Where is the dash light fuse in a 1986 z28 Chevy Camaro?

There isn't a single "dash light fuse" in a 1986 Camaro Z28. The dash lights are powered through a circuit that likely uses multiple fuses, and potentially the dimmer switch itself. The relevant fuses are likely to be found in the underhood fuse box and/or the interior fuse panel (usually located under the dash).

To find the correct fuse(s), you'll need to consult your owner's manual. The owner's manual will have a fuse box diagram showing which fuse controls what circuits. Look for fuses labeled as "instrument panel illumination," "gauges," or something similar. If you don't have the owner's manual, you can often find a downloadable version online by searching for "1986 Camaro Z28 owner's manual PDF."

Without the manual, troubleshooting will be much more difficult. Testing each fuse with a multimeter is the safest way to proceed. Simply checking visually may not identify a blown fuse if it's not completely broken.
