Winnebago Coach Heater Fan

We have a 2004 35U Adventure
On the dash there is a row of switches one is a coach heater switch with high/low it was a very handy heater when going west in late November
last yr the heater fan came on slow and making some noise then quickly got quite.
I was testing it the other day and when I turned the switch on the fan made a loud grinding noise (like a cat going thru a fan) then shut off.
Sounds like it was coming from under the dog house but I cant seem to locate it, any ideas how to get to it?
Thanks in advance for any help.

On mine it is under the floor just behind the dog house. If your water heater is ahead of the door and behind the front tires just open the compartment door and look in there. If you are over 95 lbs. you won't get in far enough to do anything.

Mine is a 2000 Adventurer.

We have a 2001 35U on a Workhorse chassis. I was able to replace our fan without completely removing the water heater. I did pull it out as far as I could without disconnecting the engine coolant hoses. I also removed the partition between the water heater and the cargo bay. On ours the water pump is mounted on that partion. A little bit of a struggle, but I didn't want to disconnect the coolant hoses.

When I bought my Winnebago Solei New from Dealership the Front blower for AC and heat made a noise. took it back to Dealership and there tech and reps. would say that is how it's suppose to sound anyway took dash apart and had to order blower motor assembly repaired my self. no sound when I replaced it I can tell you Winnebago is not the quality they should be. I have had a lot of Problems with my coach and would not recommend Winnebago to anyone...

After investigating the coach heater fan replacement I decided to not do it because I need to remove the water heater, so I will just wait till the water heater fails which im sure it will sooner or later.
Thanks for the advice given.
