I primarily write about computer hardware and software on this site however the intention has always been to write articles that assist people in resolving problems. A couple days ago my wifes car, which is a 2001 Honda Civic, started having multiple problems all at the same time. These problems included the air conditioner compressor not kicking on, the power locks not working, the emergency brake light was constantly on, and the dome light no longer came on when the doors were opened however the dome light itself still worked. After a little research I found out that all of these issues combined point to the MCU (Multi-Control Unit) being the problem. The bad part is the MCU is built into the fuse box so below is information on what I had to do to replace the fuse box.
