Chevrolet Repair: 1995 S-10, fuse holders, fuse panel

Question
Just bought it and was told a/c didn't work, so when I was heading home with it I turned on the knob to vent and the speedometer quit working and the brake light came on, I also tried it on heat setting and a/c...same problem

Answer
Hi Terry ... you must have a short in the heater control circut...check wiring under dash and see if any wires are burnt and melted together....also check at the fuse panel for corrosion on fuse holders...as well as wiring for A/C under the hood... hope this helps
