RE: IML: '73 Lebaron - factory installed wrong air door for AutoTemp II - need correct part

["Jim Stacey" <jhrstacey@xxxxxxxxxxxx>]

Thanks Frank for pointing me to the AT2 manual.  All fifty-seven pages of
it!!    I was not aware of it being on the site.  I can't find any reference
or link to it in the REPAIR section of the site under Air Conditioning.
That's where I found the MTSC booklet on ATII. (Maybe a link is there, but I
can't find it. It certainly ought to be.)  The manual combined with Kenyon's
loaner factory tester will be a fantastic resource to club members with
ATII!!!

Thanks again,

Jim,

I have scanned 2 exploded views from my 1972 parts manual that might be of 
help.

You have probably already noticed the AT2 manual on our club site:
http://www.imperialclub.com/Yr/1972/72ATII/Cover.htm

Since ATC was quite common, a used air door should be quite easy to obtain 
from one of our trusted parts guru's: Phil, Bob or Murray.
Btw, getting the fan out is not as difficult as you might think. You just 
have to take the ps-wheel off and remove the plastic mud guard.

Cheers,
Frank
