 and 2 first, as those problems do not generally require the replacement of any parts, only disassembly, cleaning, and reassembly. I suggest you eleminate numbers 1 and 2 first, then if that does not correct the problem, consider replacing the headlight switch.

The headlamp switch controls the power to the dimmer switch and then on to the headlights.The headlamp switch controls the power to the dimmer switch and then on to the headlights.

it is below the headlight/dimmer knob, on the back of the dashboard. it is a pain to get to, requiring you to pretty much tear the dashboard out to get behind it

Probably because the dimmer switch is turned off. Turn the dimmer switch up and see if the dashlights and radio illumination lamps come on.

Your headlights may not dim because you don't have dimmer lights. Dimmer lights can blow and leave you with just the high beams.

It is on the side of the steering wheel and is used for turning your headlights on and off it is also used to control your high beams and low beans

Check fuse that controls parking/tailights check dimmer rheostat check headlight switch go to the local ford dealer ship and buy new dash lights

If the dashboard dimmer switch works with the other dash lights, the fault is in the radio unit itself.
