ok, I have a 92 legend cpe and my horn seems to work whenever it wants. If i keep pressing it wont sound then it would for a little bit then no sound again. I checked the fuses and they are not blown what else can it be. I also have a d4 flasing. I heard about the vss but my speedo is not going crazy at all, it works fine. How can I find out the codes and what they stand for. Thanks for the help guys!!
