If you just want to pick through the array then this may be cleaner
Code:
ForReading1 = 1
Dim i, blnFound

'Create the file system object
Set fso = CreateObject("Scripting.FileSystemObject")

'Initialize a few items
strSource = "F:\Am\EXCEL.CSV"

'Open the source file to read it
Set ts = fso.OpenTextFile(strSource,ForReading1)

'Read the file line by line
Do while not ts.AtEndOfStream
	strLine = ts.ReadLine

	'Remove the quotes from the string	
	strLine = Replace(strLine, Chr(34), "")

	'Split the line on the comma into an array
	strValues = Split(strLine, ",")

	'Check if the dq number matches	
	For i = 17 to 24
		If strValues(i) = dqNumber Then
			'Get the other values you need
			soNumber = strValues(0)
			setNumber = strValues(2)
			sideNumber = strValues(4)
			'Set flag that say the value was found
			blnFound = True
			'Exit the loop
			Exit For
		End If
	Next
	
	If blnFound then Exit Do
Loop

'Close the file
ts.Close
