Blower switch vacuum leak?

Under heavy throttle the air stops blowing out the front vents and blows out the defrost. Anyone had a similar problem or know what vacuum lines to check and where?

This used to pop up on here all the time. The white vacuum hose under the dash for the recirculate vacuum actuator falls off. Just push it back on. If its on there, you have a leak somewhere in your vacuum supply hoses (possibly a reservoir too, but not likely).

Also.. I had that symptom with leaky brake booster ...
{had written diaphragm, but it must have been the valve because it leaked down with no pedal and boost worked fine}
