the 2 rear interior courtesy lights do not operate along with the front . I have tried the centre switch which tells me that the lights are in automatic mode yet the back one don't come on. now both of the lights switch on and of manually and both the rear puddle lights work ok. do I need to replace the complete interior front light assembly?
any help???

That's the way the rear lights work, they don't come on with the front, but there are posts on here that show you how to modify the lights by altering the wiring to make them come on with the front lights. 2006 4.2 Supercharged Buckingham blue
