Since I bought my TC the stereo has never worked and I'm now just finally getting around to looking at it. I figured out the head unit didn't work at all so I replaced it with a new model Ford unit. I have power running through the head unit but have no sound. The car has a factory equalizer which doesn't seem to have power. I've used a test light on the plug with the key on to see if I get any kind of popping figuring maybe it's in the wiring. Very, very light static sounds when I did that. Now I'm looking for more troubleshooting methods to figure out why I have no sound. Any ideas?
