Steering wheel removal

you mean turn signal cam replacment
1 disconnect battery 2remove the hub or air bag on steering wheel (center Part of wheel) maybe two screws in the back of steering wheel remove first 3 remove horn button and steering wheel retaining nut then install steering wheel puller 15.99 at autozone. notice the steering wheel angle it only goes back on one way. 4 next shoulb a lock plate there is a retainer ring remove it with a lock plate retainer tool 8.99 use a pair of needle nose to remove ring dont bend out of shape. 5 now you can remove the turn cam two screws on selector and one screw on the hazard light switch then 3 screws on the cam you will need a # 2 and a #1 phillps for these screws. 6 disconnect power cord it probally goes down through column remove the knee plate to see wires by the pedals. 7 thread the new wire harness back down the column with a piece of bailing wire or equalivent. 8 reinstall all in reverse order.

not sure if that has an airbag on horn on 92, but if it does it will say nsrs or airbag, remove screws from back side, if no airbag, IF AIR BAG DISCONNECT BATTERY AND WAIT #) MIN> TO BE SAFE ! then remove horn bag etc: remove snap ring ,remove steering wheel nut, remove steering wheel, next remove snapring and lock plate and wave washer and horn cam keeping them in order of dissasembly, next remove three screws from turn signal switch and remove, if it has cruise control you will have to remove the lower panel under dash and unplug the small wire plug as well as larger plug to steering column and snake wires out of column and snake new ones back in to original position and hook up and put 3 screws back in and assemble column.

dont remove the steering wheel as likely to interfere with the air bag, the turn signal switch may be connected to the wiper switch so have a good look around the two for any connection

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.

Removal & Installataion

1. Verify that the multifunction turn signal lever is in the center of the OFF position.
   
2. Disconnect the negative battery cable.
   
3. Disable the SIR (air bag) system. Refer to the Chassis Electrical Section.
   
4. Remove the air bag module from the steering wheel.
   
5. Remove the steering wheel.
   

Remove the upper and lower steering wheel trim covers using the following procedure.

• Remove the tilt lever assembly.
  
• Remove the two pan head tapping screws from the lower shroud.
  
• Unlock the upper and lower shroud.
  
• Remove the two Torx® head screws from the upper shroud.
  
• Remove the upper shroud.
  

Remove the wire harness straps from the wire harness assembly and detach the wiring harness connectors from the switch side connectors.

Remove the two multifunction turn signal switch screws and remove the multifunction switch assembly from the vehicle.

To install:

1. Install the multifunction switch to the steering column. Use a small flat-blade prytool to compress the electrical contact and move the multifunction turn signal switch into position. Verify that the electrical contact rests on the canceling cam. Install the screws and tighten to 62 inch lbs. (7 Nm).
   
2. Route the wire harness along the steering column jacket assembly and secure into the wire harness strap. Install a new wire tie to the upper tilt head assembly and another lower along the wiring harness, as the original installation.
   
3. Verify that the lever is in the center of the OFF position.
   
4. Install the upper and lower steering column shrouds.
   
5. Route the SIR connector through the steering wheel, align the scribe mark on the steering wheel made at removal, with the slash mark on the steering shaft and install the steering wheel. Install the steering shaft nut and torque to 30 ft. lbs. (41 Nm).
   
6. Install the horn contact leads and the air bag connector to the back of the air bag. Make sure the CPA wedge is in place to secure the connector. Install the air bag by gently pushing on both the right and left sides of the air bag until the retaining springs engage.
   
7. Enable the SIR system by connecting the yellow 2-way connector at the base of the steering column and installing the air bag fuse.
   
8. Connect the negative battery cable. Test the horn, turn signals and headlight operation.
   

There is a plastic piece inside the steering column that will automatically turn the turn signals off when the steering wheel is turned back to 'straight ahead'. This plastic piece can break, and if it does, they can only be turned off manually, as you are doing. I have not worked on anything as new as your cobalt to repair this, but on older cars it involves removing the steering wheel and turn signal assembly. You must also deal with the air bag. Don't attempt this repair unless you have a manual to follow to disarm the air bag and properly remove the steering wheel and other components.

To install:
NOTE Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

CAUTION Be sure that the electrical contact of the turn signal and multifunction switch assembly (2) rests on the turn signal cancel cam assembly.

CAUTION The abrasion sleeve must be installed back onto the steering column wire harness assembly. The ignition lock cylinder case wires and connector must be hanging out of the middle of the abrasion sleeve.

1. To install, reverse removal procedure.
   
2. Tighten the following to specification.
   
   • Top pan head tapping screw: 27 inch lbs. (3 Nm).
     
   • Side pan head tapping screw: 62 inch lbs. (7 Nm).
     

CAUTION When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling . Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

It's unlikely the turn signal switch. Try disconnecting the switch mounted directly above the brake pedal. If the light turns off the problem is in the brake switch. They commonly go bad and can be picked up at a gm dealer for about $15.
