Problems With Brake Lights Due to Damaged Electrical Contacts on Jeep Grand Cherokee

Problem Description and Possible Solution

Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.

I have had a tail light/brake light issue ever since buying my Jeep used in 2004. I have replaced the sockets, used aluminum foil as suggested as numerous forums and last February eve bought an entire rear light assembly. A few months ago the passenger side tail light stopped working again. I can't figure it out and am afraid of being ticketed or worse, involved in an accident. So disappointed in Jeep for not coming up with a solution to a KNOWN issue.
all rear lights work untill you push breakpedel,then the pass-side will go out.let off break pedel they come back on.
When the head lights are on the left brake light will not work.
When my lights are on and i hit my brakes my one break light doesnt work but when lights r off my brake light works
All of my lights work, but as soon as I hit the brakes my lower lights go out and the high mount comes on.. ive tried replacing the actual holder for the bulb, and next is the actual circut board. I havent found a fuse yet that is blown... any simple solutions I can try before spending money on the circut board?
Hey,
So I've had the problem with the right tail light in my grand cherokee 2004;
When the lights were on, the brake light wouldn't work. I couldn't solve it until my turn signal/hazard light stopped working as well.
Replacing Turn Signal Flasher that's next to the steering wheel solved all the lights problem.
It was only $32, find it on parts geek website, good luck!
Brake light won't work when headlight are on.tried changing the bulbs but did not help.
Passenger side: when hit brake lights no lights work on passenger side, no talilight or brake light have swapped sockets with driver side, see alot of rust around contacts where sockets twist in or passenger side, the driverside is fine. Also turn signal quit working, twisting of socket got it to work and some smacking on the back of taillight (circut board) but now cant get reverse lights to work. Think im going to have to get new taillight or get new circut board on passenger side...having problem unplugging wire harness from it now..will hopefully find help so I dont have to take to expensive mechanic..
Due to the housing being plastic the contacts pull apart due to melting. I have replaced the entire light bar twice, at a significant cost, and replaced the socket only on two separate dates. When the light goes out now I open the contacts again until they can make a complete circuit. This however is only a temporary fix, sometimes it will last for several months. Jeep is aware of this problem but will not retrofit due to cost on their end.
Driver side brake light out. Followed instructions found on-line to pry up contacts with flat head screwdriver. No problems since...approx 6 months ago.
Had problem for years with rear passenger side light brake light burning out.
Finally went to a salvage yard and got a replacement light unit..end of problem.
Examination of the old unit revealed fused metal on light contact with unit, apparently
shorted and overheated breaking the contact
tail lights not getting ground added a ground brake lights want come on when i push brake pedal
Both running lights work but when I press the brake pedal the drivers side brake light works but the passenger side light goes out completely. WTF?
Left brake light goes out when I push the brake pedal. Have replaced light 3 times and entire thing once. still the same problem
Passenger tail light. Cosmetically perfect on the outside. Burnt and melted connection on the inside. Now only get either working tail light or break light, but never both working together. Fire hazard? Not sold as separate parts. Disappointing.
Rear brake lights keep going out.
Driver side Brake lights will not work. Power lockes will not with the exception of the drivers side.
Brake light goes out always on passenger side. Replace circuit board worked fine and is now doing it again.But with a good tap without breaking tail lens cover it starts to work...Also put bulb connector grease seems to work until it disappears...ITS A JEEP THING I guess
Passenger side brake light works until I press the brake
I'm not sure exactly how it was fixed but the right tail light kept going out on me and the mechanic had to "clean up the wires" whatever that means. It cost me about $150.00 to get it fixed.
