Question about 1993 Jeep Grand Cherokee

1 Answer

Why does my brake light stay on when my running lights are on?

While driving at night with my headlights on my drivers side brake light is constantly on. I looked under the rear-end and saw that the previous owner made a mess of all the wires that connect to my drivers side tail light assembly. where can I find a detailed wiring diagram for the rear lights?

Auto parts stores have manuals made explicitly for your make and model. It will have the diagram with the color code for all the wires you need.

There could be a fusible link under the hood off the starter relay that is burnt out.

I think I have found the problem. When I wiggle the ignition switch the turn signals and radio go on and off so I feel the issue is in the ignition switch. From what I understand the actual electronics for the switch are at the base of the sterring column behind the lower dash panel and is connected by a rod that may need adjusting.

So...posting your own solutions now???? OK...Just don't forget
who told you to check all grounds (that means both ends of the cable.) I use additional grounding on all my cars...Run a 10 gauge multi strand wire from the battery to the fender, around to the firewall. Branch there and run through firewall to the dash frame support under the lower lip of the dashboard. The other branch continues to l/f fender, attaching to a point where computer ground wires are, then terminating at the cross-bar that runs above the radiator. To make connections to body, I remove insulation but do not cut wire, just loop it around a bolt & re- tighten, then a squirt of undercoating on each. I normally also add an additional ground to one of the starter bolts. I also remove the original block ground wire and replace it with something along the lines of 00 welding cable.(I have a bunch of it from back when I needed it for re-locating race car batteries to the trunk.)

SOURCE: divers brake light does not work with head lights on .

big problem with jeeps 98 and up should be a safety recall but is not; you need to replace the drivers side tail light assembly with a new one, from jeep or auto parts store if available. used auto parts recycler may have one but your taking a chance, used should be 40 to50
dollars new over 100

The brake light on the driver side is not working when the headlight are off, when the headlight are on the are fine.


Replace the brake bulb for that side. The brake bulbs have two filaments. Don't put the single ones. One is for when you press the brakes and the other is for when you run the lights at night it stays on all the time.

Some cars leave a light on if you switch off with the indicator/turn light left on. Put the stalk to the "OFF" position and see if it goes out.

Weird tail light problem


HI Matt,
Your issue sounds like a fault, most likely in the rear lights. Current is feeding from the brake light circuit, into the running light circuit. The most common causes are a bulb filament broken and touching the running light circuit, and loss of ground.
observe the rear lights closely and you should get a clue as to which light is failing....but if not, just pick one....
I would run a temporary ground and test again, if no results, pull the brake light bulbs...
Transient current is often difficult to wrap your mind around, until you understand what can happen.

2007 tail light fuse location honda crv


I had this problem with my 2007 Honda CRV -- all the lights worked EXCEPT the tail/running lights and the license plate light. The other tail lights worked -- brake, reverse, indicators, and hazards. Front headlights also worked, but when the headlights went on the back tail lights did not (not to safe for driving at night!!)
The fuse was #15 in the interior fuse box (under the dash driver side) with the label "small exterior lights" ( also check fuse #19 labeled "small lights main"). The cause of my problem, I believe, is a bad or lose wire in my license plate light.

Mr Pinske,

The rear running lights aren't on the same circuit as the headlight(s). To get the car legal for
night driving, replace the broken headlight (both need to work to drive legally at night),
and tackle the running lights as a separate project.
First thing to check on the running lights - the bulbs. Why: incandescent light bulbs that are
on at the time of an impact cannot withstand the impact and the filaments can fail, so fixing
your rear running lights may simply be a matter of replacing the two light bulbs.
If the bulbs are ok, your accident has caused a wiring fault, which you will locate
between the ignition switch and the rear running lights.
Here's the manual on how to replace the headlight:

Fig. 4: Once the retaining ring screws are removed, the ring can be pulled away

  1. Pull the bulb and ring forward then separate them. Unplug the electrical connector from the rear of the bulb.

To install:

  1. Plug the new bulb into the electrical connector.
  2. Install the bulb into the retaining ring and install the ring and bulb.
  3. Install the trim panel.
Replacing the European style headlights is a slightly different procedure.

There is a shortage some where at the brake bulb and low beam holder. Take off the bulbs and inspect carefully those losing wires attached to the ends can cause the problem. Good luck.

Brake lights stay on only when lights are on


check common rail. maybe the problem concerns with a lack of ground (car chassis), and the return path is made through the other bulbs.
Use a 400-grade sand paper to clean the contacts and the metal part of the bulbs.
