I have this issue a while back and just now had the time to check it out. I removed all the door panels to silicone the speakers and my rear driver side speaker does not work. I switch the two rear speakers to test it and works fine. Does anyone know how do i get this to work? if it is not the speaker then what is it?

 

Try to check the cable that goes to the speaker. When I removed the rear deck to silicone glue my sub I discovered that the sub is not ripped but it wasn't working, so I took it out and checked it with tester and it was dead.
But if you're saying that you checked the speaker, that could be cables.

 

if it is the cables then what can I do? I would have to check the wires from beginning to end and i dont know where to start

 

First start with checking the connection junction of cables. Then go down the cable as far as you can. I think though that the problem is at cable junction.

 

thanks alot man I will do that

 

You are very welcome
