    Default reverse lights not working

    I have a 1985 Cougar 3.8l v6 with a C5 tranny. I recently replaced my transmission and my reverse lights worked fine for about 2 weeks then they stopped working. So I replaced the neutral safety switch, and still nothing. All fuses are fine. Turn signals still work. I am stumped. I hope someone can help.

    Have someone watch the backup lights as you move gear selector through P-R-N-D. See if they ever come on. Maybe the linkage is a little out of adjustment.

    I have tried that. They don't come on at all. The bulbs are new LED's that I just put in, tested them in other sockets and they work just fine. Could switching to LED's have something to do with it?

    Don't know why LEDs don't work. Can you put the 1156 bulbs back in?
    Check for voltage at the bulb socket with your multimeter.

    I had an LED 1156 bulb burn out when I tried it...very possible they blew. As softtouch said, try the regular bulbs.

    I have tried all that. No power at the socket. And the regular bulbs don't work either. Both sets of bulbs are brand new out of the pack. Thats why I'm stumped. I have tried everything I can think of and consulted with a couple mechanics I know and they were stumped as well. Is there a relay somewhere that could have gone bad? If so where is it?

    The reverse switch is seperate from the neutral safety switch. It is a single two pronged sensor with only two wires going to it. Make sure it has power going to one side of the harness, otherwise its not the reverse switch, it will be an electrical gremlin in the car somewhere probably.
