Hi again,

 

No - that is the only switch. I just wanted to verify that is what we are working with.

Hi again,

 

Here are the instructions.

 

Stop Lamp Switch Replacement

Removal Procedure

    Caution

    Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

     

  1. Disconnect the negative battery cable.
  2. Disable the SIR. Refer to Disabling the SIR in Supplemental Inflatable Restraints.

getting to the switch is the problem

Hi again,

 

Here are the procedures to disable & enable the SIR system.

 

Disabling the SIR System

  1. Turn the steering wheel so that the vehicle's wheels are pointing straight ahead.
  2. Turn OFF the ignition.
  3. Remove the key from the ignition switch.

    Important

    With the AIR BAG Fuse removed and the ignition switch in the RUN position, The AIR BAG warning lamp illuminates. This is normal operation, and does not indicate an SIR system malfunction.

     

  4. Remove the AIR BAG Fuse from the IP fuse block.

  5. Remove the Connector Position Assurance (CPA) (1) from the driver yellow 2-way connector located at the base of the steering column.
  6. Disconnect the driver yellow 2-way connector (2) located at the base of the steering column.

  7. Remove the Connector Position Assurance (CPA) (2) from the passenger yellow 2-way connector located near the base of the steering column.
  8. Disconnect the passenger yellow 2-way connector (1) located near the base of the steering column.

  6. Install the AIR BAG Fuse to the IP fuse block.
  7. Staying well away from the air bags, turn ON the ignition.
    1. The AIR BAG warning lamp will flash 7 times.
    2. The AIR BAG warning lamp will then turn OFF.
  8. Perform the SIR Diagnostic System Check if the AIR BAG warning lamp does not operate as described.

I hope this helps.

 

Thanks, XXXXX

I know getting in there is hard but it can be done.

 

You might want to remove an insulator panel or two, to get more space.

 

Thanks
