just before the turn signal blew the tac. and the speedomoter bounced. the brake light blows as soon as i step on the pedal. both problems began @ same time to my knowledge. bulbs are good. its on a 94 chevy blazer full size. ive checked all other fuses and they are all good.

ive blown out the fuse box with the air hose and all under the dash. nothing else seems to be affected.

any ideas at all will be welcome. thanks guys. J
