Hi, it sounds to me like your brake light switch has either failed or come loose.

to find your brake light switch you need to get on your hands and knees so that you can have a close look at the brake pedal,
then look closely at the brake pedal and follow it up to where it goes through the bulk head into the bonnet, now you should see the brake light switch attatched top the top of the brake pedal, it should have a couple of wires going to it.

its hard to see so make sure you have a good look but it connects to the base that the top of the brake pedal is joined onto then when the pedal is pressed this then pressies a little button on the brake light switch this then switches the brake lights on,
now it can come loose so check this but most often you can use tape on the brake pedal to take up some of the slack that has built up over many uses, or you could just replace the switch.

let me know how you get on or if you need further assistance ok

    you no when you replaced the switch did you try operating the switch by hand by pressing the button in on the switch, it may be wort trying just to rule out any ware on brake pedal causing the problem, also check its adjusted properly because if the brake pedal is not pressing the switch far enough in then this could cause your problem.

    it might also be worth checking your fuses and replace any that are blown.

    the only other problem that could cause this is corrosion inside the back lights, you could remove the rear lights and check the board that the bulbs go into as water can get in here and cause corrosion making the lights short out so have a look and let me know what you find

On the 1997 Chrysler Town & Country LX, 3.3Litre, the tail lights don't work. The break lights work, the turn signal works also. It's not the light bulb.

All three of your lights on the rear are ran separately. The tail lights are ran with headlight switch the brake lights off the break sensor the turn signals are ran from arm switch and then there are relays as well. Electrical issues are a real pain to track. However that's not abnormal have 2 of the 3 working when theres a bad relay or short in the wire

Tail light doesnt turn on with headlights but works fine as a break light and turn signal, why?

in the rear lights you may have two bulbs one is the turn signal the other one is stop light / tail light the stop light / tail light has two filaments, one for the stop light (21 watt) & one for the tail light (5 watt) it is possible that the tail light filament is blown, try replacing the bulb to see if that fixes the problem,also check all the fuses as well.......hope this helps......cheers.

My tail lights dont work or break lights but when i depress the break pedle my cargo break light works...i drive a 02 GMC hazards, turn signals, and back up lights work

It sounds like you have burnt out bulbs. All those other lights that you say work are all different bulbs. The tail light bulbs have dual filament so that they can perform the tail light and brake light function. You should change out your bulbs and that will probably solve your problem.

No break lights, tail lights or blinker on passenger side

check fuses with a tester. just because they look good can be missleading

No turn signals, no tail lights and fuses are good

Replace the non-working tail light bulb. Try replacing the bulbs for the turn signals. If that doesn't work, replace the relay.
