Squeaking, now failed. Where is the fan motor on a B class W245?

[MB-BTurbo]

I have been researching for the last couple of hours as to what could have caused squeaking from my HVAC (which has now failed completely). The car is a 2006 B200 Turbo and believe it may be the fan motor. What I cant find is its location. Is anyone able to point it out please?
Thanks

The fan motor for the interior blowers ?

These are usually up in the passengers footwell , you drop the lower part of the dash to get to them. Usually buried.

Yes, the motor for the internal hvac fans. The Mercedes technician told me it was hidden within the dash but wouldn't go into how to remove the dash or take it any further...I think he wants me to spend £400 getting him to do it.
