sounds like something is grounding out, if you can get your hands on another one try swapping them, if not i have a few i could sell you one just message me if you need one
I had the same problem in my first mazda that i had.........I tryed switching the cluster that worked for like 3 days.......then it started happening again......after that i couldn't figure out the problem.......don't no if that helps you or not.........
