So this morning when I went for a drive, I turned my radio on and it wasn't up to par. I used the dial and turned it to left speakers only, there was no sound. The right side speakers work just fine. Has anyone had this problem before, anything that I could do to fix it? My truck is an extended cab if it makes a difference. Any ideas that i could try would be greatly appreciated. Thanks in advance.

Hey Beast, an easy thing to do is have a quick look at the wiring that runs into the door panel. Check the boot for broken wires.
If not that, pull off the door panel and check the speaker itself out.

Just a thought...good luck.

I give it a shot, thanks man.

Put a voltmeter on the speaker connections...a digital one will read something if you are getting a signal. I do not remember what it was though.

Make it easy on yourself. Turn the headlights on without the key in the ignition. If you hear the "ding" then you know it isn't a speaker issue.
