Hello everyone. New to The forum. Excited to see all the enthusiasts. I have a 1999 SL500 convertible. I had to change out the entire push button replacement center console unit. Found the part was able to get it in easily. Problem that I'm having is it needs a code to be programmed into the unit. Since the car is so old. I have not found anyone outside a Mercedes dealer. That knows what to do here.?? If anyone can help me with this it would be greatly appreciated as this is my mother's car. I am trying to get it fixed for her. It is over a hundred degrees where I live. And the air conditioning keeps going on and off. Because this code has not been programmed into the new unit. Also the old unit that I had taken out. They want a code to be put into that unit? But with no explanation of where to get the code? I am really desperate for help at this point. She cannot drive the car because of the extreme heat and her age. I have already paid the mechanic to do the job. But he is telling me his computer does not know what to do? So I'm very frustrated and upset. I just want to get the car fixed from my mom who is 78. Thank you in advance to anyone that could help us out. Can someone please help here? I can't believe no one has this information?? I really need the help she cannot drive the car in the extreme heat here. And I just need to know a simple code. Can someone please help me out?? Or am I in the wrong section?
