I agree with you Clare, if I had not taken my caravan to a garage to
verify that the blower was bad I could have used that $77 toward a new
blower motor, which I was able to find online for $59. But I did not
want to be buying parts until I knew for sure it was the motor. And
as busted up from Iraq like I am I can not just install a motor and
then find out that it was not lhe problem so I went to a garage and
paid the money to get it verified. But geting brushes like you
mention and then going through all the hassle of installing them and
then put the motor back in just for it to work for a week or two and
then having to go through all the hassle of taking it out and
replacing it with another motor, you are better off getting a new one.
I was forced after paying the $77 to go to a junk yard and pay $35 for
them to take the motor off for me and it is not guaranteed, just only
can get store credit which is about the same anywhere if the motor
should not work but not sure just how long it will work.

Thanks all.
