kenney58 Report post Posted July 30, 2015 Just purchased a 2000 Monaco 38A. The front ac is blowing the air out the defrost and not thru the dash vents. Can any body tell me how to correct this problem? Share this post Link to post Share on other sites
wolfe10 Report post Posted July 30, 2015 kenny58, Welcome to the FMCA Forum. You have lost vacuum to the dash HVAC control. The "default" position for the vents is DEFROST. Is this a gas coach (engine supplied vacuum) or diesel (separate electric vacuum pump)? Share this post Link to post Share on other sites
Walt2137 Report post Posted July 30, 2015 Kenny I assume you are talking about a Diplomat but not sure anyway the 12V vacuum gen will be on the firewall in the gen compartment but I would check for a blown fuse in the bay under the driver. Share this post Link to post Share on other sites
kenney58 Report post Posted July 31, 2015 Yes it is a Diplomat, diesel pusher. I will look at it and see is a fuse is blown in the bay area. Share this post Link to post Share on other sites
