This switch dose it all. I have the covers off the column, it looks to me like the air bag needs to be removed from the steering wheel and the wheel removed. I could use some assistance on how to do this, or a manual that I could buy to help me.

Re: Turn signal,hazard lights switch bad.
I worked at a salvage yard for a while. During that time I pulled hundreds of airbags. I thought I'd share a few things.
I've provided this as a supplement to erietracks solution, not to replace it. It provides important additional information you need to be aware of when working on or around SIR (Supplemental Individual Restraint) airbag systems. It lists the potential dangers of doing so and the appropriate precautions against accidental premature deployment. Any work done on the steering column should include this.
Precautions for working with and handling airbags: Take these Seriously!!!
Alway wear safety glasses.
Control the environment - no kids, pets, people horsing around.
Disconnect the negative battery terminal. After you
are done, make sure no one is inside the vehicle when you reconnect the
battery. If your vehicle has an anti-theft system, you'll need to get
your activation codes to reset your sound system.
Do not use solvents to clean your airbags. They may ignite if accidentally deployed. Use only a damp cloth.
Airbags are sensitive to heat in excess of 190 degrees F. Store them accordingly.
Airbags are sensitive to impact - handle them carefully
Airbags are sensitive to static electricity - ground
yourself, Spray the seat and rug with fabric softener (anti-static -
ever heard the term 'static cling')
Wires for the SIR are bright yellow, the connectors are labeled.
In addition to forward mounted sensors, there are also three sensors in the dash.
Do not use voltage testers or VOM's on SIR wiring.
Do not haphazardly disconnect airbag components
Disable the system:
Turn the wheel to the straight ahead position
Lock the ignition and remove the key
Disconnect the negative battery cable. Be advised, this alone will not render the system safe. The diagnostic module (DERM) can retain a charge
Remove the airbag fuse (refer to fuse block cover for location)
At the bottom of the steering column locate the Airbag connector. (Yellow wire, yellow conduit)
You may need to remove the sound insulator panel beneath the instruments to access it
Disconnect the plug
The system is now disabled. That does not mean you can let your guard down. It means that you can now continue working around the system with a higher degree of safety. Continue to observe all safety precautions. Airbags should be handled with caution at all times.
REMOVE THE AIR BAG BY 1ST DISCONNECTING THE YELLOW WIRE HARNESS LOCATED UNDERDASH & REMOVING SIR FUSE. USING A SMALL PHILIPPS SCREWDRIVER /PUNCH OR DRILL BIT, INSERT INTO SMALL HOLE LOCATED IN REAR OF AIR BAG. YOU WILL PUSH ON AN INTERNAL RELEASE MECHANISM. AIR BAG WILL POP OUT SLIGHTLY WHEN MECHANISM IS RELEASED. PULL BAG TOWARD YOU & DISCONNECT WIRING HARNESS. REMOVED UPPER & LOWER COLUMN TRIM COVERS & THEN STEERING WHEEL. THERE IS A SPECIAL PULLER NEEDED TO REMOVE WHEEL AFTER YOU REMOVE THE RETAINING NUT.THE MUTLI-FUNCTION SWITCH WILL THEN BE

Re: Turn signal,hazard lights switch bad.
You can go about this in 2 ways.
1. Disconnect the battery. Pull the airbag fuse. Remove the airbag by taking out the torx bolts on the back side of the steering wheel. Disconnect the wires for the airbag and horn. Remove the steering wheel retaining nut. Use any standard steering wheel puller to remove the wheel. Then change your multifunction switch. Reassemble in reverse order.
2. This is the fast way. :) You'll notice that there are 2 or 3 t-15 torx or 7mm bolt holding the switch in place. One on top and either 1 or 2 facing the backside of the steering wheel. It's ease to get the top bolt out. The fronts can be tricky. What I like to do is take a small torx bit (not a socket) and clamp it in a pair or small vise grips. Turn the steering wheel to get as much clearance as possible. Then use your bit setup to turn the bolt out a little at a time. After youget it out a little way you should be able to finnish removing it with your fingers. Somethimes a 7mm 1/4" drive socket will work as well. Because of the smooth surface you will have to clamp it very tight.
Once you get the hang of it, the second method should take about 10 minutes to change the swith out. Either way will work well. Let me know if you need anymore help, Len

First try toggling the hazard switch a few times. Sometimes it gets stuck. If no go and all associated fuses are ok, I would look at directional switch. Very common on these.if you're not mechanical inclined this could be a bit more than you may be able to handle. Diagnosis consists of removing steering column cover and checking for power at switch, but caution has to be taken because air bag system wiring also is in that area, you don't want to probe wrong wire.
Models from 98 on use a combination flasher. This flasher is mounted either on the front or on the back of the junction block. The
combination flasher is a smart relay that functions as both the turn
signal system and the hazard warning system flasher. It is designed to
handle factory-fitted equipment. If aftermarket equipment is added to
this circuit (such as trailers with lights), the flasher will
automatically try to compensate to keep the flashing rate the same.
The flasher contains sophisticated internal circuitry that cannot
be tested with conventional equipment. Substituting a new unit for a
suspected defective version is the easiest test.
On air bag-e quipped vehicles, disconnect the battery negative
cable(s) and wait two minutes from the air bag capacitor to discharge.
Remove the junction block cover. If the flasher is accessible, grasp and pull the flasher from the fuse panel.
If the flasher is not mounted on the outside of the junction
block, remove the steering column cover from the instrument panel. Reach
through the opening to access the fuse block on the back of junction
block. Pull off the flasher.
Inspect the socket for corrosion or any other signs of a bad contact.
Install a new flasher in the connector.
Install the fuse panel cover.

Fig. Early style flasher system: dual flashers mounted on junction
(fuse) block. The turn signal flasher is the lower of the two; hazard
flasher is the higher one
You may have a bad connection on the Plug-in connectors at the Turn signal switch. What you will need to do is remove the plastic steering column cover and expose the Turn signal switch. The switch itself is called a MFS which means multifunctionswitch. Everything for the turn signals and wipers goes through this unit. On some models you have to remove the Ignition tumbler or even drop the steering column.
You may need to tighten the MFS to the column. There are several small female Torx bolts holding it tight. OR the connectors are loose on the wiring loom at the switch OR there is a broken wire which separates when the column moves. Be careful when uncoupling the connectors because you do not want to break the mounting tangs.
When you lose the turn signals, try engaging the Hazard button and see what works. Most likey nothing will, but in the Hazard mode you will be able to perform a wiggle test and once you find the bad connection in this mode everything should work when you get out of Hazard.
On Deville and Fleetwood, remove the left lower sound insulator. On Eldorado and Seville, remove the left side sound insulator.
Remove the Connector Position Assurance (CPA) and detach the yellow 2-way connector at the base of the steering column.
Remove the steering wheel.
Make sure the ignition switch is in the LOCK position to prevent the SIR coil assembly from going off-center.
Remove the SIR coil assembly retaining ring and the coil assembly. Allow the coil to hang freely.
WARNING The SIR coil assembly will become off-center if the steering column is separated from the steering gear and is allowed to rotate or if the centering spring is pushed down, letting the hub rotate while the coil is removed from the column.
Remove the wave washer.
Use tool J-23653-C or equivalents, to depress the shaft lock, then remove and discard the shaft lock retaining ring.
Remove the shaft lock.
Remove the turn signal canceling cam assembly.
Remove the upper bearing spring, upper bearing inner race seat and inner race.
Move the turn signal switch to the RIGHT TURN position.
On Deville, Fleetwood, and 1990 Eldorado, and Seville, remove the multi-function turn signal lever as follows:
Make sure the lever is in the OFF position.
Remove the access cover from the steering column housing.
Detach the cruise control wiring connector. Note the position of the connector when installed in the column.
Pull the lever straight out of the turn signal switch.
On Eldorado and Seville, remove the multi-function turn signal lever as follows:
On 1992-93 vehicles, slide the connector cover toward the front of the vehicle.
Unplug the electrical connector. On 1991 vehicles, note the position of the connector when installed in the column.
Push the lever straight in, rotate clockwise 1?4 turn and pull the lever out of the switch.
On Deville, Fleetwood, and Eldorado and Seville, remove the screw, button, spring, and hazard warning switch knob.
On Deville and Fleetwood, remove the one signal switch arm retaining screw. On Eldorado and Seville, remove the 2 signal switch arm retaining screws. Remove the signal switch arm.
Remove the turn signal switch retaining screws.
Remove the wiring protector and detach the turn signal switch connector.
Gently pull the wire harness through the column and remove the turn signal switch.
This problem sounds like it could be one of two things. It's possible that you have a bad Lighting control Module (LCM) or a dirty, worn or faulty turn signal switch.
Is a microprocessor based module that controls several vehicle subsystems.
Responds to electrical input signals from various switches, sensors and external modules.
Is located on the LH side of the instrument panel.
Subsystem functions include:
Headlamps with auto lamps.
Turn signal lamps/hazard flasher lamps.
Daytime running lamps (DRL) .
Interfaces with the Driver Door Module (DDM) for illuminated entry and anti-theft systems.
A scan tool can be used to diagnose if this is the problem. Turn the ignition switch to the "On" position and set the front wheels to point straight ahead.
Turn the ignition to the on position, (Don not Start) And straighten the wheels. Make sure all the accessories are off and place the ignition in the OFF position. Now locate the Restraint Control Module fuse in the fuse box and remove it with a pair or needle nose pliers or a fuse puller. Once removed turn you ignition to the On Position and look to see if the Air bag light stay lit, if it goes out you have removed the wrong fuse. Now under the hood, remove the ground (negative cable from the battery) and wait at least 2 minutes for the power to diminish from all circuits.
Replacing the multi-function (Turn signal) switch is fairly simple. The steering column cover needs to be removed first. It is in two halves, top and bottom, and the screws are accessible through the bottom. There should be four of them - Philips head, recessed about 2".
To make it easier to separate the two haves once the screws are removed, it helps to have the tilt-wheel dropped to a horizontal or slightly downward position.
Once the cover has been removed, ( If air bag equipped) You will need to remove the air bag using a socket and ratchet, lift the bag slightly to reveal the electrical connections and remove and mark them for ease of installation. You will now need to remove the signal arm by unscrewing it. You might find that you will need to use a piece or rubber and vise grips. It's tight, and the rubber, rapped around the switch arm is there to protect the finish when using the vise grips. You'll see the mounting for the switch and the wiring harness connectors. The replacement should be fairly obvious at this point. There should be another four screws/bolts that hold the multi-function switch assembly to the column (two on top, two on bottom.
WARNING THIS IS A VERY DANGEROUS JOB IF THIS IS YOUR FIRST TIME WORKING ON CAR. BECAUSE YOU ARE REMOVING AND HANDLING A AIR BAG. YOU HAVE TO DISARM AIR BAGS YOUR STEERING WHEEL HAS A AIR BAG IN IT. YOU HAVE TO TURN OFF RADIO TO KEEP FROM LOSING RADIO PLAYING CODE THEN YOU DISCONNECT NEGATIVE BATTERY FOR 15 TO 20 MINUTES TO DISCHARGE AIR BAGS. TURN SIGNAL SWITCH AND HAZARD SWITCH IS IN THE STEERING COLUMN.YOU NEED A HAYNES REPAIR MANUAL.WITH PHOTOS AND INSTRUCTION SHOWING HOW TO REMOVE STEERING WHEEL.YOU NEED SPECIAL TOOLS LIKE STEERING WHEEL PULLER AND SNAP RING PLIERS.
The problem is most likely the turn signal switch located in the steering column, tough to replace without the proper experience and specialized tools. The air bag and steering wheel need to be removed to replace the switch.
You have a bad multifunction switch.It is not hard to replace just remove the bottom cover on steering column and top should raise up enough to get to the 2 screws holding the switch on.If you can not get enough clearance with top cover on then you will have to remove lock cylinder to get it off.Just turn key to on postion then look under the lock cylinder part of steering column and you will see a small hole.Stick a small screw driver or pic into the hole and push the pin then remove lock cylinder.
