I had an issue with my compass mirror literally "blanking out". Well, it wasn't a blank out, but more on the line of the LED elements not getting enough power to show in daylight or even at night. In near pitch darkness, you could make out the elements of the LED display showing up. The first thing you should do is check the fuse and wires supplying power to the mirror. If after 3 times this method does not work, you truly have a dead mirror display or a dead fuse. Replace all covers, caps, and reinstall the mirror.
So, I figured I'd try a trick from the BMW side of the world, in which doing a similar method would resurrect dead pixels in their LCD display on the driver's information center (in the gauge cluster).
Note - this worked on my particular mirror, which is the stock compass mirror for a 97.5 truck. I have no idea as to when AMG quit using this particular mirror. It is a very common mirror, mimicing the GM compass mirror used in that same era. This trick may work for other compass mirrors of similar type and function.
- 1 Can of Electronics Component cleaner. ($3 at Auto Zone). DO NOT GET THE VERSION THAT LUBRICATES AND CLEANS!
- Tons of rags
- A small slotted screwdriver
- A Penny (Not kidding here!)
- Ignition keys

Replace all covers, caps, and reinstall the mirror.
