I just got a 2005 G6 with the 3.5 V6. So far I need to replace the fog light switch (because the light went out) the third climate control switch (I think the one that controls where the air goes out of because the light is also out) and the power door lock switch on the passenger side (you guessed it... because the light went out). I also need to replace my front passenger speaker, although I will probably replace all of them with aftermarkets (any suggestions on brands? I had Quantum Audio speakers in my old car, but would like to get some that were better than entry level. If you are looking for cheap speakers those are the best for the price... I really liked them anyway).
