Check the main vacuum connector at the brake booster or the check valve at
the booster. The default position is defrost mode whenever vacuum is lost.

Just noticed today that no matter which button I push on the vent control,
heat only comes from the defroster outlet. I no longer hear the vacuum being
relieved like I used to when I changed the settings, nor do I hear  the
vents opening / closing.

Does anyone know of a common point of failure that might cause this? It
could give me a starting point before I go and troubleshoot each portion in
trying to track down the cause.

Thanks!

Bret
