i have a 97 civic the wires are all hidden and somehow my tail lights dont work but my brake lights do. Headlights still turn on and work and the fuse for the tail lights isnt blown. Im thinking a short somewhere on the harness but i dont know how to find it or if theres an easier way to fix this problem

 

Do the dash and cluster lights work when the light switch is turned on?

How did you test 7.5A fuse 32 under the dash?

 

yeah everything the only lights not working are backup lights running tail lights and license plate lights

 

------------------------

 

oh i pulled it and looked at it and saw no break then i used a circuit tester and both sides of the fuse gave a power reading so idk

 

With the light switch turned to parking lights, use your voltmeter to test for battery voltage to body ground at the Red/Blk wire for one of the taillight bulb receptacles.

 

Whenever something doesn't light up, always check the bulbs first. As the dash lights light up, that shows the switch, fuse, and most of the wiring are good. If the lights on the back are on a moving hatch or trunk lid, the wire could have broken where it flexes when the lid is opened.

 

i used a test light at the bulb on my tail lights and i get no power unless i press the brake. is there a relay for running lights and im not talkin about the fuse? and i dont know how the wire could have broken if the lights still come on wen i press brake

 

Test voltage at the Red/Blk wire NOT the Grn/Wht wire.

 

i found out today theres a security system on my car the previous owner put in, they changed some of the wires wen they put it in and i dont know if it may be connected to that somehow. Ill test the red/blk wire tomorrow and c if i can find a short in it or its origin
