99' LS front parking lots ok but rear inop.?? I checked the bulbs-ok. Anybody got a wiring diagram for this circuit? seems like it might be a wire/connection that feeds the back taillights...TIA!

 

I had this problem with my 95 z34. I think it was the wire/connection that you are talking about. All the cold and moisture over the years caused some corrosion somewhere there. I'll check my repair records when I get home later.

 

Have you checked fuses? Did both sides go out? Are rear turn signals working or are all rear lights dead?

Bad electrical connection / corrosion at a taillight could be the problem, but that would likely affect one side or the other, not both at the same time.

 

my guess would be fuses if its them all.

 

Hey all, no all the rear light functions still work except for parking/running lights in the rear. The fronts work? Might be a wire somewhere, hence the need for a schematic...My wife was driving it cause the 2 yr old SERTA in our 03 SS just died so off to the dealer it went. this is a spare and she got pulled over because of it..lol...

 

Problem was melted/corroded rear harness connector S400. all set!
