Factory Radio Problems

[Dontech]

I have a 2007 NBS factory stereo/CD player. It is not Bose but does have stearing wheel controls and a 3.5mm AUX port in the front. My problem is that now I only have one door speakler ( drivers front ) and the two pillar tweeters working. Every once in a grat while the others will come on but not very often. Any ideas? I think my head unit is dieing.

It's your speakers that are dying, it's typical for GM speakers to fail really early in the vehicle's life, those tweets in the pillars will work forever. You can probably bump or poke the speaker and it'll work again until you turn the radio back off. Most every GM I've ever ridden in that still had stock speakers, there was at least one not working, it's very common on GMs.
