After I got my car back from the dyno - I noticed that the drivers seat stopped moving back and forward.
The memory seat buttons wouldn't make the seat move either.
Then I tested the seat buttons without any weight in the seat - and they worked fine.
Come to find out the wire harness connecting to the seat module had stretched and with weight on it - caused the motor to not get its signal from the module.
Apparently this is a common problem with the C6 - so I ordered a new pigtail harness from Amazon - and pulled the seat out.
Removing the pig tail from the module - I found the wire completely snapped off from the plug. So I cut the plug off - stripped back the wiring.
I soldered in one of the wires and that took forever. I started on the second wire - and my cheap HF soldering iron died.
A quick trip to Lowe's and I bought a real soldering gun - I got the other wire done in like 5 minutes.
I put the seat back in the car - and everything works again!
