Hi all,

I am having a strange issue with my 2006 LR3 which I cannot chase down, hoping someone here has some insight.

As the title says only my tail lights are not working. Brake lights (all three) are good, reverse lights function, headlights low and high both work.

No dash lights on, break switch replaced, all new factory bulbs replaced, checked literally all of the fuses at this point. Opened up the cable chases and can’t find anything broken off anywhere. No codes with GAP tool.

Anyone have any thoughts? Driving me nuts!!

 

You say all other lights work, but you didn't mention if the front marker/side lights work. Also check the License plate lamps. They are on the same circuit, so its important to know if they work or not.

 

Sorry license plate light does not work, side lamps work when blinkers are on but also do not light up otherwise.

 

In the underhood fuse box, check FL15. Its a 40A, green, square fuse. This fuse powers the two relays that control all the lights that do not work.

 

Was this sudden or after a lamp change?

 

Hey Guys,

It was a sudden change. I had checked all the fuses already however I just went back out and checked continuity on f15 (and f16 just as a sanity check) and they both read less than 1ohm across the pins. To humor myself I swapped the two of them out as well without any change.

 

Simple check, using voltmeter see if you have 12 volts at the rear lamps as you may be missing an earth.

 

Do you have voltage at F15?

 

I do have 12v at the center side of f15 with the fuse pulled.

I did check the tail lights originally and get 0v at all pins. I was trying to chase to see if I could find any shorts but I can not find any. Didn’t know if there were any obvious junctions/points of failure I should be looking foreword

 

Try cleaning the contacts in the bulb holder with emery cloth etc.
