If you have the factory stereo, push in the power button with the stereo on, and then turn it to adjust the balance between left and right. Then you can return it to the normal position. Then PULL out the same knob and when you turn it you will adjust the "fade" between front and rear speakers.

Here is the complete discription of what each wire color does. Please rate this info.

Was the car primarily in a Southern state--no winters? If yes, it could be the wiring harness that leads to the rear wiper/stop light inside the rear tail gate. They usually break at the flex point, and short to the frame.

There is a lot involved in replacing these speakers. You should also know that the original factory speakers are 10 ohm speakers. This means that if you replace them with new speakers (most of which are 4 ohm) you run the risk of damaging the stereo, the speakers, or both. This can also cause a potential fire hazard in your car. If you want new speakers, you really should look at installing a new stereo as well.

To get to the back speakers, you will need to remove 2 bolts located under the front edge of the rear seat (bottom). After you remove the bottom, you will need to remove the rear seat (back). This involves removing the bolts that hold down the rear seat belts, which is a large sized torx bit (T-45, T-47, or T-50... Don't remember which). After removing these, lift straight up on the seat back to remove. Now remove the deck brake light housing, and the bracket that holds it. Now the deck cover can be removed. Be careful not to bend it too much getting it out from under the side trim on both sides.

For the front speakers, you must disassemble a good portion of the dash. Remove the screw holding the light switch and the wiper switch housings. This screw is underneath each housing. Once removed, there are dash mounting screws behind them. These screws (and many of the other dash screws) are a smaller torx-bit (T-10 or T-15, don't remember which). Sometimes they use a 7mm bolt. There is a cover panel just above the glove box. This panel is held on with 2 screws located in the glove box. After removing this panel, you will find 2 or 3 bolts holding on the dash. Last but not least, you will find 2 bolts inside each of the defroster vent grilles. These grilles just snap out for easier access to the bolts.
