Just bought 1999 ford mustang gt. They had some ugly tail lights and it had gotten some front end damage so the car has all new headlight and taillight assemblies. The passenger side taillight was filled with water, so the reverse light and the light with only 2 wires going to it were rusted. I replaced the plug for the bulb, new bulbs all around, and the issue i have is that the blinkers dont work like they should. When in daylight and i have the headlights or running lights off, the blinkers work perfect. All lights work perfect. But when i turn the running lights on, the driver side blinker dash lights stays solid, but will blink when i turn the blinker on. The blinkers in the front and back work but they blink fast. Right side works perfect. If i turn hazards on, the rear blinkers work right, but the front blinkers alternate so it blinks left, right, left, right instead of at the same time. I turn off the running lights and its back to normal. Any clue what may be going on? I have replaced fuses as the water in the taillight blew the fuse. All fuses are good, i havent changed the flasher modules in the dash, or relays. How should i go about finding the solution?
