OEM Radio works, but no sound
My wife has a 2004 Galant GTS.
The radio has been having "issues" for the past year or so. Some times it doesnt work, turn the car off/on and then it works. The radio looks like it is working. Stations change, cd changer changes cds. However, no sound. Everything is OEM in the car. Since the sound comes out of the speakers sometimes and sometimes it doesnt, I have ruled out a capacitor. I would think if its blown, its blown. No worky at all, but her's works sometimes. The radio is at a point now where it hasnt worked for the past 4 days, so now I have to fix it.
my guesses are the following:
Bad amp
loose connection somewhere
bad ground
Does anyone have any past experiences with similar issues, or any suggestions for what to try.
Thanks!
