Ac actuator (2 Viewers)

[Operationlc100]

Need some help. Have an 06 with built in nav. My hvac isn't switching. I was going to replace blend door actuator. Can someone tell me the location? Online I've seen it on drivers side, passenger side behind glove box and was told I need to remove whole dash. Also I replaced the blower motor with a Napa replacement. The Napa cage is a little smaller. Does that matter? Thanks for help.

Bump. Still looking for insight

So what do you mean when you say "HVAC isn't switching" Then you replaced blower motor and now you're thinking about repairing blend door?
>> Is your heat and AC working normally, but you just aren't able to switch the mode from feet, to head, to defrost?

• Blower motor - Pushes air ( I'm not sure if the cage being smaller is an issue. if it fits and mounts up and the blower can spin then its probably fine?
• Blend door - Controls flow of air
• Your post was for " AC Actuator " - I'm not good with AC and I don't know what this is

>>> Sorry I may be mistaken.... I did a Google and it talks about how the blend door controls hot / cold air so may be best to ignore me

I couldn't find much info on it either, the thread below might have some helpful troubleshooting tips

I have full heat only regardless of what temp adjustment knob is on and regardless of whether AC is turned on or not. I also have hot air coming through the vents when fan is turned off but fresh air is selected. It stops when I turn recirculating air switch on. I have already had the console knob checked (and replaced microswitches) and I cleaned the temp sensor under the ignition and made sure the hose was connected. (I think that would only matter if set to Auto but I checked it anyway.) Most problems I read about seem to be weak or not heat but mine is obviously the opposite. If...

There are three servo motors that actuate three blend doors. 1. is for hot/cold temp adjustment, 2. is for location of air exiting, either upper vents, lower vents or combination of the two, and 3. is for recirculate or fresh air entry into the cabin.
