Blower Motor 94 S4

[b1biker at aol.com]

 I've developed an intermittent high pitched squeal from my blower fan. I haven't had time to search for the fan and I haven't gotten around to getting a  manual. To busy fixing suspension issues power locks, etc. Can anyone tell me how much of the dash I need to disassemble to reach the fan?

If anyone has a manual that they no longer need for this vehicle I'd be interested in buying it. Please contact me off list.
Thanks in advance to everyone
