Dash Fan Quit Working

[spat]

2002 WH P32 Chassis with no dash fan in any speed. Checked every CB under the hood and inside under the dash and all are O.K. Can anyone relate to this condition? Are there resistors, fuseible links, or relay's I need to be looking for? Also, what is the likehood of the rotary switch going bad in all three positions? Any help would be appreciated. Thank you.

Steve, There's a modular plug on the back of the switch. Although it sounds too simple it happens to me all the time. Try to re-socket the plug a few times to see if it's a connection problem.

This isn't really a Workhorse problem since your coach manufacturer provides all of the heater support equipment and switches.

Hopefully one of the "P" series owners that has experienced this problem may be able to reply. We have many P series owners.

You might have a vacuum line leak. We had some critters chew a line while camping it made everything seem dead including the fan, wouldn't blow any air. On our P32 chassis it was cooked small vacuum lines going to the switch, they were very colorful but did not last long.

I had a simular problem. Do a search for "dash a/c fan repair" by DiplomatDave 7/14/2009. His post is in the Monoco posts.
