air cond/ heat pump fan/blower question

[oops!]

hi all......i dont usaually post in this forum.....as i just cant seem to get out of the dry dock.....

i have a dometic heat pump/air conditioner....well...its a long story......but the thing went swimming in the salt chuck.

i want to replace the computer board and the fan/blower.

all of the parts guides just have the whole unit......is there any inside tracks to the parts for it?

cheers....
