Need to know the type of power steering to use

in think its the actuator how do i change it

twice in the last year

The hard buttons on my navigation system work...."soft buttons" ...i.e...the touch screen does not work.

right now its running about 2.5 /3.0..

All the relays are good and none of the fuses are blown but yet I can start the car with a toggle switch that I installed at the relay

a grounding problem, how do I detect the faulty ground?

But as it warms up it slowly gets quiet n you can barely here it unroll you give it gas and Idk what the problem could be an I'd like to know the main cause because I don't wanna sink a lot of money into it...thanks.
