Lincoln/Mercury Repair: 93 cougar blend door motor replace, floor registers, heater assembly

Question
Need R&R procedures, hope that the whole dash doesnt have to come out?

Answer
Heck no Len, I won't do you like that! LOL Here's some info for you:

OPERATION
Airflow
The heater assembly is a blend air system that receives outside air through the blower inlet, which is connected directly to an opening in the upper cowl. Outside air is drawn into the system from the cowl, through the blower inlet, into the blower housing. It is forced through and/or around the heater core, mixed, and then discharged through outlets in the discharged air duct to the floor area or through the defroster outlets and/or instrument panel registers, depending upon the type of climate control desired. Several doors determine the amount of air that goes through the heater core and particular outlet(s) through which it discharges.

Off
When the Heater Function Selector Switch is in the OFF position:



The outside-recirc. door is at full vacuum. As a result, no outside air is admitted to the system.
The floor/panel door is at full vacuum, closing off the passages to the windshield outlets and panel registers.
The blend door position may be anywhere within the range of its cable travel from FULL HEAT to FULL COLD.
The Blower Motor is off.
Vent
When the Heater Function Selector Switch is in the VENT position:



The outside-recirc. door, with no vacuum being applied, will block recirc. air and admit outside air.
The floor/panel door is at "no vacuum" to block airflow to the floor registers, and the panel/defrost door is at full vacuum, closing off airflow to the defroster and airflow is directed through the system to the instrument panel registers.
The temperature selector may be adjusted to heat the air, if desired.
The Blower Motor is on.
Floor
When the Heater Function Selector Switch is in the FLOOR position:



The outside-recirc. door is in the "no vacuum" position to block recirc. air and admit outside air.
The floor/panel door is in the full vacuum position, which closes off all but a minimum of airflow to the windshield defrost outlets.
The blend air door position will channel airflow so that a desired temperature level will be activated.
The panel/defrost door is in the "no vacuum" position to block air circulation to the panel registers.
The Blower Motor is on.
Defrost/Floor
When the Heater Function Selector Switch is in the Defrost/floor position:



The outside-recirc. air door and the panel/defrost door are in the "no vacuum" position.
The floor/panel door is in the partial vacuum position, allowing airflow to the floor and defroster outlets.
The Blower Motor is on.
Defrost
When the Heater Function Selector Switch is in the DEFROST position:



The outside-recirc. air door is in the "no vacuum" position to admit outside air.
The floor/panel door is in the "partial vacuum" position and the panel/defrost door is in the "no vacuum" position so that most of the incoming air is directed to the defroster nozzles. There is a slight air bleed to the floor outlets.
The temperature control lever setting will determine the amount of heat being introduced into the airflow.
Blower
With the Ignition Switch in RUN and the Heater Function Selector Switch (on the Heater Control Assembly) in any position except OFF, battery voltage is applied to the Blower Motor. With the Blower Motor Switch in LO, voltage flows through the Blower Motor and all three resistors; in M1, through two resistors; in M2, through one resistor; in HI, through no resistors. With the Heater Function Selector Switch in OFF, the Blower Motor does not run.

Ok, that being said, I have a number of pis that refer to this, but I can't send them in this medium. I will gladly send them off to you if you will shoot me your email addy!
