trouble areas of 300sd to watch for
Just want to save some other 126 owners some pain.When I lost the plug in to the signal lense,if the wires touch they will fry your signal flasher.Two,the large red and yellow wires coming out of the fuse box get hot and melt together over time.It goes to the glow plugs.I had to pull the wires apart and rewrap with tape.Three there is a replaceable bulb for your fog lamps,about $4.
