Diagnosis - Re: [DML] odd noise!!

["content22207" <brobertson@xxxx>]

Disconnect and cap 3/8" vacuum line from passenger intake rail and see
if noise stops. That is vacuum line to front of car, which includes
power brake assist (be aware before driving car). If noise is vacuum
leak, will need to isolate further between HVAC mode switch or brake
booster. Is also a hard plastic line running from mode switch back to
heater core shut off valve that could be leaking.
