Where are the relays located on a Mercedes Benz S420?

SOURCE: s420 radio code

If you call the dealer with your VIN, sometimes they will give you the code over the phone. Some others will need you to bring in the vehicle to make sure you're not dealing with a stolen radio. They sometimes pull the radio out to get the serial number off the radio and can look up the radio code in their system.

I thought they where either on the side of the core support(follow the wire harness and it should go to the relay). If not remove the fuse box lid and then take out the screws retaining the lid housing and you will find a series of relays. There will be one for high speed (engine uses this when temp. is to high) the other is a low speed relay(this is the climate control aux. fan relay) They may have fuses on top of them I know the older models did. I hope I have been helpful.
