Hi,

There is a rear lamp control module that may be faulty. What color is the wire that has no power? If it is brown, that is likely the ground, so no power would be there. Also, are you certain the bulb is good?

I attached a pic below of the optional schematics based on options. Take a look and let me know which you have and I'll get you the schematics.

Take care,

Joe

Hi,

There is a red/black in the schematics. I followed it and it ran to the rear light control module.

There are three sets of schematics below. I had to cut them in half to make each one readable. The first two are number 2, the next two are number 3, and the last two are number 4 from the list you requested. I wrote numbers 2 and 3 in two of the pics which are numbers 3 and 4 from the ones requested.

Let me know if this helps.

Take care,

Joe
