I have a 94 4.3 4 door. Left turn will flash on panel and all signal lights on left flash on the outside like they are suppose to. Right side on front flash and on panel but rear left flashes also. Ordered new switch plugged it in. No change. Keeps burnin up my flasher. My hazards and hazard flasher have no problems. I recently put in new tail lights and had some bad bulbs and put in a 1 prong instead of a 2. Thought that was the problem. Replaced that bulb new switch no go. Clipped all wires in front for parking and front and side turn signals. Test light on them and i have 2 light blue wires hot for left blinkers. Turn on right blinkers and have 4 hot for them??? Dark blue and brown and Turn parking on have 1 hot on left 1 on right and same 4 blinker hots are also parking???? Wow help
