First off, the car is 1993 SC400 with the Pioneer sound system.

Second, I searched for days and did lots of troubleshooting.

Now I need your help. My passenger speaker/tweeter is the ONLY speakers in the car not working. I switched speakers, didn't do anything. I switched amps, didn't do anything. I plugged the speaker into the driver side door and it worked, so I know it's not the speaker. I haven't tried to cleaning the connectors with an electrical cleaning fluid yet. All I can think is that it's the wiring. But I was hoping that someone knew of a common area to help me figure out a spot to check. Also I checked all the fuses in the driver kick panel.

I just find it very odd that everything involving the audio works fine and all passenger door electronics are working fine except for the speaker.

Any help is greatly appreciated.

I posted this in Audio section, but figured it may be SC specific.

 

sorry, misposted. this was supposed to go in a different forum.

 

Then you got it right the first time. Audio post = Audio forum. That's why we have one.

 

So what do you mean you switched amps? Did you have a second amp you could swap out?

 

yes, i bought one off a used SC and swapped them, same results. everything worked but passenger speaker/tweeter.

 

Smells to me like a cut wire or poor connection. I'd start by checking connections at the amp connector. Then peel your passenger door panel off and check connections into the speaker enclosure. If you have a schematic and know which pins are which, you can disconnect the connectors on BOTH ends - don't leave speakers connected - and stick a 9V battery on the amp end of each wire (connect other end to ground) ad measure the 9V at the door (between wire and ground) for continuity. If you find that you have continuity then something else strange is going on.
Also check that wires have not pulled out of connector terminals, it happens sometimes, esp. if you've had people work on your car.
