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.

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
