If anyone has had this problem help would be greatly appreciated.2000 4.2 man 4x4 .Just started blowing fuses cannot find any shorts anywhere,tried tocheck the MFS just wiggled the the wiress nothing happened.They seem to blow just randomly,this afternoon on the freeway when I didnt even use them worked when i got on didn't when i got off???.Tried shaking all the connections i could find still nothing I can't get them to blow in my driveway.Any ideas? Thanks

 

You need to identify the fuse(s) by their fuse #. Too hard to guess which one you mean.

it is fuse #13 it controls stop lights and turn signals.I took the MFS swicth apart and cleaned it up a couple of days ago and have not blown any fuses since switch seems to feel a little smoother too,maybe thats all it need.
