I bought an ultra blue 90 gt..love the car, but the blinker fuse continues to blow. Sometimes it blows immediately and sometimes i get a few days of blinkers and back up lights. Right now the blinkers will work if i change the fuse but the fuse blows INSTANTLY when I put it into reverse. I know the back up lights and blinkers are tied to each other. THis is what I've tried so far with out success....
]Bought bulk package of 15 amp fuses (almost out)
]tried higher 20 amp fuse (still blows)
]disconnected alarm (still blows)
]disconnected backup light switch to T5 (car would not start when i did that)
Anyway to isolate the back up lights or disconnect them besides what ive tried...any other ideas or help into this mystery.
mine is doing the same thing, but now its to where if i go ignition on it blows the fuse...thinking about getting a 15amp breaker so i can reset it instead of changing fuses while i'm troubleshooting it

OK you have to remember that those wires run inside the engine bay and they run across areas where the metal is sharp. The insulating material on the wires over the years can finally rub through. I would check the wiring up in and around the headlights. I am guessing the only time you have issues is when the blinker is activated or the lights are turned on? Good place to look.
ok its like 6 months later and Im still driving without turn signals. (i got tired of replacing fuses.) What I can say more specific is that my signals work with a new fuse every time I replace it, but the fuse seems to blow every time I shift the T5 into reverse. Im assumming its a short in the backup switch, reverse lights or wiring in between. Can anyone tell me how to locate this wire and trace it from start to finish? Whats the color code?
