Dash lights and sterio dont work, could that be a fuse and where is it located?

Check owners manual for your fuse box location. Remove and replace blown fuse. Normally located under driver side dash, passanger side dash or under your hood

Fuses under the dash.

This happend when you put a new sterio? Now your horn and tail lights dont work. Well some models require and extra harness to make the after market sterio work, check in to that. Or a fuse, make you where the wire is and trace it to see if it goes to the radio

have you recently installed a new radio ? I have knowen people to install radiosincorectly the dim wire behind the radio shows as a earth. however when you turn headlights on this becomes a positive. if you have wired this wire to your sterio this is whyyour dash lights & internal cab light etc keep blowing.. if your wondering why sterio still works is because its earthed through the aerial or mounting bolts.

Look for fuse panel under or either side of dash. Another location may be similar in engine bay.
Fuses probably labelled. Available at motor shops, garages etc.
If out of your experience then probably not expensive to ask auto electrician where to look. Many are cooperative and may tell over the phone or counter.

It helps to state what radio you have.....So did you find the fuse and its good?and getting power or just tried to find it? Try fuse 11 and 13 for the Nav. Fuse 8 and 9 inside and fuse 4 under hood for BOSE SYSTEM. Fuse 8, 9 under dash and 48 under hood for non BOSE

The ABS light on may be do to a loose connection on either the right or left ABS sensor which is located on the inside rocker panel on each wheel..The sterio may have speed control like mine.....The faster you go the sterio will increase in volume and lower when going slower cause of road noise or sun roof...Hope this helps you out.

if your dash lights don't work, it could be a fuse in the fuse panel located under the driverside dash board. be aware that if it is the fuse, you also wont have any tail lights either when you turn your lights on. Just brake lights.

Might be your ignition switch, or a fusable link from you battery. The switch makes more sense but i have no idea why it would screw up while you were driving. Usuall y that happens when you're starting it or shutting it off.

the connection to the light adjustment knob thats imbeded in your dash. the one that adjusts the intensity of your dash lights and such probably came loose or detached.
