Honda Civic Gauge Lights and Tail Lights not Working | Fix it Guide

This guide explains how to fix your tail lights and gauge lights on your Honda Civic in the event that they have somehow stopped working – usually as a result of a short during the installation of a new stereo head unit. This was done on a 2001 Civic, it will likely work the same on all 2001 to 2005 civics and probably be very similar on older a newer models as well. All instructions are taken at your own risk, be careful – you might want to disconnect the battery while replacing fuses. That said, the is an extremely easy fix that anyone can do themselves, we do not advise you to take your car in for service – that would be a complete waste of money.

It is likely that you are experiencing all of the following problems:

  • Gauge lights behind speedometer and other gauges not working
  • Tail lights not working
  • Main ceiling light does not come on when you open the doors (even in ‘door’ mode)
  • Car does not beep when you leave the headlights on and remove the key
  • Car does not beep when you leave the key in and open the driver door
  • Power locks to not work unless the ignition is turned
  • No constant power to the stereo head unit – the stereo will not store its presets and will not remember the time

The Solution

This problem is very easy to fix – You simply have to replace two fuses in the fuse box under the hood, both of which can be replaced with spare fuses already in your car (so no need to buy anything new.)

The 2 fuses are very poorly named, you would probably never even think to check them to correct the problem at hand. They are the 15A FI ECU Fuse – No. 2 in the chart below, and the 10A Back Up Fuse – No. 9 in the chart below. As you pop them out, have a look at them – you should see that the metal that runs through the plastic is broken (this indicated that the fuse is blown.)

As the chart shows, fuses in slots 21 to 25 are all spares – you will be able to find the 2 replacement fuses you need here (you will have to replace them with fuses of the same amperage, 15A for the FI ECU and 10A for the Back Up.

We would recommend having a look at your Accessory, Radio fuse as well – this fuse is in the fuse box under the steering wheel – post a comment if you would like to see a diagram of this fuse panel and we will put one up.

That’s it! You should be back in business. Let us know if you have any questions.
