So my car is a 1990, non anniversary. I have the JBL stereo system. I have a problem with some circuit in the car. The previous owner I bought it from said the keyless entry system worked, but the fuse that controls it and some other things blows the instant you turn the car on. Or it pops it up, I can't remember what he said. I think this fuse also controls some other things on the car, like the interior lights (which dont work at all). Im not even sure where this fuse is, it's not under the hood. Also, my JBL system isnt working right. CD's wont play, I put them in and it starts to read them, and the radio switches over to cd, but it spits the cds right back out. Also, the right side is not as loud as the left, and the subwoofer is not outputting anything at all. Due to the crossovers, this makes the system sound really weak and tinny. Is there a connection problem somewhere, or is the sub completely blown?
