hello just a cou[ple of things. First off i have just bought a mercedes clk55 amg and yesterday i noticed none of the interior lights work, or the ones under the doors. I have checked fuses and all seem ok. in the main light cluster there is a wire that is 12v live. im guessing its that whole unit that is faulty, does it control all the interior lights and the ones under the door. Also the heated seats dont work, things i should have checked i know. The switches dont seem to do anything, the leds on them dont light up at all, again fuses ok, any ideas. Thanks in advance for any replies, I am com[pletley new to mercedes and need all the help i can get, Thanks
