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.
Turn on headlights/parking lights and adjust dimmer control
Replace bulbs? Check dimmer rheostat for open circuit Check fuse for parking/tailights
Check to see if the parking/tailights are working Could be a bad fuse, or switch Could be an open in the dimmer rheostat
Check to see if parking/tailights work - should be same circuit - check fuses Could be a bad dimmer rheostat Could be a bad light switch
Check fuse for parking/tailights Check the rheostat dimmer switch
Check fuse for parking/tailights Could be a bad headlight switch Could be an open in the dimmer rheostat
If parking and tailights are not working check the fuse If they are working: Bulbs burned out? Dimmer rheostat has an open (switch)
Check to see if parking and tailights are working - should be the same circuit - check fuses May be the dimmer rheostat needs replacement
Do parking/tailights work? Should be the same fuse Could be an open in the dimmer rheostat Could be a bad switch
Check fuse for parking/tailights Could be bad dimmer rheostat Could be bad headlight switch
Check fuse for parking/tailights Check for an open circuit in the dimmer rheostat Could be a bad headlight switch Burned out bulbs?
Check the dimmer control Check to see if parking /tailights are working - if not check fuse May be defective switch
could be bad wiring
Probably because the dimmer switch is turned off. Turn the dimmer switch up and see if the dashlights and radio illumination lamps come on.
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
On my 2000 Forester, the dashboard illumination dimmer control is on the turn signal stalk. --Ken

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.
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
the dimmer switch is going out if you are experencing that.
If the dashboard dimmer switch works with the other dash lights, the fault is in the radio unit itself.
Check to see if parking/tailights work (same fuse) Could be an open circuit in rheostat dimmer control Could be a bad headlight switch Could be bulbs have burned out
Change your dimmer switch, it went out.the dimmer switch will allow your lights to work but cause problems with your high beam,also can cause your parking lights to short out. Change it asap
DIMMER SWITCH FAILURE.
