Way down behind the engine on the passenger side for the 3800. Not sure if the same on the 3.4 You can see it but need skinny hands to pull the cap/dipstick. I made a small funnel with a foot or so of small hose on it to top it up. You kind of have to fill it blind and keep checking with the cap/dipstick. Do not overfill. Will usually whine if low.

Add fluid at the power steering pump reservoir. Rear of engine passenger side.
The car should still be under warranty. Take it back to the dealer.
It's built into the power steering reservoir. To replace it you need to replace the whole reservoir. Fortunately, this is an inexpensive part... ($30).
wherr is the resovoir for 2004 BMW power steering fluid
I was looking at a picture in the 2003 Mercury Grand Marquis Owner Guide and it shows the power steering fluid reservoir at the front of the engine compartment between the engine coolant reservoir and the engine air filter box
Top of engine on the passenger side.
The power steering reservoir on this vehicle is found under the hood of the car. It is usually found to the back of the engine, near the firewall, on the driver side of the car.
Probably on the pump itself. From the left side of the car look down below the alternator by the firewall.
Turn the wheel ALL the way to the right and then ALL the way to the left a few times. This will force air out of the lines. Top off the power steering reservoir when you are done.
Thereservoir is located on the passenger's side toward the back of the engine and it's under hoses and pretty hard to see but it's black so you need a long skinny funnel and make sure that no debris gets inside the reservoir
On the passengers side of the car under the hood. There is a black reservoir near the top of the engine nearly center of the aluminum intake manifold, the cap on the reservoir should be labeled "Power Steering Fluid"
there is a small round reservoir on drivers side of engine compartment right below the back of the hood.
