My running lights work, break lights don't, bulbs are fine, fuses are fine. My center hatch brake light only lights one of three bulbs (the one to far left/driver's side). Changed brake switch, checked all bulbs, fuses and exposed wiring for any breaks. Am unfamiliar with checking current for each wire i.e. which tools and where to test at. What should the next phase of troubleshooting be? Has anyone had this issue?

We are going to need to use a test light or a volt meter. Here are two guides that will help with this:

Also, here is a guide that will help with the testing this repair will require:

Below is the wiring diagram from the manual that will show the detail that we need in order to test these circuits. We need to check power at the bulbs and go backwards from there in order to find out what the issue is.

I suspect this is a TIPM issue as it is not uncommon for it to cause these types of issues.

I attached the process to replace the TIPM as well. Please let us know what you find with this. Thanks
