Troubleshooting Problem Vacuum becomes weak Solution Inside of the VCX, there is a venturi vacuum generator that may have collected debris during the operation of the unit. If this occurs, the vacuum will become weak resulting in a lower vacuum reading on the System Vacuum gauge and poor performance. Remove the venturi from the line and blow shop air through it. Use the Parts Identification (page 14) to locate the venturi. Reconnect to correct lines when done.
