Sticky dashboard and steering air bag cover when exposed to the sun.

most cars are same, and very hard. no steering wheel pull this time...cool.
the FSM covers it.
the alldata.com does too.
its mounted with security screws on most cars, (headless)
10 steps remove only. and air bags are mech, killers, heed it.

1. Disable the air bag system, as outlined in Section 6 of this manual.
2. Remove the lower panel of the dashboard.
3. Remove the knee bolster.
4. Remove the steering column upper and lower covers.
5. Unplug the connectors from the ignition switch.
6. Remove the steering column mounting nuts.
7. Lower the steering column.
8. Center punch the shear bolts.
9. Use a 3/16" (5mm) drill bit to drill out the heads of the bolts.
10. Remove the shear bolts, then remove the lock cylinder assembly.

not changing AF every 2 years, cause the acid build up.
then eats the core to death, a 1 hr job becomes 8 or more...

how hard, well on a range of 1 to 10 , (depends on skills and tools)
a 5?
taking things apart is easy , getting it all back and working , now that is is challenging.
the thing is , the heater box just dont drop out of the dash in most cars with say 2 screws. (i had 1961 truck that did)

but i open the FSM for your car.
and it shows 37 steps out, and 38 back in
here is the out. (minus photos)
quote (partial) (buy the book buy the FSM and read it.....)

I verify its not a stuck relay...

I disconnect connector under dash and horn stops...

I then suspect its the Horn contacts or a worn grounded wire in air bag/horn switch assembly in steering wheel.

The decorative Vinyl cover shrinks with age...presses on horn contacts against air bag.

I Disconnect Air bag connector (identified as Yellow wire and Connector) usually under dash.

WARNING: ( I Do not - I DO NoT probe the yellow harness/connector with a meter or test light. A test light WILL Detonate my air bag, and impale the bracket in a nearby object/person - me.)

I Removed screws (2) behind steering wheel - which allow air bag horn assembly to be removed.

I Disconnect Air bag connector in this location as well (identified as Yellow wire and Connector) and then;

The red (color varies) and black Horn wires will be plugged into ribbon connectors usually (2) two that feed/connect to contacts for horn function on face of air bag.

I pause here and verify horn will stop blowing when I disconnect the wires going to horn contacts. So I get horn blowing again...

Check horn: To verify this is the cause; I reconnect (whatever fuse/relay/ connector (Not the airbag connector) I disconnected so they will stop blowing) and get horn/s so they are blowing again...

Then I disconnect the ribbon connectors to verify blowing stops.

Note: The experience I had with horn on

Buick Park Ave was at night when temperature cools after hot day, the vinyl cover shrank and horn blows... pressing on horn area of steering wheel firmly would stop horn briefly - then continue.

Note: I will need a rivet tool and rivets... to reassemble.

WARNING: I Do not drill into airbag explosive container. If I do not know how to carefully drill off correct rivet heads and remove vinyl decorative cover from air bag/horn... I STOP and go to the junkyard or ebay and purchase/replace the airbag/horn assembly.

I continued by drilling out rivets (the rivets holding vinyl cover) by using a drill bit as large (or smaller) as the head of rivet and drill gently to release head from rivet body/shank.

I mark all pieces with a magic marker to verify I reassemble right side up (all metal brackets and trim plates and cover).

I Remove vinyl cover exposing horn contact pads which were sandwiched between cover and air bag container.

I used a razor blade to remove vinyl honeycomb material from area of vinyl cover - that when pressed - would activate horn/contacts.

Only a 1/16 of an inch or less needs to be removed.

(I Bend cover inside out and shave material off of area slowly. Care not to cut myself.)

I Reassemble in reverse order with rivets.

Check horn: ...function at this point... by plugging in horn connectors and assure horn contacts work properly as expected.

All cars are a bit different. I suggest you look at a Chilton's Repair Manual available in most large public libraries to get an idea. Air bags are not that easy to deploy by accident unless you get a bit vigorous with tools. Usually the cover just pries off exposing the horn mechanism. The removal of the air bag assembly is best left to experts. I highly recommend the purchase of the Haynes Repair manual for your car; at $27 its well worth the investment. It will provide the technical detail and tools list to be able to do 98% of all repairs. A service technician charges $50-$75 an hour, so the savings alone in the first use of the book will be worth the detailed solution. A new air bag unit costs $350 to $600 depending upon make and model, so it a decision not taken lightly. Sorry I can't provide you more info.

Ignition Switch/Lock Cylinder REMOVAL AND INSTALLATION CAUTION
Some models covered by this manual may be equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS, as described in Section 6. The ignition lock is an integral component of the steering lock mechanism. If the ignition lock must be replaced, perform the following procedure.

I'd say $125.00 is a good price for a steering column.

First, have to remove steering wheel (but I don't have instructions for the steering column. For that, maybe try alldata.com, but that will cost):

STEERING Steering Wheel REMOVAL & INSTALLATION Without Air Bag EXCEPT F-SUPER DUTY STRIPPED CHASSIS MODELS AND MOTOR HOME CHASSIS MODELS Fig. 1: Remove the screws from behind the wheel - F-150 model without air bag
Fig. 2: Pull away the cover with the wiring still connected

Fig. 8: Correct steering wheel installation
NOTE: The factory recommends that the front wheels be set in the straight-ahead position and you paint or make chalk marks on the column and steering wheel hub for alignment purposes during installation. Of these two safeguards, it is more important to mark the column so even if the column is moved slightly, the steering wheel can still be repositioned in its original position.

1. Disconnect the negative battery cable.
2. Remove the one screw from the underside of each steering wheel spoke, and lift the horn switch assembly (steering wheel pad) from the steering wheel. On vehicles equipped with the sport steering wheel option, pry the button cover off with a suitable prytool.
3. Disconnect the horn switch wires at the connector and remove the switch assembly. On trucks equipped with speed control, squeeze the J-clip ground wire terminal firmly and pull it out of the hole in the steering wheel. Don't pull the wire out without squeezing the clip.
4. Remove the horn switch assembly.
5. Remove the steering wheel retaining nut and remove the steering wheel with a puller. WARNING
   Never hammer on the wheel or shaft to remove it! Never use a knock-off type puller.
   
6. Install the steering wheel in the reverse order of removal. Tighten the shaft nut to 40 ft. lbs. (54 Nm)

F-SUPER DUTY STRIPPED CHASSIS MOTOR HOME CHASSIS MODELS

1. Set the front wheel in the straight-ahead position and make chalk marks on the column and steering wheel hub for alignment purposes during installation.
2. Disconnect the negative battery cable.
3. Remove the one screw from the underside of each steering wheel spoke, and lift the horn switch assembly (steering wheel pad) from the steering wheel.
4. Disconnect the horn switch wires at the connector and remove the switch assembly.

With Air Bag Fig. 9: Remove the air bag module and disconnect the wiring harnesses
CAUTION
Read the air bag service precautions in Section 6 prior to doing work involving an air bag equipped steering column component. Always wear safety glasses when servicing an air bag vehicle and handling the air bag to avoid possible injury.

1. Turn the front wheels to the straight-ahead position.
2. Disconnect the battery-to-starter relay cable for at least one minute to let the air bag back-up power supply discharge.
3. Remove the air bag module from the steering wheel (refer to Section 6).
4. Disconnect the horn/speed control wiring from the steering wheel.
5. Remove the steering wheel retaining bolt.
6. Install the Differential Bearing Cone Remover/Replacer, No. T77F-4220B1, or equivalent, and remove the steering wheel. Route the contact assembly harnesses through the steering wheel as it is lifted off of the shaft. To install: NOTE: Make sure the front wheels are still in the straight-ahead position prior to installation.
   
7. Route the air bag sliding contact wiring through the steering wheel at the 3 o'clock position. Position the steering wheel on the shaft an align the marks. Make sure not to pinch the contact wire. WARNING
   Make sure no air gets trapped between the steering wheel and air bag sliding contact.
   
8. Install a new steering wheel retaining bolt, then tighten to 23-33 ft. lbs. (31-45 Nm).
9. Connect the horn/speed control wiring and clip in place. Connect the air bag wire harness. Tighten the module retaining nuts to 35-53 inch lbs. (4-6 Nm). NOTE: When the battery cable has been disconnected, then reconnected, some abnormal driving symptoms may occur for the first 10 miles (16 km) until the PCM re-learns it adaptive strategy.
   
10. Connect the battery to starter cable. Verify the air bag warning indicator light on the instrument panel.

no that will just expose the air bag reemove the plastic covers off the steering wheel that should expose the wiper switch

OK... the very first thing to do is to disconnect the battery for at least 30mins, do not attempt to do this with the battery connected...BOOM! you'll have the airbag go off! when the time has elapsed.. peel back the steering wheel cover to expose the detonation device, carefully remove and this will expose the steering wheel nut! take this off and you will be able to remove the steering wheel. easy job! just be careful.
kind regards

I had the same problem. My 2008 Passat had to get a faulty rotator that controls the electrical part of the dashboard on the car.First the Air Fault light came on then my whole dashboard went out the next day. I had no horn, no radio, no lights on at all on the dashboard. It was that rotator part that controls the electrics. I was told they are faulty after a few months, they ordered a new one, installed and my car is good as new.
