So I opened door, and dash lights came on with the buzzing noise. Forgetting to put my key in the on position, as I was hooking up battery I thought, "I will have to hurry and put key in ignition to stop the strobing, but when I hooked up battery, nothing happened. At break (11:00), the sun was out, melted all the snow, and it was actually warm in the car from the sun, so I hooked battery up and wanted to see if I could figure anything out. They are not bright, but about half way to work (14 min drive) the interiors started strobing slowly and still not getting too bright.ĥ. At the same time, just my regular interior lights are on. The actual heater control face will not light up, and the buttons do nothing. ![]() For the next 2 days, every time I went anywhere, I had to leave my key in the on position so car doesn't strobe.Ĥ.Today, I go to leave for work and it was 30 degrees so I went to turn on heat and heat will not work. My windows are being weird and lights are strobing. Lights wouldn't shut off.Ģ.My electrical problem is happening again, and is not even acting like the first time. My electrical system messed up, then fixed it self in one night. switch goes out, windows doesn't work, on the other hand this problem has been a progressive problem.ġ. Bearing goes out, tire will wear unevenly. Something else might go bad as a result of that being bad, but it's all common sense. Something messes up, it stays messed up, and then it gets fixed. Ok, as a guys that works on anything I can, I am use to the normal process. ![]() There was way more, but you get the idea. For the past 3 days, if my key was not in the on position when the reconnecting battery, the rave would happen. So, I turn key off and the lights just go crazy again. So I pushed the clutch and started it, lights and stuff were still kind of being weird but for the most part everything seemed normal. My head lights, dash lights, every light that was on and maybe more, just started doing the rave and strobing like crazy. At this moment, I realize something is wrong, so I turn my key and engine off. When I was first trying to roll up window, my window was jumping like it was loosing power and getting it back, maybe a 1/4 inch at a time. When I parked at the gas station, I tried to roll up windows and my system just went nuts. For 3 months I never had the problem again, so I couldn't diagnose it.Ĥ days ago, I start car and everything was fine, and then drove to gas station. The next morning, I connect the battery and everything was great. I had to work the next day and it was night time so I jumped it, drove to charge battery and then came home and unplugged the battery. Once I clamped the last clamp to the battery, my taillights came on and when I looked in my car, my dash lights were on keys were in pocket. So, I call a friend to jump me and had my keys in my pocket. OK, 3 months ago, I go to leave and my car is dead. The following steps show you how.I haven't used this account in over 2 years, I don't know how updated my stuff is. You will need to remove the e46 instrument cluster and have it sent off to be professionally repaired. If all of your fuses are intact and your multimeter shows 12 volts at each fuse, then you have an internal circuit board failure in your instrument cluster.We suggest using the hinge guide torx bolt as a ground as shown in the below image. Make sure your multimeter is properly grounded to insure a proper read out of the voltage - poor grounding will give you an incorrect value, or no show no voltage at all. Use a multimeter to check each fuse carrier to verify it is receiving 12 volts of power. The final step for diagnosing your instrument cluster failure is to verify that the fuses are receiving the proper voltage.If all of the fuses are fine, then proceed to the next step to check the power supply. If you find a blown fuse replace it.this may be the cause of your instrument cluster failure. Use a pair of needle nose pliers and pull each fuse to check their condition. The fuses controlling the instrument cluster in BMW E46 3 series vehicles are 10,34 and 43.Turn them both 1/2 turn to release the fuse block. To access them, locate the two white tabs inside the glove box. The fuses that supply current to the instrument cluster are located in the glove box fuse block. It is always good practice to check the fuses and test the power supply to the bmw e46 instrument cluster before sending it off to be repaired.Section 1 - Checking Fuses and Testing Power Supply
