I installed a couple things last night:
a dual usb outlet into the AUX input spot (that aux input is now permanently behind the dash, with a permanent cable running to the top of my HU that plugs into my iPhone/pad/pod)
and a different power outlet in the stock cig. lighter (i hated the silver old one, and the lack of a plug for the open hole)
well, after it was all back together, no fuses blown, the bulb filaments look fine, the AC panel has no lighting, and my hazard button light is off.
the AC button and the recirculate button do light up when engaged, (only the marker light, not the icon)
No idea what to do now...
Last night the two left dials did work, but the right one did not, NOW, all three are off.
