Mercedes Benz repair: Instrument Panel light replacement, 1981 MBZ 380SL, manual supplements, windshield wiper

Question
I was wondering how to go about replacing the instrument cluster lights on my 1981 380SL. There are three separate "clusters" and the far left ( Clock, Tach section is out), on the same electrical note, is there such a thing as a windshield wiper relay? My car's does not work and the fuses are fine.

P.S.  Wanted to thank you for the past advice about my idling issues and your suggestions solved my problem, just wantd to let you know how much i appreciated it!  

Answer
I hope this is enough data to resolve your issues.

Service Manuals act as a detailed guide to the vehicle. They contain descriptions of all important assembly, adjustment and inspections to be performed. Pertinent data, dimensions, and tolerances, as well as special tools for various individual operations are listed in separate tables. Service Manuals also give repair instructions in detailed steps assisted by drawings, photographs and charts. Service Manuals include information on both the engine and the chassis of a specified vehicle. They vary in size from approximately 400 to 1200 pages in length; however, Service Manual Supplements are generally less than 400 pages. Some Service Manuals may also be offered as a CD-ROM.

There are two detailed threads in these forums, but you will need to join, and search around for "instrument cluster".
