General Information

Vacuum-actuated doors control the airflow through the HVAC module. Outside air is either cooled or heated. The air is then discharged according to the control setting.
You do not have to replace the entire vacuum hose assembly if the vacuum hose leaks or collapses. You can replace the hose by cutting the hose and inserting a plastic connector. If you must replace an entire hose, cut the hose off at the connector. Then attach a new hose directly to the vacuum solenoid control assembly.
