At night a lot of the radio buttons and equalizer buttons dont light up and the other half do. How do i fix this? Also only half of the LCD screen lights up and the other side(right side) is really dim and you can barely see it.

jump in on https://www.gmforum.com/t281501/ this thread. It is the exact same thing you are trying to do. I will check back in a few days to make sure your question gets answered. If not, I will get something goin for you. p.*- I still have my stock radio. Maybe you can buy it for cheap. I hate stock and will never use it again anyway. Pm me if you are interested.

Well i can take the radio out no problem. But in order to fix the lighting on all the buttons, do i have to replace the whole deck? Or is there a certain fuse or bulbs that need to be replaced?

My 96s tape deck was that way when I bought the car. I put an aftermarket deck in. Didn't even want to mess with it

you will have to take it apart and see which bulbs are burned out, could be easier to replace the deck with one that works, you could check Morad Parts Company - 3800 Motors, Transaxles, & Stock Parts give them a call to see if they have something around

Radio is an easy fix in my opinion, you just need some 40 cent bulbs from offline, and you will need to solder them in. There are a few threads on it if you look around...
