Stereo display not working and charging ports not working Sign In

2008 Pontiac Grand Prix/ 3.5L V6/ ~172,000 miles

Hi,

I recently purchased my Pontiac and i've been doing work on it to fix a lot of things on it, it has a rebuilt title.

My first problem is with the stereo display. The display doesn't light up when the car is turned on, even when the radio is on and playing. My girlfriend once got half of the screen to turn on by tapping it but i haven't been able to turn it back on since. I assume its some kind of loose wire, the rest of the radio works fine.

My other problem is with the charging ports/cigarette lighters. I have one on the outside of the console and another on the inside. I inserted my charging cable into each one but neither of them began to charge my phone. The car was on when I attempted to use it.

I don't really know what's wrong with either or how I would go about fixing the problems so any instructions or advice would be appreciated.

Thanks!

The back lighting bulbs are probably burnt out. You can actually repair that, but it requires removing and dismantling the radio.

Check the AUX PWR Fuse 25 amp in the fuse block under the hood.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

If part of the display came on by tapping, chances are there may be bad solder connections inside of the radio.
