loss of air conditioning and fresh air through vents

[cwg]

While traveling this week, the fan driven vents on the dash went out, losing all air conditioning and even the fresh air. Regardless of the position of the fan speed or function switch, i.e., defrost, vent, or aircond., all air ceased to flow through and the fan did not work. On the other hand, the passenger side controls still functioned. Checked the 25 amp fuse as suggested by Newmar, but it was fine.

Anyone have a similar experience or idea what I will have to have fixed? Thanks in advance.

Not sure you have vacume controlled funtion switch but a vacume hose may have pulled off control. If you see screws around the "perimeter" of bazel that control is mounted on take out screws and bazel will lift off dash and you can gain access to the control unit. DO NOT remove screws that hold the control to bazel.
