Does anyone have any ideas on what I should look at next? I have an 02 century I installed an aftermarket stereo awhile back, the other night I heard a pop and the stereo gauge cluster and obd port isnt working now. The cluster still illuminates but the gauges dont function. I have checked the fuse box under the hood and the one on the right side of the dash but couldnt find any popped fuses. Im just noot sure where to look next any ideas on what to check are greatly appreciated.

Hi,

There is a 15-amp fuse in the fuse box at the right-side end of the instrument panel. I need you to check that fuse.

If you look below, I attached a pic of the wiring schematic for that fuse, and it powers everything you lost. Pic 2 shows the location of the fuse I'm referring to.

When you check the fuse, first make sure the fuse itself is good. If it is, you need to confirm there is power to and from it. Here is a link you may find helpful:

Let me know what you find or if you have other questions.

Take care,

Joe
