Hi Guys,

I Just wanted to let you know that I was able to fix my rear door speakers, locks, window switches, and also a light under the armrest. I was convinced that I needed a new amp ( speakers), door lock actuators, and swtitches. Turns out there are a wad of wires multi-colored located in the lower B pillar of the car. Most of them were broken! Me and a buddy were able to solder the wires back together, and then use rubber insulators to cover up the patch work. I also replaced both rear window regulators that quit this summer. The soldering took some time and patience but now all speakers, locks, switches, and accesory lights in those rear doors work !

 

Sounds like you are having fun with your GS. They are easy cars to work on.
