My signal lights are not working along with the speedometer. I changed the fuse 2 times already, but it keeps on dying. A few days ago, I had to go pump gas. What shows you how much gas you have, did not go up till today. My car idols when it wants too.
If the fuses keep blowing then you have a short and a pro should fix it. The speedo, may have a bad sensor. You could try clenaing your battery cables as well as the computer doesn't like low power and it will screw up things like you are talking abut.
