99 Blkazer Cluster Probs after shorting out

99 Blazer
 \\;
While i was installing a new radio, i grounded out a wire behind the radio and when i looked at my cluster, most of it was still working and everything was lighting up,but Now my fuel gauge doesnt work, all it says is LOW FUEL as does not show how much fuel is actually in the car....another issue is my temp gauge isnt working either, it lights up but doesnt move depending on the temp of the car, and my LAST prob is my gear display, the letters and numbers light up but cannot tell which gear is selected! i have been told it might be my PCM or BCM...? ANy ideas

check your fuses

i have already done that and all fuses are ok, undder the hood and also on the driver side dash
