Left side sound system

I have a 02 TB that appears to have a loose speaker wire on the left side. Is there anything that may help before I start taking the dash off and door panels? Probably a wire from back of radio is disconnected.

It was working before, and if I turn the radio full and balance only to the left there is some sound - just very faint.

Thanks in advance/Bob

I to have a 02 tb with a similar problem. I have lost sound completly from L/R rear as well as very faint sound from the right front door . The left front door seems to have normal sound level. After removing the head unit , I have found no loose or bad wire connections as well as no wire problems from unit to door speakers. Could this be a amp problem or a fuse problem?

If there is SOME sound in the speaker at high volume, that will eliminate wiring problems. Best bet is that the speaker needs to be replaced. Not un-common at all.
