    hello hey

    i want to know the instuctions you sent is the the key to start the car on the stering wheel or on the dash in front of the stering wheel

    Expert:  GM Tech (Cam) replied 6 years ago.
    Those instructions are for the key in the dash. There is one picture that is generic for the car line.
    Customer: replied 6 years ago.

    HELLO

    WE STARTED TO WORK ON THE CAR AND WERE ALREADY STUCK.I CAN NOT REMOVE THE TOP OF THE STERING WHEEL WHERE THE EMBLEM IS.WHAT AM I DOING WRONG?PLEASE HELP.

    Expert:  GM Tech (Cam) replied 6 years ago.

    If you are referring to the drivers air bag itself, in the middle of the steering wheel, here is the portion of the instructions I sent you that covered that.

    To remove the inflatable restraint steering wheel module:

  • Rotate the steering wheel one half turn to the right to access the steering wheel inflator module screws.

  • Remove the screws from the back of the steering wheel inflator module using a TORX® driver.
  • Customer: replied 6 years ago.

    WE TOOK OUT THE MODULE SCREWS (2 OF THEM) BUT THE STERING STILL DOES NOT WANT TO COME OUT.WHATS WRONG THAT IT DOES'NT COME OFF

    (THE STERING WHEEL)

    Expert:  GM Tech (Cam) replied 6 years ago.
    You are only pulling gently on the top portion of the pad? The lower portion of the steering wheel trim will stay attached.

    WE ARE DOING AS INSTUCTED BUT WE STILL CAN"T PULL OFF THE RESTRAINT STEERING WHEEL MODULE. ALSO COULD YOU SEND US THAT LAST PICTURE LIKE YOU SENT US THE OTHERS SO WE CAN PRINT IT TO BE ABLE TO SEE IT BETTER THE WAY IT IS NOW IS TO SMALL TO SEE.ALL THE OTHER PICTURES WE WERE ABLE TO PRINT BUT NOT THIS LAST ONE.

     

    DO I HAVE TO PULL THE STEERING WHEEL MODULE OR IS IT SUPPOSE TO COME OUT VERY EASY?

    Expert:  GM Tech (Cam) replied 6 years ago.

    Once you have the screws out, the steering wheel module should just pull off. The screws you removed, were the on the back side and easy to get at, or were they back in the trim and hidden? Also, post the VIN of your car.

    Expert:  GM Tech (Cam) replied 6 years ago.

    Ok. That explains everything. You do not have a classic malibu, yours is the new style. There is a special tool for releasing the air bag. You might be able to use 2 flat blade screwdrivers. Install those 2 screws. Place the steering wheel at 3:00 and place each screwdriver in the slot as shown below. Lift on the screw drives. This system uses a spring and hooks. The blade of the screw driver will catch on the spring and when you pry, if you have it placed correctly, the one end should pop out 1/4 inch or so. Then rotate the steering wheel to the 9:00 and do the same.
