I’ve been having some problems with the power windows on my car. They always go down but sometimes they refuse to go back up again. I started fiddling around with the haywire of cables located under the panel and eventually managed to get the windows to move again but while doing this I also found a very strange black box.
It doesn’t seem like the box was installed by GM. The electrical work can only be described as shoddy as the wires are all tangled up in a bundle and several of them had the insulation cut for no apparent reason.
The black box has “M3U Quasar” written on it along with “Milan – Italy”. There is a terminal block with a lot of wires attached to it along with two positional switches. The purpose of this box remains a mystery.
Here are a couple of poor pictures I took with my cell phone camera.
