S CL Class W220 Fuses and Relays Location Designation 2000-2006

Application: W220 S430 s500 s55 s600 cl500 cl600 cl55

Years:2000 2001 2002 2003 2004 2005 2006  A 000 545 18 00 w220 215

Look up the fuse assignment and relays for the S and CL classes. If you find a blown fuse, replace it with the same color. The S and CL classes use the fuse types shown here. If you need the proper fuses type for your Mercedes, you can order a box of 120 for less than $10 on Amazon; see the link here.


In the S CL-class, these fuses are located in the following places:

Fuses 1 through 27, Relays A B C D E F G H I J: are in the engine compartment left side/driver side. Open the hood and look next to the hood hinge on the driver’s side. Remove the black plastic cover, and you will see these fuses.

Fuses 28 through 49, Relays O N M L K, are in the right/passenger side engine compartment. Open the hood and look for the black plastic cover next to the hood hinge on the passenger side. Main fuse box w220

Fuses 50 to 77, Relays Q R S T U: are located in the fuse and relay box under the rear seat on the passenger side. Remove the rear seat and you will see these fuses and relays. fuse chart box diagram location w220 s-class


Here is the list of the fuses in your S / CL-Class. As I mentioned above, some of the slots may be empty. Your car will not have every single fuse in this list.

The S and CL Class have always been Mercedes-Benz flagship vehicles. They always had the most advanced technologies on them during production, and the W220 was no different. They have so many electronics that fuses can’t blow. Remember that under the regular operation of a specific circuit, the fuse wouldn’t blow. So if you find a blown fuse and it blows again shortly after you replace it, then you should look for an underlying problem to the corresponding circuit. We have provided the list below, covering all 2000-2006 CL and S Classes. Please comment at the bottom of the page if you find any discrepancies.

The best way to test fuses is to remove them and visually inspect them. You will see a broken wire between the two terminals if it blows.


  1. This W220 Mercedes just as no power at all and nothing works ,I mean nothing. Any ideas please ..Battery is fully charged no lights no dash lighting nothing . Wont turn over even.

  2. Can anyone tell me where to locate fuse & relay for the engine cooling fan controller unit
    on a S320 W220 1999

  3. 02 CL500 with no instrument cluster, all gauges are locked, no steering wheel button controls, and car will not start. What is the problem? ECU is the fault that comes up. should i replace the instrument cluster to fix the problem. Car still runs fine

  4. CL500…. The Relay for the horn (P) isn’t under the rear seat ‼ It’s in the driver side fuse box ‼

  5. On my 2005 CL600 the F86 fuse is not blown, but the front cigarette lighter socket doesn’t have power. How do you remove it to see if it is connected? I suspect that the lighter was disconnected from the harness and that to get it work would only need to be connected.

    • On mine, the metal piece in the bottom of the cigarette lighter tube was broken. Also, check to see if the metal tabs in the tube are bent too far outwards. If so, use needlenose pliers to bend them back towards one another so that when you insert the cigarette lighter or your car charger there is a good connection between the metals. I ended up getting a whole new ashtray assembly off of eBay since the metal seat in mine was actually broken and shorting it out.

  6. I need to know which relay is for the blower fan under dash

  7. bonjour j’ai une mercedes s320cdi années 09 2002
    mais feu stop reste continuellement allumé ,j’ai changé le contacteur sous la pédale de frein ,c’est pareil
    sa reste allumé que dois-je faire merci

    • Vous pouvez avoir un circuit court ou une unité SAM défectueuse. Connectez votre MB à un scanner de diagnostic avancé.

  8. i am working on a w221 s500 could you tell where the fuel pump control unit is located
