Left rear Tail lamp not working (bulb and fuse is fine)

I noticed that the left rear tail light was out so i changed the burnt out bulb. A couple days later I noticed that it was out again but the bulb was fine. I checked all the fuses but cant find a problem. The turn signals seem to blink quicker than usual as well. Where would be a good place to start looking for a problem.

    Ok, I tried both and nothing for either. There is something else that I noticed. When I push the Lock/Unlock button on the remote ONLY the right side lights up..but when i put my left blinker or brake on..the left lights up fine. could there be a bad relay or something somewhere? The small bulb doesnt ever work at all.

Check to see if the yellow wire is broken at the connection right below the lights. I just had to repair broken wires on both sides where they had broken off at the connections

If you have access to a simple 12 volt test light, you can remove the bulb you replaced, turn on the turn signal and park lights and see if the test light lights up. If the turn signal contact blinks the test light and the tail contact lights the test light, you know your power supply to the bulb is good.
Next you will check the ground.
Using your test light, carefully touch the tail light contact with the test light tip and touch the test light ground to the socket ground. If the ground is good the test light should light.
Let me know what you find and we will go from there.
Regards,

My left side tail light doesn't work after changing the lamp. Jeep 2007 - Commander


it worked before the change out?
there are 3 things that are first. on advance electronics, cars. like this. 2007 is 1st year, of wild complexity.
  1. check fuses first. MIP fuse #8,9,10 (8 is left) check that?
  2. check action of park relay
  3. check for trailer wiring hacks (do you have factory hitch option?)
  4. and scan the PCM , do you see any park fail DTCs'
DTCs are system errors.
that is first.
next if not solved, we look in the FSM for that chapter, and the schematics, to see how its is structured. (varies by year, car)

FSM JEEP XK 2007 (book)
factory service manual.

left side rear tail (park) (tail is old name , car has many park lamps now , not just 1 or 2 tails like in the old days.
so it park and the relay of same name.
there are front parking lights too... do those all work>?

my guess, is you didnt check fuses first.
am i right?
fuse 8 is blown?
but that takes out front left park
and left side marker (park ) lamps too.
so did you look at all left park lights first>?

i bet not, if im wrong then you do have wiring errors.
or the new lamp from china is shorted inside, (common)
try one more lamp , like from GE or Philips.

Why taillights do not come on, but the brakelights and signal lights work


check the fuses for a burnt fuse. the taillight circuit has its own fuse and wiring. its possible the headlight switch is bad but this doesn`t happen very often.

2000 Acura 3.5 RL suddenly has no tail lights or tag lights. Brake, reverse and blinker all work. Checked fuses-all appear fine. Decided to replace bulbs and noticed front right marker light out so changed...


The only thing that both the brake lights and tail lights use is a ground connection. Keep in mind the warning light on the dash may be for any exterior lamp. You may need to check the sockets and grounds on all four corners of the car.

I have a 2004 Chevy TrailBlazer that just developed a problem with the left turn signal. The left turn signal indicator on the dash is blinking rapidly and the tail light turn signal is out. I change out...


The Trailblazers have a common problem with the printed circuit boards in the tail lamp housing.
Unplug the tail lamp housing at the wiring connector and test for power with a test light. ( With turn signals on) You may have an open circuit in the lamp housing circuit board. Good luck

Rear tail lights/Dash lights keep blowing fuse why would this be ?


There is an electical short somewhere in the system, it could be a power wire shorted to ground, or one of the components has failed and caused or created a short. (burnt wires in circuit or in part)

Right brake light out; tail light works fine


most rear tail lights and turn/stop lights are the same dual filiment bulb. it is possible for your tail light to work and your brake light not to and still have a bad bulb. I would check the bulb first, your brake light works on the left yes? this would mean that the fuse is fine

Left rear brake light stopped working but bulb and fuses are OK.


These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!

''96 Silverado no tail lights.


if that doesn't help, you might want to check the bulbs. the damage might have shorted which burned out the bulbs. but you do have one wire that runs to the rear and splits off to the tail lights. the wire should run back to the head light switch via a fuse. the headlights have its own relay. but i hope it is just a fuse.
