I have recently purchased a 1986 cherokee only to find that the tail lights dont work. The brake lights, turn signals, headlights all work fine...but no tail lights. All the fuses and bulbs are good...any suggestions before i hard wire them to my headlights?


I did a search for tail lamps and saw that someone was having this same problem..however they never really said how they fixed it..lol

 

anyone?

 

bump..i really need some help with this..lol

 

 

ok, so just to clarify, the taillights work, except when you have the headlights on they don't light up like they should? perhaps check with a voltmeter, and see if there is voltage getting there (could be a ground issue)

 

negative...the tail lights dont work at all..not even with head lights on

 

ok..so today i pulled every bulb from tail lights and marker lights, along with all the instrument lights..all was good..while i had all the lights out, i put the fuse back in the box for the tail lamps, and turned it on..again the fuse blew..i went and got a new head light switch, same thing... Im really starting to get agrivated.. can anyone help?!?!

 

Yeah I recently have the same problem. Everything works fine except my left rear marker/tail light does not work. I replaced the bulb and still nothing. My brake light works when I step on the brake pedal, as well does my reverse and blinker lights. For some reason the tail light does not work when I put my lights on.

 

i had the same problem when i bought my 1990 limited. what you have to do is disconnect the lighting harness and check each wire with an ohm meter. the harness is behind the driver side kick panel. what i did was just keep unplugging connectors untill the fuse didnt blow. once the fuse doesn't blow you know you have isolated the short. mine had a bullet connector for the liscens plate light that was sorting out so fixing that solved my problem.

 

do you have a trailer plug wired in? you may have a bare wire thats grounding out on the body,or a broken wire somewhere.

 

also forgot to mention if you have a trailer lighting harness those can short out too. but you just have to keep testing for shorts good luck

 

you have gave me hope..lol
let me go get some tylonal and get to work!!!!

 

X2 check trailer light wiring, if not equipped check all grounds for the tailights from the fuse box back
