It started off randomly in wet weather would lose power steering and the instrument panel says service esc power steering. Today I can't even leave my driveway so often. And it's dry weather.
Do you

Hi,

If it isn't working at all, the first thing to check are fuses. There is one in the under-hood fuse box and one in the interior fuse panel. In addition to checking the fuses, confirm there is power to and from them. Here is a link you may find helpful:

I attached the wiring schematic below, so you have a reference for the circuit. If the fuses are good, the next thing to do is scan the can-bus system.

CAN stands for controller area network. Basically, all the different computers/modules are tied together via a few wires. This type of scan will identify codes regardless of the module storing them whereas a traditional scan tool will not. Here is a link that explains how it's done:

If you are able to have that done, it would be very helpful. This could be an electrical issue, a sensor, or even a failing rack and pinion.

Let me know how you would like to proceed.

Take care,

Joe
