SQL Query Generates no Data

The code below does not work when I attempt to use a wildcard in the WHERE clause.
The code below does work if I remove the wild card (asterisk).

The code below generates this SQL statement when I include the wildcard.
SELECT * FROM view_eCAP_DATA_EXCEL WHERE WBS LIKE '433*'
and generates this SQL statement when I remove the wild card.
SELECT * FROM view_eCAP_DATA_EXCEL WHERE WBS LIKE '433CA'

Private Sub UpdateQueryTable_BySubsystem(myPath, myFile, myViewName, myDefaultDir, myDestination, myDataSheet, myFieldToFilter)

    On Error GoTo Error_Check

    Dim mySQL As String
    Dim myConnection As Variant
    Dim mySubSystem As String
    Dim cn As Object
    Dim rs As Object
    Dim strFile As String
    Dim strCon As String
    Dim strSQL As String
    Dim s As String
    Dim i As Integer, j As Integer
    Dim ws As Worksheet
    Dim iCols As Integer
    
    ' Path to and file name of Access database
    strFile = myPath & myFile

    mySubSystem = Range("WBSSelect")
    
    ' Set connection string to Access DB
    myConnection = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strFile & ";"
    ' Late binding, so no reference is needed
    Set cn = CreateObject("ADODB.Connection")
    Set rs = CreateObject("ADODB.Recordset")
    ' Open connection to Access DB
    cn.Open myConnection

    ' Build SQL Statement
    If Len(myFieldToFilter) > 1 Then

        mySQL = "SELECT * " & _
              "FROM " & myViewName & " " & _
              "WHERE " & myFieldToFilter & " LIKE '" & mySubSystem & "*' "
    Else
        mySQL = "SELECT * FROM " & myViewName
    End If
   
    Debug.Print mySQL
    
    Sheets(myDataSheet).Select
    Range(myDestination).Select

    rs.Open mySQL, cn, 3, 3
    
    ' Include Column Headers in record set
    Set ws = Worksheets(myDataSheet)
    For iCols = 0 To rs.Fields.count - 1
        ws.Cells(1, iCols + 1).Value = rs.Fields(iCols).Name
    Next

For an ADO recordset, use % for the wildcard with LIKE instead of *:

 mySQL = "SELECT * " & _
              "FROM " & myViewName & " " & _
              "WHERE " & myFieldToFilter & " LIKE '" & mySubSystem & "%' "
