Dash blower switch gremlin

[Catpowered]

04 Itasca Meridian
This gremlin is allowing the dash air conditioning/heater blower switch to work on all speeds except high (sometimes). In the past I have discovered that high speed only works when the engine is running, perhaps a voltage thing. Now, this accursed gremlin is not allowing it to work even when the engine is running. When I switched the blower to high, then switched the a/c switch to off and then back to a/c, it worked (on high). Obviously there is something I don't understand. Anybody else experienced this?

Do a search in the Monoco forum "Dash A/C Fan Repair by Diplomat Dave 7/14/2009. I had a simular problem and was an easy fix. Hope this helps !
