anyone know i can get the wire harness above the headliner. it powers the lights at the mirror and on star.it is no longer made. 2002 Bonneville with sunroof.

junk yard. or depending what part you need you can get new connectors and splice the wires. amazon, rockauto, and some of the online gm parts houses have them

It would surprise me if the wire harness is no longer available since GM'* retention policy is 15 years past end of production, but there is a good chance it is only available as part of a headliner, not as a seperate serviceable item. I agree with Justin'* response. Get one at a junk yard or fix it yourself with wires and connectors as required.

My question is, what'* the issue?

wire shorted out to left visor burned up harness clear to back window.

First thing you need to do is, figure out why that part of the harness burned up. Fix/replace that part, then install new harness.

buick dealer found one at vintage parts. they are no longer furnished from gm.
