the fuse to the bottom left hand side under the dash keeps blowing upon moving the key to the 3rd position right b4 hitting the starter. its the one going to the turn signals and backup lights. i cant find the short. what wires should i be checking what bulbs? what possibly could be causing it? ive got a multimeter just need to know what wires to check for continuancy. i tried all day yesterday and blew about 20 fuses, doesnt blow until u engage the ignition switch to the position right b4 u hit the starter. ANY HELP APPRECIATED cuz im stumped. when it blows it cuts out the tachometer side of the center gauges, the heat sensor and tach, but not the gas gauge and rpm gauge. i need turn signals.... TIA FOR ANY INPUT
