Hello, I have a 2008 Chevy Cobalt LS 5 speed manual. A couple months ago the battery completely died and it sat there for a few months. Now with a new battery the car drives great besides the power steering which is only partially functional. The reason I know its partially functional is because when the car is off and battery is disconnected, the wheel is harder to turn compared to when it is started.

Looking under the drivers side dash, it is apparent that the previous owner has messed with the wiring for some reason. However, I have owned the car for 3 years now and only has the problem started after it has sat with a completely dead battery for a few months.

I have checked the 60 amp fuse under the hood as well as the 2 amp fuse on the passenger side fuse box. Both are functional and have even been replaced just for extra measures and assurance. The wiring diagram has been followed and the motor has power, and been replaced. The power steering control module attached to the steering column has power as well. Although this is a part that I am not 100% sure as of yet.

And finally, while replacing the motor and checking wire routing, I have noticed 2 wires that are not connected to any place. A white and yellow wire. When checking voltages for each wire I had 0V and 1.7V respectively. I am not sure as to where these wires connect to because everything seems to have a connection.

Any help would be appreciated enormously, and thank you for all your time in advance. I hope I could be as descriptive as possible. Please find attach some pictures of under the drivers side dash wiring.

Note: when turning the wheel, the headlights dim a little bit, and the idle rpm lowers and raises by a small amount.

Maybe I missed it, but I didn't see what the actual problem was?

Sorry my fault. The question is whether or not these wires affect the power steering? And does anyone know where these wires originally attach to?

from the pictures especially 233905 those wires don't look like factory wiring to me as far as I know GM never used 4 conductor sjo cord to do any wiring - has the car had an alarm system added or remote start maybe? They look like something the previous owner added

I've been having issues with steering as well as it is starting to get really stiff. I suspect it has something to do with the electric power steering motor. I have a 2009 Cobalt LT sedan which I was recently gifted by my dad - any idea if GM is still honoring recalls?

I had an issue with the steering being very hard to turn on my old 09 changed the intermediate steering shaft and it fixed the issue right away. That at about 250,000 km. Are you sure it is electrical involving the motor or could it be resistance because the intermediate shaft "bearings" are shot. Mine when it was removed would not turn at all by hand.... In the car it would not move at all then it would move suddenly but the wheel had to be brought back to center manually.
