Why do my rear lights stay on when the car is off?
My rear lights stay on continuously whether I'm in the car or not.
The Jeep Cherokee (XJ) is a compact SUV that was manufactured and marketed by Jeep from 1997 to 2001. Sharing the name of the original full-size SJ model, but without a traditional body-on-frame chassis, the XJ instead featured a light-weight unibody design.
I would look for a switch hanging. If the problem is brake lights check the brake light switch usually by the brake pedal. If not get a repair manual from Auto Zone or someplace like that with a good electrical diagram in it and trace put the circuit that's staying on. Ralph
I actually came across this issue a little while ago. You see when the brake is in the depressed mode the light comes on (as it should) but when not pressed it sort of sits on small bit of rubber the size of a pea. Look at the pedal arm itself - about 4 or 5 inces up the arm you will see a small hole where a rubber used to be (if light stays on means it has fallen off). I actually did not bother to find the correct part but you can stick any plastic or rubber that stops the pedal arm from touching the metal bit where is sit when not pressed. Hope this helps.
sounds to my like there is a bad connection from (-) to the chassis somewhere. In this case the (+) from somewhere else is using the (-) connection of your rear lites and that's the reason why the stay on all time.
If you know how to use a multimeter follow the wires backwards an see where the (+) comes from. I would guess, somewhere from the ignition switch and/or light switch. There you will find the bad (-) connection to the chassis.
If it is the tail lights that are inop there are some common problems associated with this model Jeep. The most common is the tail light sockets. They often melt the housing they fit into and consequently lose ground. The only way to properly fix this is by replacing the entire taillight assembly''italic text''. They have come way down in price and I'm sure by now there are aftermarket solutions. I usually don't use aftermarket electrical parts, but Dorman has made some good stuff and proved me wrong. The very first thing I would check is that the instrument cluster lights are working when the lights are on. If not, check the fuse-they are on the same circuit. It could be that simple. Keep your eye on the cluster lights-when they're not working,neither are your tail lights!
If you have the fancy "Automatic " lighting system it can get a little weird. There was a big problem with BCM's (Body Control Modules). When they go bye-bye, you might think that your Jeep is possessed! The lights will flash on and off in the middle of the night! Unfortunately you will need some specialized equipment for this. The BCM isn't that big of a deal, but you will need a DRBIII factory scan tool to "marry" the BCM to the Jeep.
If I had to make a wager, it'd be the sockets and tail light assemblies. It's a very easy repair-pop the hatch and remove a couple of screws. The assemblies used to come with brand new sockets and bulbs. Plug n play!Love me some Jeeps!
Carefully look at the socket for the rear tailights and all lights on that circuit. You may be getting a poor ground or corrossion is causing a ground feedback. Hard to diagnose something like this from afar even with 10+ years of factory training on Jeeps. Does anything change if you have the brake lights on? This is a ZJ model right? If its a Grand Cherokee that changes everything except looking at the light sockets and associated wiring. Does your Jeep have a trailering plug? That can also create some havoc. If you want to give me the VIN number I'll dig deeper. If there's a way to privately message on here I'll give you my phone number and help as much as I can.
Hi, I normally don't join forum's but after reading on this sight things to check ( I am mechanically inclined to a point) just was looking for things i may have not thought of. I suspected the brake switch just like some of you!
Excuse my grammar graduated years ago so no teachers to impress! lol. Anyway sure enough the rubber contact point was laying in a pile on the floor mat! I looked at the brake pedal after charging the battery! and sure enough the contact had disintegrated and there was a hole where it used to be attached. I went and got a quarter inch bolt and slipped it in the whole and viola! problem solved. I inspected it again and noticed to the left about 1 inch away was the same rubber grommet and a nut where I could have moved the brake switch over to the left and re attached it like nothing happened. After a few choice words I stood in shock as my thoughts of repair shops and dealerships using such a short cut to take advantage of some of us to a high repair bill! This fix seriously took me 10 minutes! It wasn't complicated or rocket science. I am glad these forums and the internet does have value! Hope my rambling may help someone else in the same situation.. Forgot to mention this fix was a 1997 Nissan Pickup. This may help fellow Nissan owners. Good Luck
