Ok, kind of a wierd one. I just picked up a 2000 LX. Thought the radio didn't work, then opened the driver door and all of the speakers came on. I looked real quick and didn't notice any crazy wiring, but haven't had a chance to really dig into it. Also the driver window is the only one working. Planning on testing the window wiring tomorrow. Any thoughts on the radio issue?

 

Sounds like maybe the driver door speaker is shorting out causing all the speakers to short. Sounds crazy but had it happen in my old truck

 

This, plus the driver side door wiring is probably bad/corroded. You'll have to inspect before you throw parts at it.
