three things seemingly unrelated, but are they?

So i get in my car to leave work about 30 minutes ago and i start it up. First thing i notice is that my tach is not working, i give the dash a little "tap" to see if this will do anything. nothing.

Second i notice that my head unit is not working. I fiddle with it a little bit but to no avail.

third i notice that my engine oil light is on. this is odd because i just changes the oil about 2k miles ago. After getting home i check the oil level and it is in the middle of the optimum range.

none of these things were issues when i got to work, so i dont know what it could be. My guess is a blown fuse but im not sure. Would a blown fuse effect all three of these things? I would check but it is dark out and i cant see that well. Thanks for your help guys.

There is a fuse that controls the stereo and tach. I don't remember which one off the top of my head. I would clean out the oil level sensor with some carb cleaner and let it dry out, sometimes they get junked up.

After Justin and I changed my trunklid and cut the 3rd brakelight, I have been having the same problem. Tach, head unit, OBC aren't working. I am going to figure which fuse it is today, I will post later on tonight when I find the fuse. Unless you do first

I looked at it. Haven't looked at which number it is but there 2 long strips of small fuses. One closest to the motor and one closest to the fender.

Mine was blown in the closest to the fender row. It was one of the 3-7 fuses from the left counting toward the car
