I have a 2003 winnebago adventurer, last year everything worked fine, I took it in to get winterized and now that I have it out of storage the fans inside dont work. They dont turn on at all, I tried the AC and you can hear it kick on but no air. Does anyone have any idea what the problem might be. I dont know if when they winterized it if they disconnected something cause I did see that they pulled all my plugs off the water heater, and I dont know why. Am thing maybe they did something else. They wont tell me.they just say bring it in.
