ok. i hae a 98 mustang gt and my rpm,speedo,oil pressure,ect dont work when i turn the lights on also the ac lights dont work.

on my instrumental cluster the check engine light and the abs and everything works just not the gauges. also my radio and everything still lights up.

i just checked all my fuses and the instrumental illumination fuse was broke and cracked but i replaced it and still nothing. any ideas. could my cluster have gone out or something help..

i also installed a new radio and it worked before i installed the radio so i think it has something to do with the new radio

 

I would pull that radio and check the wiring behind it just to make sure.

 

Sounds like u just answered your own question
