Power steering resevoir?

Did you check fuses and relays first? Diagnose first, then repair. A new motor comes after you connect 12 volts to the old one and see if it works.

This video will explain how to do it.

There are three relays and two fuses that power the radiator fans.
The computer grounds the relays to make the fans come on.
Have you checked the fuses and relays for power ?

They sure will, 97, to 08 have the same footprint for the front seats.

well if u mean its hard to turn then i would suspect its the power steering pump is bad just because its not low on fluid doesnt mean its not bad

YES. the bulb has 2 filaments, and one is bad.

if it is a v-belt set up the alternator power steering pump and maybe the ac can be loosened and they pivot to take the belt off

check power steering motor and wires that may be damaged going to it also check your tie rods to see if they are loose or stripped

The fuel filter is located in the pressure line that runs from the fuel tank to the engine, near to the fuel tank.
Keep the engine off for few hours before replacing the filter, to get rid of some pressure in the lines.

I don't know how much this will help but some common problems with loosing power steering is that your power steering pump is gone.your pump is about a foot below the alternator on the side of the firewall - hard to get to it under the hood without removing some items, I got some prices for you and a new pump couls cost anyware from $18 to $70. also the belt could have loosened up just enough that your power steering wont work. hope this helped.
