Connector Housing Repair Procedure

WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.

The connector housings (available in Digital Radio, Mobile Telephone and Vehicle Locator Antenna Coaxial Cable Kit) are available for 1-way housings, 2-way housings and 3-way housings. Determine the connector housing required:

1-way housing 

No change to the service coaxial cable is necessary in order to install the new coaxial cable into the vehicle.

2-way housing 

A 4-inch jumper is required.

  1. Determine the appropriate generation (1, 2, or 3) and/or size (12.7mm or 8mm) of the 2-way housing that is in the vehicle.
  2. Remove the faulty/damaged coaxial cable from the 2-way connector housing by removing the terminal position assurance (TPA) from the connector housing and then slide the cable out of the connector.
  3. GM2695718

    Install the new service coaxial cable into the vehicle. Use the 4-inch jumper for the appropriate 2-way connector housing to connect the new service coaxial cable to the connector housing.

  4. If the issue is found to be the connector housing and not cable, a new connector housing may be installed while reusing all other components.

3-way housing 

A 4-inch jumper is required.

  1. Determine the appropriate generation (1 or 2) and keyed 3-way connector housing based on the connector housing color.
  2. Note the locations of each of the cables in 3-way housing, as it is important for new cables be placed in the appropriate terminal location in the new connector. The connector housing colors are not interchangeable.
  3. Remove the faulty/damaged coaxial cable from the 3-way connector housing by using a pair of side/diagonal cutters to nip and break away the housing.
  4. GM2695719

    Use caution not to damage the conductive ends of the coaxial cables inside the connector housing. Do not bend or force the terminal out or it could be damaged.

  5. GM2695720

    Install the new service coaxial cable into the vehicle. Use the 4-inch jumper for the appropriate color 3-way connector housing to connect the new service coaxial cable to the new 3-way connector housing.

  6. If the issue is found to be the connector housing and not cable, a new connector housing may be installed while reusing all other components.
