    The brake lights do not work even after changing the bulbs first the right side was out and now the left. I ended up changing the whole tailight assembly on the right side but I want to avoid that if at all possible this time . can you help?

I hand the same problme on my 2000 jeep. It is not the bulb or the whole assembly, but the socket connection. I played arouund with the metal contacts on the socket itslef. I plyed around with the metal strips that make contact with the bulb and fixed the problem. took 15 min. total cost 15 min of my time.

A relative of mine had the same problem on a 2000 Grand Cherokee Limited. The problem was the socket that the light bulb goes in itself tends to burn out. They brought it to a place only to find out they were trying to rip her off because "she needed new tailight assemblies" and would cost $216 I was skeptical, but I took a look myself. I moved the "non-working bulb" from the brake light socket and put it in the reverse light socket. The bulb lit up and found out it was the socket because it seemed blacker and "burnt" compared to the other ones. Went to the dealership and the sockets cost $10. Works fine now!

Check the brake switch under the brake peddle it looks like a little box takes 5 min very easy and cost is very low hope it helps

You need to purchase new back light assemblies. They have a chip in them that goes bad. They are sealed so you can't repair. About $100 each. I did both of mine about 3 months ago.

Does this vehicle have a trailer wiring harness maybe the problem might be tied in with that if not check that your ground has a good clean contact also test the socket with a test light make sure the bulb is really good hope this helps.

Two lower break lights not working (top on in the back window is)

Power for the brake lights travel thru a light failure sensor which could have failed. The third brake light does not involve the sensor.
If both brake light bulbs have no voltage, the sensor may have failed.

Brake lights not working

Not even the third eye? then the fuse is blown or all the bulbs are out or the brake light switch on the break pedal is bad wire off or broken( it breaks right off the plug then crosses then blows the fuse as the loose broken wire hits the brake pedel arm. Test the break pedal switch first if the third eye doesesnt work either. no power with a test light the fuse is blown or the wire broke ( the wire goes straight to the switch from the fuse and doesnt go anywhere elese. the other wire if hot should light the lights. Most of these wont come out of park without this working as the wire also turns on the park release but some Fords the park release sticks released and Ford made em that way as they didnt like the brake to get out of park law. If the brake lights dont work maybe you ought not be able to get out of park anyway till its fixed. the switch is hot on both wires with the switch pused down and the lights dont still work go after the third eye first if the bulbs are bad change em before you do the rest of the work. on cars with yellow turn signals the brake lights all work on the same wire but red only use three wires, but you didnt say the turn signales didnt work if they work and they are red you r on the way to the turn signal switch as the brake switch powers the turn switch with power then it splites it fot the two lights and adifferent switch circuit for the front hooks them all together for hazard. yellow turns in the back or even separt bulbs can mean blown bulbs ther too its old enought for all the bulbs to fail and the runs still work.

No brake lights

It is not the brake switch as the third light works. If the lights work when the hazard lights are on then it is the turn signal switch. If not then I would check the bulbs and then the relay and fuses.

Tail break lights don't work. Window break light does work however. Bulbs have been replaced.

Check the brake light fuse. The high mounted brake light (third brake light) is on a different circuit than the brake lights. Hope this helps.

Malfunctioning brake lights.

Most likely a short in your break line. You might also check the brake switch, but I would think if the break switch was going, it you wouldn't even have the third lite working...

Break light problem

Do you know if the brake light bulbs are working? (are the bulbs good?). (the bulbs have two parts, one for brake lights the other for running lights)
If the third brake light bulb is working the brake lights should be with good light bulbs.
