I have a 83' 300SD and it speraticly goes out when it wants to, and it flickers often. They only turn on at random hours, and only last from 5-60 minutes.
I replaced several lightbulbs (back left and right turn signals, and a brake light) and it worked when i put them in, but went out a half hour later.
I also replaced 5 red 5 blue and 5 white fuses, and put them in the most important locatons.
What can be the problem??

Also: My turn signal stalk is not clicking over as it should proceding a turn. Can this be some kind of wiring that wont take alot of work??
I have no manual either

Thank you
