So I have an 84 CJ7 and the Brake lights I get nothing but the tail and turn lights are ok. Any ideas as to why?

I have replaced the brake switch, and that did not make a difference. Once I got the switch out I found out that it was working just fine, and did not need to be replaced. (But for a five dollar part and something had to go back in, I just put the new one in anyhow.)

What else should I be looking for?

I know that the two side marker lights on the FRONT are not there, the socket broke and so there is nothing in them anymore. I have some lights I could use to replace them, but I can not tell which wire is hot and which is not. (It has a white wire and a white and green wire.) Someone had mentioned to me that this may be a concern for the rear lights but I do not know why.

With the tail and turn lights working back there I should think that they are getting a good ground, I would assume they are on the same ground, yes? Same bulb after all.

Thanks. I need this jeep for a daily driver in two weeks, so, any help would be VERY appreciated.

Brian

Sorry, I forgot to mention that I have replaced the bulbs recently.

might be a double filiment bulb, ive had that issue before in some older cars, it was headlights, but still same idea, the low beams didnt work but the high beams did, if the filiment for your break lights is the only thing thats burned out your running lights and blinkers might still work... not 100% sure thats the issue but thats my $.02

Not exactly sure what you mean there.

I did try to put the ohm meter in there, one on each side, but I did not get anything.

But I have no idea how I might check that wire. Can you elaborate please?

I did try to visually inspect the wires and they all looked ok to me (running from the front of the vehicle to the tail lights themselves).

Thank you so much for your help. I found the problem. Of all things it was an in line fuse that I did not know was there. If I had not known to trace the wires I never would have found it. Thanks a lot!

Yup, first bulbs, then fuses.

That was my guess... Mr. Green

i was meaning the wire that goes from the break pedal to the relay box above it, but if you already figured it out great!
