Electrical bug - Driver Door - Ideas to find

[bljis123]

Envoy XL SLT with full driver control module, i.e. memory, heated seats... Viper 560X alarm with remote start.

ISSUE:
Driver door control module dead, door lock dead(works manually tho). Just no power to door anymore.

ISSUE HISTORY:
Door controls use to work. Then it was intermittent, yet I could usually do the driver window still. Over time that quit working too. I noticed going from drive to park the door locks would unlock like 5 times in a row. I noticed during this time the driver door lock would no longer lock automatically.

I bought a used control module on ebay used. That would give me driver window only for a while til that went dead as well.

Tearing apart while PCM is in NC getting tuned. Here are some pics, the previous owner had an entertainment console as I see holes left in head panel.

Under Dash, I am guessing this FM modulator controls this wireless thing in back.

Wireless thing in back:

Also, I have this speaker and wireless thingy on driver pillar. It used to give a tone like power on but no connection. Is it a cell phone thing? I just realized I have not heard the speaker humm in a while. hhhmmmm

Any ideas are great!! Posting this just made me think about that speaker on pillar....

Thanks,
Brett

Should be your Onstar box from GM, has all the GPS and other sensors in it.

I am cleaning up wiring that no longer has use and inspecting all wiring and so far nothing looks bad or could have been shorted. Got my PCM back so I am about to test soon... Hopefully it's mysteriously gone...

Finally, I found it!!! Funny thing I tore the whole insides out just to find under kick panel trim on driver side.

Tore all out though unnecessary:

Corrossion on wire and metal area where it was grounding for awhile:

On another note the tune from PCM of NC is awesome and noticeably better!!!!
