electrical problems with AC and radio?!

[gmoneyfosho]

I bought a 1995 240sx SE a few days ago and i have been having a few problems. The car is 100% stock in every way. the factory radio turns on and everything but there is no sound...im assuming a lose wire some where, anyone know any trouble areas i might want to check first? secondly my AC blower will sometimes not work. also not sure if its even a problem, just something i noticed, there has been rediculous amounts of water/condensation while running the AC...like while driving 20 mph there is about 1 drop about 2 inches in diameter every 12 inches or so. if i let the car sit for like 30 seconds there is like a 14-16 inch puddle under the car. not sure if that normal but it seemed like a lot to me.

thanks, kyle
