Description and Operation

HVAC System - Manual

The HVAC system uses three electric actuators to adjust temperature and air distribution.
The actuators are:

* The temperature air mix actuator.
* The mode actuator.
* The air inlet actuator.

The actuators are specifically designed for the right and left side of the heater and the A/C module. When servicing the actuator, ensure that you replace the actuator with the correct service part for the position being serviced.

The reversible DC motor in the actuator operates the valve within the HVAC module.

The actuators are controlled through the inputs from the heater and A/C control.

Air Inlet Actuator

Locations

Under the right side of the instrument panel, right of the blower motor

Under the dash panel, On the HVAC housing near the Blower motor control module

Is there any way to test these or anyway to test the harness to see if you getting a signal. I think mine is bad but i cant tell ive got no heat and the recirculate isnt working

 

[shouldwork]

Hey guys, that's a pretty nice diagram of the blower motor etc. but how can I safely get under the dashboard and remove the fan for replacement, I currently have a fair chunk of my dash disassembled but I can't figure out what the next step is to get at the fan Here's a picture of my current situation

re SHOULDWORK your in the same situation im in but i dont have mine that much apart this is new territory for me im just looking for the last blend door motor i guess i need to dig deeper

 

[2000 LESABRE]

I found the third one yesterday thanks for the pics i only have one bad one im glad its the one easiest to get too

 

[shouldwork]

Ok so, I've pulled back the carpet gotten under the ducting and removed 2 layers of plastic only to find some kind of manifold/possibly the heater core, I have no idea. which has more plastic and no fan in sight

any suggestions?

Rob

SHOULDWORK i was looking at your pictures again the blower motor is in that round housing sticking out of the bottom the best reference point from your pic is where that white paper is hanging in the front
