If you're referring to instrument lighting take a look at the stem you press to zero/toggle the trip meters. Turning that stem left will dim the instrument lighting, to the right brightens. That's the procedure for the Gen II (04 and later) Solara. The Gen I may be different. The information is in your owner's manual.

Yes, the button is located below the dimmer slider for the interior lights.
inside car (driver side door). Basically behind the interior light dimmer.
Have you tried the dimmer switch? It is usually located next to the headlights switch. On pull out headlight switches, rotating the switch itself clockwise or counter clockwise is the dimmer switch and interior light switch.
Have you checked the guage panel dimmer wheel switch ( just to the right of your headlight switch on your dash ) to see if it has been rotated all the way down ? The dimmer wheel is used to adjust the backlighting brightness of your guages and also , if it is rotated all the way up , it turns on all your interior courtesy lights - Helpfull
I don't know if this will help you or not, but on my '96, the interior light dimmer is a rotary thumbwheel located low on the dash where the driver's left hand can operate it. When it's rotated all the way to the right, the interior light comes on.
Yes, the dash light dimmer switch is located next to the headlght switch. You rotate it one way and the lights dim out, rotate it the other way and they get brighter, keep rotating it that direction and the interior light comes on.
Just a guess , has your guage lighting dimmer wheel switch been rotated all the way down ( or to one side ) ? I believe that will turn off all the interior lights It is located to the right of your headlight switch
The 1993 BMW 325 dimmer switch is located on the lower left-hand side of the dashboard. The dimmer switch is a dial switch.
I have a 2004 XG350L doing the same thing. Turns out it was a bad interior dimmer switch.

The panel dimmer control is to the right of the headlamp control. If you roll the panel dimmer control up past detente (the catch), it is in the full up position and all of the interior lights will remain on. If you roll the panel dimmer control down past detente, the interior lights will turn off (unless they are individually turned on in which case the panel dimmer switch is overridden). I would also suggest the question could be related to interior lights that keep coming on due to a stuck door ajar switch. See "Related Questions" below for more about that.
If you want to turn on the interior lights rotate your gauge panel dimmer switch wheel all the way up ( it's located on your dash just to the right of your headlight switch )
