ML350: the interior lights do not come on when I open the doors

This answer was rated:

Hi, I own an 04 ML350 and I changed the battery recently. Now, the interior lights do not come on when I open the doors. What happened?

eurotec :

Hi Jake, have you checked to see if you can manually turn the lights on and off using the overhead switch?

eurotec :

The switch must be in the middle position for automatic function.

Customer:

Yes. Did all that per the manual.

Customer:

Tried to turn them on manually and that doesn't work either. Switch is in the middle position.

eurotec :

Ok, do any of the interior lights work? Do the reading lights or the map lights work?

Customer:

No interior lights work however, radio and radio lights work. Instrument light with speedometer and all gages work. Power socket for recharging cell phone works.

Customer:

No reading or map lights work.

eurotec :

Ok, can you post your vin number so I can look up some diagrams?

Customer:

Vin 4JGAB57E24A512383

eurotec :

Ok, it looks like fuse 13 in the main fuse box under the hood is responsible for those lights.

Customer:

I was told on the phone by a MBZ mechanic that something needed to be reset and that if I disconnected the neg end of the battery terminal and let it sit and then reconnected it, it should or could reset and lights work. Not a guarantee though. Performed as he instructed and no changes. :(

eurotec :

There is no reset needed.

eurotec :

Check fuse 13 under the hood.

Customer:

I am looking for fuse 13 now.

eurotec :

Ok, I sent you a picture

Customer:

You are a miracle worker. Changed #13 and lights work. Thanks. How do I make sure you get credit for this?

eurotec :

Excellent!
