In mid July My 2 front center vents stopped blowing any air. About 2 weeks later the began to blow air again. And then they stopped after about 10 days. Any idea what is causing this?

Not sure since it being intermittent. Originally thought the blend doors or actuator but now Im not sure. Any suggestions would be appreciated.

Thanks

Obvious question...has it been set to blow out those vents that entire time? On Auto it can automatically move the air to defrost or feet if that's what it determines is best for the current conditions to hit your temperature set point.
