Ok, I am the proud new owner of a shiny (just washed clay barred and waxed) my 1975 240D. My fuse keeps blowing for my horn, wipers, and blower motor. The horn works when it works, the wipers work on all speeds except for 3, and I think the bower motor runs all the time. Anything I should look for? Also, I had no dash lights, I WANT THEM I replaced a bulb that looked burned out, along with the other ones, as I figured they were close to going out to since they appeared to be original. After this, my fuse blew out for this circuit as well, it also controls the dome lights. What purpose does the little knob on the left side right across from the tripometer reset knob do? Is it a dimmer? Final question, any other diesel benz owners around Rockford, Mi?
