Default small light fuse, keyless fuse and hazard switch fuse keeps blowing

happened roughly a week ago
I noticed that my little 10a small light fuse was blown underneath the footwell (inst cluster light, AC Climate control dash illumination, headlight, tail light parking light). The fuse blows up every time i replace it as soon as i turn on the headlight/parking light switch..

On top of this problem, my keyless entry fuse started blowing as well along with my hazard light fuse underneath the hood.
I did some research on this and might have thought my aftermarket radio could be the culprit. I checked the radio by unplugging the whole unit and replacing the fuse but it still keeps blowing.

Anything else i should start checking? perhaps a relay underneath the hood? please help

Do the hazard and keyless fuses blow as soon as you put a new one in, or is it random?

As for the small light fuse, you are shorted to ground somewhere. That fuse feeds the bulbs that light the heater control panel, cruise switch, rear defrost switch, hazard switch, convertible top switch, and it feeds the radio for its dimming purposes. I would start by pulling the center console up and checking the wiring to the fore-mentioned bulbs.

And to tie everything together, the hazard switch uses the small light circuit for its bulb, and the hazard circuit for obvious reasons, and the keyless entry module is connected to the small bulb circuit to flash the lights during unlock and such. All three circuits are connected via that switch.

Try unplugging the hazard switch and seeing if the small light fuse blows with the headlight switch on. And if you have a multimeter handy, use it to check for a short to ground within the small bulb circuit.

figured out the problem.
The Left headlight wires were starting to expose behind the headlights, wrapped them up and secured them nicely and everything works good again

FIXED. Disconnected my aftermarket radio and then tried a new fuse -> stopped blowing when I turn on parking lights. Found a couple of exposed wires in the radio harness so I taped them all up. PROBLEM SOLVED!

Try Posi Lock connectors. Small and bulletproof.

Cosmo, I never seen those before. Have you tried using them? Are they okay in gas and oil enviroments?

Thanks!
