I need some help. I have a 89 Holiday Rambler class A on a Chevy chassis. My heat/ac fan motor hasbegun to work intermitantly. Typical GM. Mot you give them a good thump when they stop and they work after that. My problem is that I can't locate the motor. I can hear it when it runs and it seems o sound like it is uner dash at the right side. I checked the front end and find a large box cowl that I wold suggest covers the heating and cooling coils but no motor and to take this cowl off involves taking the front end off the MH as well as the cooling and heating pipes. When I look under the dash I can see another box that looks like a distribution box for the heat/cooling ductwork as a half dozen come of this box. I am not sure how hard i is too get at as it seems to me that the entire dash may have to come out before I can access this box. Long and short, any suggestions?
