Hey guys! I've been struggling with electrical issues in my 2002 Honda Civic LX coupe for about a year. Here's the situation:



- **Lost Power**: Key fobs, dome light, air conditioning, and stereo.

- **What I've Tried**: Replaced all fuses and the multi Plex controller unit.

- **Current State**: Car runs fine, but the electrical issues persist. The stereo only works because I hotwired it to a fuse in the multi Plex controller unit.



I'm looking for advice on what else to check or repair, including any potential relay switches. Any help from fellow Civic enthusiasts and mechanics would be greatly appreciated!

 

Please:
* Check input line/s to fuses & relay/s.
* Check output from there.
* Some common earthing may be culprit.
If possible upload photos and circuit diagram.
Wish you all the best.
regards.
