05 Pontiac GA, rear lights work brake,turn,reverse,but on both sides,taillights will not idea what could affect both sides & only taillights.changed all bulbs,fuses that i know of didnt help.

Park, Tail and Marker Lamps
The park, tail and marker lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or HEADLAMP position, or anytime the headlights are requested. The PARK LPS fuse in the underhood junction block supplies battery positive voltage to the auto park lamp control relay switch contacts. The PARK LPS fuse in the underhood junction block also supplies battery positive voltage to the auto park lamp control relay coil. When the park lamps are turned on the body control module (BCM) energizes the auto park lamp control relay. Current flow is from the auto park lamp control relay to their respective park and marker lamps and to ground. Ground is provided at G101, G401

Just the back light's - tail lamps ,park lamps , sounds like a wiring problem or faulty connector . Viewing wiring diagrams an testing the electrical circuits is the way to find this problem . Free wiring diagrams here Enter vehicle info. year , make , model an engine size . Under system click on lighting ,then click on parking lamps under subsystem . Click the search button then the blue link's . Watch these videos an then test the electrical circuit for the rear park lamps .

My 2005 Jeep Cherokee Limited 4x4 hass no taillights or rear blinkers. Fuses are good and replaced the connector plate.

Click on the link.
Did you check voltage and ground for tail lamps? Use a test light, lamps on. On one side the wire color for tail lamps, white with brown tracer. The other side, white with dark blue tracer. The black wire is ground. Did you check for voltage at applicable fuses, lamps on? There is a park lamp relay. I'm not saying the relay is faulty, I'd have to check the relay circuits, first.

Why don't taillights work?

please be clear.
tail/ parks are dead, but parks on front and sides ok?
not brake lamps.
not turns, failing.
not reverse lamps.

only the rear of car lamps are dead. in park selected on the stalk, right?
every thing else works (matters this in electrics, all cases )
btw the FSM book is $4 to read, online. see link at end.
no need to be helpless with $4 in way.
the pages tell you 2 things how it works and where to put voltmeter probes.
rules for this car , seen at mitchells.
1: BCM car, (means the lamps are computer controlled)

the tail fuse is fuse 36, and if looks ok we test it
way because looking ok can be hair cracks.
so its got 0 ohms in hand or 12vdc both sides in car.
the fuse runs headlight #2 relay, (but is tail relay in truth)
see it in the schematic i do....
the BCM sees you turn on parks. at pin 9
then the BCM , energizes a transistor that in turn
engergizes the HL relay 2, and all park lamps glow.
my guess, you dont know there are 6 lamps.
so is the relay closing?
if not scan the PCM to see if there are BCM errors.
not scanning , now, can be endless tail chasing on all modern cars.

The BCM grounds 1 HL#2 relay pin to energize said relay
this is what i look for first.

if other 4 park lamps work, now's the time to say so.
as that is , a horse of a different color....

the real book is here for 4 bucks

How can I take off the tail light assembly to replace the bulb for the left tu

Open the trunk. In the left corner where the lamp assembly is, you should see two screw covers that cover the screws holding in the lamp assembly.


Remove these covers to find the screws, and unscrew them to pull the taillamp assembly out of the vehicle body. Disconnect the lamp wiring harness, turn the bulb socket counterclockwise to pull out the socket, revealing the light bulb. Then pull the bulb right out of the socket and replace it with a new bulb.

Replace the socket, turning it clockwise. Replace the taillight assembly. Check that the taillamp assembly tab, located at the bottom of the taillamp assembly, is aligned to the facia bracket before securing the screws.

Screw the taillamp assembly back into the vehicle body and replace the screw covers. Check to make sure the new bulb works properly.

Your owners manual specifies that the rear left turn lamp is a lamp with bulb number 3057K. You should be able to find them at any automotive store or from your dealer. Hope this helps.

2005 accent tail lights wont shut off

Pull that fuse or pull tail lamp relay, that should kill the lamps till you figure out the problem? You also have left an right tail lamp fuses, underhood fuse box. I don't know if tail lamp relay is faulty? Another concern, see the bottom wire on left of tail lamp relay, that is a ground controlled by the headlamp/multifunction switch, there could be a problem with that wire circuit or the multifunction switch. At the moment, I'm hoping just faulty relay.

Where is the taillight fuse located?

I do not have a fuse layout diagram but can tell you where the actual fuse is. Below is a picture and where you see the integration box or J/B No. 1 is the fuse panel it is in and is the one marked "tail". BUT (and there's always a but) If you look in this same picture you will notice a tail lamp relay which also could be bad. Now to top that off there is a fuseable link for that relay as well. If you are able to see any wires going to the connection of that relay, the white wire should have constant power (key on or off). If you do not have constant power at the white wire or if the relay has numbers on it, it will be number 1. In any case if you don't have that power, then you most likely have a blown fuseable link and will have to trace that white wire back towards the battery to locate the link that is bad. I hope I was able to help out and hope your just dealing with a fuse issue and by the way it should be a 15 amp fuse.
