The fuse is in the fuse box inside the vehicle, under the steering column. It is fuse number 13. ALWAYS replace fuses for the SAME amp rate as the one you removed. This fuse is a 10 amp.

heh. good luck.

Open the hood and check the level of the power-steering fluid by removing the power-steering reservoir cap. Add the correct fluid recommended in your owner's manual to bring the level up to the full mark. Be aware that fluid that looks foamy is an indication of air in the system. Replace the cap.
Locate the power-steering bleed valve on top of the steering box near the bottom of the engine bay. Follow the power-steering, high-pressure lines from the power-steering pump to the steering box if you have trouble locating it.
Push a 6-foot length of rubber hose onto the end of the bleed valve. Run the other end of the hose into a drain pan.
Start the engine. Loosen the bleed valve fitting slightly with an adjustable wrench in a counterclockwise direction. Turn the steering wheel all the way to its stop one way and then the other several times. Shut the engine off.
Close the bleed valve by tightening it with an adjustable wrench in a clockwise direction. Remove the power-steering reservoir cap, and add fluid to bring the level up to the full mark.
Observe the power-steering fluid that came out of the rubber hose into the drain pan. Repeat the above procedure if there are air bubbles in the fluid. Close the bleed valve and remove the rubber hose when there are no air bubbles in the fluid expelled from the bleed valve. Close the hood.

There are 2 adjusters on the steering column, One on the left side that tilts the wheel up to make it easier to get in and out, and one on the bottom to adjust for comfort.

yes you do but its easy

There is no no camber or caster adjustment on that model. If the car has been in an accident, chances are something is bent. My experience has been that the shock body and/or the steering knuckle is bent. Parts replacement is the only true fix. If the vehicle has had the ride height altered, ie. lowering springs, then there are adjustable upper control arms and ball joints available. These do generally only address the camber angle, not caster, which can also greatly affect handling. hope this helps.
