Hello Paul,

• Check that the Balance on your sound system is centered ( in the middle).

• Or Possibly the speakers are NOT connected or Defective.

• Also the stereo may be defective.

Good Luck,
JP

I know of no relay that operates speakers.

Try adjusting the balance or fade, it will be balance for left to right speakers to be adjusted, it may be as simple as this.

After checking the fuses and the relay, I would suggest that you pick up a charging kit for about 25-30 bucks at your nearest dept. store or auto parts store.

probably a broken wire to that speaker or the speaker itself is not working

first> road vibrations can cause cable connections to come loose so you can start by taking out your radio and making sure all of the questions in the back are connected as they should be.
Second> if this doesnt seem to work then the next step is to check the wires going to the speakers that arnt working (this will b quite a job, but if you can do it, it will save u quite a bit of money) .. checking the wires your checking for >bad connection to the speakers >cuts in the wire or if any part of the wire is touchin any other metal object

use a testlight turn on the LS light ground the test light touch the pin inside the lamp socket if it lights look for a bad ground if it does not check your fuses or, run a new power wire under your truck secured with zip ties from the switch

Check for a blown fuse.
