Dash air not working.
2013 Tiffin Red 33aa When the dashboard fan switch is turned on, nothing happens. The buttons for air conditioning and/or recirculating do not light up, showing no indication that they are functioning, which leads me to think it is electrical. There are two fuse style circuit breakers in the outside panel, which have been replaced and still nothing. Any ideas? Should have mentioned that the unit is a Denso product.
