'05 Meridian Dash A/C

[modo]

My first post from MODO.
I purchased a new to me '05 Meridian 34H DP a few months ago. In getting it in shape for a big summer trip I noticed that the dash fan switch never shuts completely off. At the small dot setting a small volume of air continues to exit the dash and floor vents. The Operators Manual states that when the mode control is 'off' the air dampers are closed and the fan is turned off. However, air continues to exit the dash and floor vents. Could this be an electrical or vacuum problem? Any ideas as to fixing the problem.

Modo, I believe this is the dash air conditioning unit installed in your motorhome. You might give them a call and ask for advise.

I'm assuming that this is street air being blown in, not a running fan? There are historical issues with the vacuum lines deteriorating on the dash modulators, all can be accessed from the front hatch. There are a couple of threads about 2 years old complete with pix on what to look for.

See if this helps: Pump noise under the hood??
