Wj !!!!!Brake lights stop working with headlights on!!!!!!

Have an issue with my '01 Grand Cherokee Laredo where my brake lights will not illuminate when the headlights are on. The brake lights work fine without them on. The tail lights are illuminated when the headlights are on but go off when the brake pedal is applied, leaving me without tail lights or brake lights.

Could this be a fuse or wiring issue? I have looked at several fuses that I thought might be related but the ones I looked at seem to be fine. If anyone has any idea please let me know!

UPDATE: For anyone who wants to know I have found the resolution to this problem. The piece that holds the bulb for the brake and tail light has a power and ground that it makes contact with when you insert it. If you pry those small pieces up just a bit and clean them up well it will solve the problem. Another post also suggested using a solder to make the contact point larger. I did not try this method, but the other individual said it worked for them.

I had the same problem with mine. In a pinch I just switched my reverse light plug and bulb and all the lights worked fine.

We had the same problem of the lights going out when the brake was pressed, but work fine with the head lights off. Just did the solder method on my sons 1999 Jeep Grand Cherokee and it worked! Thanks

I did use the forums search function, that is how I found this thread to learn to try to solder.

Yes and there are countless threads saying the same thing.

Madbulldogs,
Do you experiencing this at night, day or all the time? If you have day time running lamps on your vehicle the headlamp will turn off to increase turn signal visibility, per page 154 of your Owner Manual.
