I understood you quite well, thats why I suggested what I did. You as a customer, can't be responsible to physically crawl under your coach and inspect the fan when there is something wrong from the factory. That should have been caught at the factory. The shroud could have been attached just a little off center. Who knows, but it certainly isn't up to you to crawl around under there.
Give Terry a call, and tell him Tomcat F15(Rich) told you to call.
PS when you reply, you don't have to start a new topic, just put your currsor on the reply box at the bottom of the last reply.
I normally don't read every topic and just took a chance to see what you ment.
