noise in front end, sounds like wheel bearings, 110,000 miles, rear end axles and bearings replaced, sounds still present, louder when making left turn when weight of vehicle shifts to front end right side
You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.

how do you remove right rear axle on a 2004 ford crown vic to replace seal on wheel?
Section 05-02A: Axle, Integral Carrier — 8.8-Inch Ring Gear
1994 Town Car, Crown Victoria/Grand Marquis. Workshop Manual
REMOVAL AND INSTALLATION
Axle Shaft
NOTE: Whenever replacing the rear axle lubricant, use Rear Axle Lubricant XY-90-QL (ESP-M2C154-A) or equivalent.
Removal
CAUTION: The rear brake anti-lock sensor must be removed before the axle shafts are removed. The rear brake anti-lock sensor is bolted on the rear disc brake caliper anchor plate.
Installation
NOTE: Check for presence of rear axle shaft o-ring (4A332) on the spline end of the shaft and install if not present.
CAUTION: Care must be taken not to let axle shaft splines damage oil seal or bearing assembly.
NOTE: Axle housing cover must be installed within 15 minutes of application of the silicone rubber or new silicone rubber must be applied.
CAUTION: Make sure machined surfaces on both axle housing cover and rear axle housing are clean before installing the new silicone sealant. Inside of axle must be covered when cleaning the machined surface to prevent axle contamination. Tighten the cover bolts in a crosswise pattern to ensure uniform draw on axle housing cover .
---------------------------------------------------------
Rear Disc Brake Caliper Anchor Plate
CAUTION: Installation of rear wheel bearing or inner wheel bearing oil seal assembly without proper tool may result in an early bearing or seal failure. If inner wheel bearing oil seal becomes cocked in bore during installation, remove it and install a new one.

Lights will time out through battery saver feature only.
The door ajar switch is sold only installed on the door latch.PITA!!
I have tried to clean the door ajar switch on the drivers side door and when I check for voltage I get zero door open and 11 volts door closed.This switch is supposed to break ground to the LCM.Am I correct in checking for voltage?
All the other doors will not turn on the lights when opened nor will the vanity lights come on without opening the drivers side door.
Doors will also not lock when in drive.They lock then unlock.
Thanks in advance.
Don't think you have a door ajar switch problem , more then like the lighting control module is the culprit . Does the door ajar light on the instrument cluster stay lit ?
The interior lighting can be separated into two distinct modes of operation: the courtesy lighting and the demand lighting. The lighting control module (LCM) controls all of the interior lighting in the vehicle, as described in the following text.
The front dome lamps, rear reading lamps, and instrument panel courtesy lamps, can be illuminated either by opening any of the vehicle doors (courtesy lamp function) or by depressing the headlamp switch (demand lamp function).
When any door is open, the door ajar switch grounds an input to the LCM which then sends power to the courtesy lamps. The voltage sent to the courtesy lamps gradually increases from 0 volts to 12 volts within 500 ms (± 50 ms), to achieve the theater lighting effect. When the door(s) are closed the door ajar switch(es) break(s) the ground to the LCM input which then gradually reduces the power from 12 volts to 0 volts within 5 seconds. (± .5 second).
When the headlamp switch is depressed it grounds an input to the LCM which in turn sends 12 volts to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps. When the headlamp switch is depressed a second time, it breaks the ground to the LCM input which then ceases to send power to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps.
The battery saver will disrupt power to the courtesy lamps after 10 minutes, the demand lamps after 30 minutes, and the headlamps after 10 minutes. Turning the ignition switch to the RUN or ACC position will terminate the battery saver feature by disabling the interrupt timers and reinstate power to the lamps.

2004 Crown Vic w/ auto climate control blows only out defrost and floor vents reguardless of setting, how can I get a schematic for the blower doors and such, to trouble shoot?
those control units in the crown vics **** out all of the time. they're not cheap from the dealer, try auto parts stores for aftermarket or junk yards.
one trick we did with cabs was to pull the unit out and splice the black and blue vacuum lines together. that's great for summer, but you have only vent then.

where is the wiper control module on a 2004 crown vic
i believe it is part of the wiper motor which should be located in the driver's side rear corner of the engine bay, on the firewall. Many 03 and up Fords use a "Smart motor" for the wipers which has the motor and a module in one piece.
here is a diagram

99 crown vic wont crank when i turn the key
battery good
Turn key to the run positio, Press on your brake and run your shifter through the gears a couple opf imes then try starting in neutral. This is for the benefit f the neutral safety switch. If still nothing , Raise the hood and and check the battery for a bad or corroded connection. If all is good, make sure car is in park. There is on the driverside fenderwell a relay that looks like a mine Roun With two small terminals and tw large terinals o opposite ides.. When you turn to crank, you put cirrent to one of the small ter minals and that causes the two large battery cables to connect and give power to the starter. If you can jump the battery side cable and the starter side post the starter will crank if nothing is wrong withe the starter.the two large posts. Use a jumper cable,NOT a coat hanger, iF THE STARTER SPINS THEN START IT WITH THE KEY. Good Luck.. Any more help let me know.

for a long time, we would turn on ac and hot air would come out...we would rearrange the temp number to coincide with heat or a.c eventually it would blow cold with ac on and hot with heater on....finally nothing but hot air and it keeps blowing through the floor even in the off position doing diagnostic codes 024 and 051 came up what are these codes related to?
You apparently have a problem with the vacuum doors in the heater/ac unit under the dash. When one of these vac motors fails (won't open and close various flaps), the unit will default to either a defrost setting or floor heat setting. Fixing these is not a do-it yourself job as usually the entire dash has to be pulled to get to the failed parts. Sorry
BTW P024 is exhaust camshaft position timing and 051 is an oxygen sensor error....neither have anything to do with the heater.
