Wiring short- Fuse blowing for A/C and radio on same fuse

Unread post by bmbalive » Tue Jan 29, 2013 12:14 pm

I have a 1995 Toyota Avalon. Problem: a/c and radio are on the same fuse. Fuse keeps blowing. Tried to change switchboard for a/c controls out, as suggested. Still keeps blowing fuse. Trying to determine if it is the radio wiring, or the a/c wiring that has a short. I need to possibly re-run a new hot wire to one, or the other, or both. Not sure how to trace the short, or separate the two items on different fuses to help restore the radio or the A/c functions. Cannot use the heat, defrost, or a/c when this fuse i blown. Radio can stay inoperative,if necessary.

Why don't you try removing the radio and seeing if the fuse still pops.
