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

Driver Air Mix Actuator

Locations

Under the center left side of the instrument panel, on the left side of the HVAC module

Under the dash panel, On the left side HVAC housing near the top

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

 

[mech29]

MerKava many thanks for the good information,It helped me solve my problem.

 

[2000 LESABRE]

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

Thanks, Merkava

 

[2000 LESABRE]

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

Where is the location of the blend door actuator? I have 2001 lesabre air only blows through windshield and floor today started car and was in auro climate control and was blowing hard through the ven then as I got to about 5-10 mph air went back to windshield and floor

Driver Air Mix Actuator

Locations

Under the center left side of the instrument panel, on the left side of the HVAC module

Under the dash panel, On the left side HVAC housing near the top

Was your problem with heater on, blows hot air on the ps. and a little cold air on the Dr side? Ac works fine.

 

[2005Lesabre]

Thanks for posting this! I have to chase down a constant tapping behind the dash & am suspecting a bad actuator

sounds like the gears inside the ac. has a broken tooth.

 

[mlizotte]

thanks this help to replace my part.

Some comments for those doing the Mode actuator. The first step of course is to remove the plastic panel underneath the dash on the drivers side. That is held on by two screws near the dash itself. I think they are # 8. Once that is removed, slide both front seats all the way back and lay on the floor with your head near the gas/brake pedal. The actuator is as shown and is held in by (3) # 5.5 metric size headed screws. Use a nut driver or something similar. You can use a 1/4 ratchet and socket but that is more cumbersome and the nut driver makes things just so much easier. I also removed the plastic bracket holding the circular timing piece. That was another 4 screws of the same size. I did that to put a little grease in the runners. There are three levers you have to get into time with that circular wheel when you go to put things back together and yes its a little finicky but not terrible.
Test the new actuator before you install it. Its simple, just plug in the pigtail and push the various heat buttons. The actuator should move. If it does not then you have other issues.

This is one of the simpler things I have done lately so its good to get one thing complete. I did test the temp actuator and if you have to change that one its a piece of cake once you remove the glove box panel. Good luck. BTW, the internet adds show the actuators are the same in some places. They are not. There is one for the blend, and one for the mode. They are different but look the same. Prices are vastly different too. Blend one is like $15 and the mode one is $80 depending on where you get them. Again, the ads are not really clear on which one they are selling you! Yikes

Can you explain the circular timing piece and levers that need to be aligned. I have 2000 limited. Also I can turn the lever back and forth, for the install does it have to be to right or left. I am not getting heat. Actuator in glove box moves fine and so does the driver side lower actuator. Trying to understand what actuator moves with what setting. When adjusting this actuator manually still no heat.
