Turn signal issue
Ok so heres whats going on. The car sat for three years and I just now have
brought it back to the road. The pass front turn signal would not light up at all whether it was with the hazards or turn signal switch. I replaced the bulb, flasher, headlight switch(other problem now fixed). I now have all the signals working with the headlights off. When I turn the headlights on both front turn signals stay on and do not flash, rear ones work fine. I'm thinking there is a broken or crossed wire somewhere but before I start tracing that I was hoping someone had a simpler fix. Any help or direction would be appreciated. Thanks guys.

Re: Turn signal issue
I found the issue. The new bulb I had bought must have been faulty. The wrong filament was lighting for the marker and the wrong filament for the flashing.They were lighting up backwards. Replaced the bulb and now it works.

Re: Turn signal issue
The bulb i used for the turn signal is a 2057na. I realized it was a bad bulb and was then working. I now realize that I have a second issue with probably a bad connector because it has reverted to my original problem of not lighting up at all after driving home. The bulb though must have NA on the end of the number to be an amber bulb otherwise it will be clear.
