So, I bought a 1998 4Runner, and the drivers side front and rear speakers/tweeter dont work. I replaced the deck, with another factory deck. No Dice. Fader/balancer is not to blame. I took the door panel off, and everything is in fact hooked up. What do you think could be the issue? Could they both be blown entirely? not likely without some crackle or something. Passenger side front and rear works.

 

they could definately be blown and make no sound. take the drivers front door panel off and remove the speaker. plug the drivers side speaker into the passenger side plug. if the speaker works then you have found your answer. if the speaker does not work you can always just run your own wires from the doors to the deck.
