Hey all, i'm hoping someone can help me out here.

I recently realized that both my front and back left side speakers on the driver side of my 2001 VW Jetta don't have any sound coming out of them when i have an auxiliary input hooked up. They work fine with CDs and radio, though.

I had a Sony head unit installed by Circuit City about 1.5 years ago so i would have an AUX input port easily accessible so i could hardwire my iPod, and it's worked fine since they installed it with various iPods and my iPhone, until now.

My iPhone plays out of both earbuds, so I don't think that's the problem.

Does anyone know what might be causing this?

Are you sure your using a stereo wire to plug it in? Look at the headphone plugs on the cable your using, and make sure there are 2 black rings on them.

EDIT: Also make sure your balance is set right obviously.
 
Check your headunit's balance control. Some HU's I've seen have separate audio settings for the various sources (radio, CD, AUX, etc)
 
Also make sure all the connections are tight. Jiggle them around bit, and if the left channel comes back on then one of your cables/adapters is bad.
 
If its working fine on CDs, then its not anything behind the headunit. Check the AUX cable you're using, the phone, and the adapter. If it isn't the balance, the problem almost definitely lies in one of those
 
I'd have to remove the head unit for this, right?

No. By connectors I was referring to where the cable plugs into the iPhone, and the front of the head unit, just jiggle/bend/twist them around, and see if the left channel comes back. If so you have a loose connection, or a bad cable.
 
I checked all the other stuff, i guess it has to be the cable. I'll test another one out tomorrow on my way to work and see if that fixes it.

Thanks
 
Grr...so the second cable does the same thing. It's not the auxiliary cable, and it's not the belkin adaptor.

What else could it be??
 
How does the aux input wire into the head? That's your most likely source. Is this Monsoon?

Yes, this is the monsoon system. I bought a Sony head unit that has an aux in port right in the front of the faceplate... I'm not sure if I'm answering your question correctly though.
