Steering hard to turn

Hi and thanks for using 2CarPros. Com.

If this happened all at once and you have already replaced the pump, I would suspect the power steering oil pressure switch. It is located on the right front of the engine area. I attached a picture of its location to help. You want to locate component P4.

Check to make sure it is not disconnected, have damaged wiring, or a bad connection.

Let me know if this helps or if you have other questions.

Take care,
Joe
