A while ago my odometer lights and tail lights quit working at the same time. I tried changing the fuse and it work for a few days and then quit again, this time the fuse isn't broken. They're just not working anymore and I don't know what to do. Suggestions?

If the fuse fixed this and now it is not blown then we may have an issue with the fuse block. Just clarify what fuse you are saying you replaced or found blown and we will have a better idea what the issue could be.

We need to check for power at the fuse which you can just use a test light and check both sides of the fuse.

Here are a couple guides that will help with this:

I assume you replaced the LP Park fuse in the fuse block under the hood?

If that is the case then that brings a couple other things into play which are the head lamp switch and the daytime running module.

Please see the wiring diagram below for more detail on this. Let me know what questions you have and we can go from there. Thanks
