I just bought this 1995 Chevy Blazer as a first car from my Grandmother's neighbor. And it's been about 3 weeks now and I can not seem to figure out why the radio will not work.
Well the "Radio" works but no sound comes out of the speakers. The time, stations and every button works. My uncle had taken the thing out and everything seems to be connected. But no sound comes out of the speakers. I threw in a tape connected to my mp3 player but still no sound. No even a fizzle or anything.

Is it possible that every single speaker is blown?
Is it a smart idea for me to splice the back speakers and connect them to the subs I have to test it?

Also, Whenever I drive the Gas Gauge moves left and right and I can never tell when its accurate.

Chances are the amp is bad in the radio. Here is how to check to see if the speakers are ok. Take a D-cell battery. Place one speaker wire on the -- and one on the +. Tap the positive wire on and off the battery. You should hear a clicking sound from the speaker. If you do, it should work. If there is no sound, either the speaker is bad or the wire is bad.

As far as the fuel gauge, it sounds like the rheostat in the fuel tank may be going bad. It is a basic electrical resister that sends different levels of power to the gauge to identify how much gas is left in the tank.

Let me know what you find.

Remember, all you will hear is a popping sound. That will indicate that the speaker is connected to the wiring and it is working.

You may also want to try this. I'm not an expert on car stereos, but one of my good friends owns his own business selling, installing. Stereos. What he does to check a stereo is simply place it on his work bench, wire power to it and plug it into a speaker that he knows works. It takes him about 3 to 5 minutes to do it. If there is a stereo shop near you, you may want to try that. If the stereo is bad, now is the time to get to the junk yards. They have so many cash for clunker cars / trucks that parts are going cheap.

Let me know.
