Dash air not working properly...

2015 Vista, 35F. Made a stop this morning and everything seemed to be working OK. Starting again, turned on the dash air and no matter the setting, air only blows out of the defrost openings up front. Every setting, same result. Just wondering if anyone else has experienced this on their Winnebago F53 and if you found the solution before I start deeper investigation in the morning. Thank you.

Smile Found and fixed my problem...

The center console on my coach has the typical 7 position switch to choose A/C, Vent/Defrost, etc...

In back of the switch, there is a connector with 6 vacuum lines that connects to the switch. The 6 vacuum lines are each a different color, with 4 of the lines going to the air plenum right behind the center console and 2 of the lines routed through the firewall into the engine bay.

One of the lines going to the air plenum had simply worked its way loose after nearly 5 years and thousands of miles of banging around. Simply reattached the line and back in business.

I have to thank Winnebago service for taking the time on the phone to direct me to where and what to look for. A real sense of accomplishment when you can fix it yourself.
