My hvac is somewhat unresponsive. If I use the defrost or bi-level mode, the engine will not turn off due to lack of vacuum. The high, low,or off modes allow enough vacuum to turn off the engine, Are there CD's available or where can I turn for help? Even when the a/c is on, it does not blow sufficiently to cool the front seat-let alone the back.
