Recently, I removed the centre console of my 1982 240D to clean its years-old sitting dirt .
I do not remember removing any ground wire.

I changed all the bulbs of the centre console lights, including the web bulb for the fibre optic lights. After changing the centre console lights came for a second, then it disappeared and never came back.
Also, the turn signals do not work. I hear rattle sound on the left turn signal only. But, there is no rattle sound and light on the right turn signal.

I would appreciate your help.
