heyyo im a new member to the forums but ive been reading posts here for many months I just now finally decided to create a account since ive been having numerous questions and I honestly need some help anyways as the post title states this post is about interior illumination issues those issues being the rear window switches neither of them illuminate for some reason?? whats even stranger is originally when we first got the car they not only worked but also illuminated nice and bright too so did the drivers door lock (which also stopped illuminating however its still completely functional) anyways one day not too long ago I noticed both window switches had stopped illuminating entirely and at the same time both lost illumination but again they were still entirely functional and even though I found it suspicious both stopped illuminating around the same time I replaced both window switches with brand new original ones hoping this would solve the darkened rear with no nighttime illumination but no the new window switches also do not illuminate so now im lost could it be the BCM causing this or something?? it has to be something electrical cause its really weird how both stopped working at the same time (sorry for the long post I just wanna be as in depth as possible) oh and if you are wondering its a 2010 malibu
