Interior lights not working after audio install

[Jaferm]

Can anyone give me input on why none of my interior lights are working in my FK8? Interior lights as in vanity lights, map lights, dome lights, trunk lights, and glove box light. Not much has been done to the car. Speakers and amp install from a local professional are the only thing I can think of. Checked fuses and they looked good, possibly may have missed a fuse but I am sure I looked at all relevant ones. Does anyone have any ideas?

Could be one of the following

• Fuse
• Interior Lights Cut Relay
• Wiring
• Body Control Module

You can find the schematics in the following link

Unfortunately the cause is usually a bad install blowing the BCM ($$$$).

I am not educated on this topic enough, but if the BCM is blown wouldn't more things be inoperable? It's just the interior lights which isn't the end of the world but gets annoying at times.

Search the site - the common thread is interior and trunk lights no longer work; most due to messing with the sound system. Perhaps others will chime in when they read the post.

Most likely the fuse or the relay. Or they could have knock some connectors loose too. But just follow the schematic to find the fuse and relay and see if they're still working. That should be your first steps.

Should be under hood fuse A21 https://github.com/JW0914/Wikis/blo... CTR/Electrical/FuseBox/UH Fuse Relay Box.pdf

Not sure where the relay is, but all the schematic should be there in the link I provided.
