Where is the fuse for the license plate lamp located

According to a post on Traverse Forum, the issue might not be with the bulbs themselves, but rather with the connectors that slide onto the bulb. These connectors may be corroded, which could prevent the bulbs from working . Another possibility is that the lens the bulb attaches to may be full of dirt, especially if you live in a dusty area .

If neither of these solutions work, it's possible that there is a problem with the fuse for the license plate lights. The license plate lamps are powered by the 10 amp left parking light circuit fuse located in the under hood fuse panel. If any of your parking lamps on the left side are out, this could be the problem. If those lights are working, then the fuse should be good. The fuse is easy to get to, so it's worth pulling it out and reseating it or replacing it .

I don't think there is a fuse for them. Have any other features stopped working? Some vehicle features share a fuse so those features would also stop working if the fuse has blown. Check the bulbs are OK as in some setups one bad bulb can turn both bulbs off.

Look at factory wiring diagrams an test electrical circuit.

System Description EKS008NW Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input signal requesting the parking, license plate, and tail lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs power to the parking, license plate, and tail lamps, which then illuminate. Power is supplied at all times ? through 10A fuse (No. 41, located in the IPDM E/R) ? to tail lamp relay, located in the IPDM E/R, and ? through 50A fusible link (letter f , located in the fuse and fusible link box) ? to BCM terminal 70. With the ignition switch in the ON or START position, power is supplied ? through 10A fuse [No. 1, located in the fuse block (J/B)] ? to BCM terminal 38. With the ignition switch in the ACC or ON position, power is supplied ? through 10A fuse [No. 6, located in the fuse block (J/B)] ? to BCM terminal 11. Ground is supplied ? to BCM terminal 67 ? through grounds F14, M57 and M61.

The licence plate lights are part of the parking lights circuit. Fuse port #20 Parking Lamps. This is located in the engine compartment. This fuse box is called a Power Distribution Box. Just in case, this circuit also has a micro relay inside the same box. This particular micro relay is #55.

are the bulbs good ? Do the tail light's , park light's work ? These light's all come on when you turn the headlamp switch on to park lamps or headlamps .

Turn ON the park lamps.
Observe the license lamps.
Do the license lamps operate properly? Yes - No
No ? Go to Step 3
Do the park lamps operate properly? Yes - No
Yes - Go to Step 4

Remove the inoperative license lamp bulb.
Connect a test lamp between the instrument panel lamp fuse supply voltage 1 circuit of the inoperative license lamp bulb and the ground circuit of the inoperative license lamp bulb.
Turn ON the ignition, with the engine OFF.
Turn ON the park lamps.
Did the test lamp illuminate?

same fuse for the tail lights

Well its the same fuse that powers both tail lamps.
There is a lamp relay involved, but if the tail lamps work, the license lamps should also have power.

The fuse labeled REAR PARK LP 15A in the right instrument panel fuse box powers the rear park lamps, and the tag lamps. If your rear park lamps are working then you most likely need to replace the tag lamps (bulbs). Use the following procedure to replace the lamps.

To Remove:

1. Remove the two mounting screws from the license plate lamp.
2. Remove the license plate lamp from the rear bumper fascia.
3. Remove the license plate lamp socket by turning it counterclockwise.

To Install:

1. Install the license plate lamp socket by turning it clockwise.
2. Position the license plate lamp to the rear bumper fascia.
3. Install the license plate lamp mounting screws.

Have you checked for power at the socket? But most vehicles do have 2-3 fuse panels; in different locations.
