I have a '94' coupe and was wondering why all panel buttons luminate tangerine except the center console power seat switches. I've had the car for more than two years and these controls have never been lit. I tolerated it because it wasn't a concern, but now i would like to sort this out. I went to the local Chevrolet dealer to acquire new bulbs. The parts employee researched the parts breakdown manual on the shop's computer and said he couldn't find a reference for light bulbs in that area. I find it hard to believe the power seat controls were intended to be completely dark and not illuminated. Does anyone know more about this?
