Car starts and runs, has head lights but no interior lights radio, or dash. Fuses are good, relays are also good. What else could this be? Thanks

 

What year and model vehicle is this?

 

Sorry its a 2001 Honda Accord

 

Although you mentioned fuses are good. Just to make sure you're aware, there are two interior fuse boxes (drivers side and passenger side).

If you haven't checked the passenger side fuses, then check Fuse No. 10 and 9 on that side.
Driver's side would be Fuse No. 8 to check.

If the above fuses are okay, no dash lights could also be caused by a blown driver's side multiplex control unit. See this video to test or fix without replacing the driver's multiplex control unit (MCU). You will lose the dimmer function if you use this youtube fix. -- If is the MCU, you could find a used replacement too.

 

Hey thank you I figured it out! The 40 amp under the hood got moved by a friend and they didn't realize they put it in the wrong place 🤦🏽‍♀️

 

Glad you figured it out.
