Hello Guys,

I just bought my first Mercedes over the weekend (4/16) for $300. It's a 1983 240d has 254,000 miles on it. The pass side rear window doesn't work the previous owner said that they work on a vacuum system? Also the left turn signal doesn't work when I have my lights on and pressing the brake. The green arrow on the cluster lights up very dim and the rear left side light all light up but dim also. And the cigarette lighter doesn't work but that's small and probably really simple. I am new to this so I don't know much about these cars but eager to learn! Thank you for the help in advance.



I didn't find the right solution from the internet.
