Cab heater not working
2002 Holiday Rambler Ambassador - the front heater blows hot air in the windsheild defrost setting but does not blow in the other settings like chest and floor.... any suggestions at all?

Your vacuum pump is up front on the firewall... probably a Ford diesel PU one. Make sure it's getting power if you cannot hear it running. If running all the time, find the vacuum leak... hose off or hole in the small lines.
