There is someone with a website that tells you this step by step with
picture... In general, you need to take off your wiper blade... pop the
cover underneath that blade... then you can see you blower motor.

*Rise the hood.
*take off the glass rim gaskets from both sides
*unfasten the wiper assembly (4...5 nuts IIRC + connector)
*take off the wiper assembly.
*remove the M8 headed screws that keep the central part of the
firewall at place
*release the blower cover (2 screws)
*pull off the central part of the firewall as far as you can and take
off the blower cover. Be careful
*release the blower wires near the battery
*unscrew three screws from the passenger side of the squirrel wheel
cover and pull out the blower motor sideways. Check the motor, it
could be repairable

PS I do not have AC, so yours can be somewhat different

Hope that helps
