Hello everyone,

I am struggling with a problem on my 1990 accord where the dash lights don't go on when you turn on headlights. The combination turn switch on steering wheel activates and responds when switched. However I still don't have lights. Right on the dash there appears to be some sort of dial which I believe to be the dimmer switch. I am reading 12V on "BAT" pin of switch, when jumping BAT with O/P (output) nothing happens. Dash is still not illuminated even though there is power at the switch, and bypassing the switch does not illuminate the dash. Checked all fuses. No blown fuses..

Not all lights are out, the shifter sport mode is illuminated when activated HOWEVER. When turning switch at end of turn signal combination stick, these lights that are illuminated normally turn off when headlights are on. But the majority of the lights are off no matter what position the switch is in.

Does anyone have an idea what to test next? Where can I get some wiring diagrams?

Thanks again,
