Heat/AC temp control / air mix actuator (restricted part?)
 

On my RX-8 I am having a problem with the air mix actuator/temp control. Basically what is happening is the two extremes work (all the way cold, all the way hot), so all of the dealer/Mazda diagnostics come back as "it works correctly". (So I guess I'm lucky that my complaint is my car gets TOO cold w/ the AC on.)

However, if you watch the air mix actuator under the dash it never moves as you move the temp control knob between the extremes (unless you tap it, then sometimes it will move/twitch.)

Anyway, the dealer was able to replicate it after I pointed out the air mix actuator, they worked w/ Mazda tech support to diagnose and order parts. (Unfortunatly they never told me what the part was...)

However, the dealer told me that it may take a few weeks to get in the part. They told me the part was a "restricted" part, and only Mazda themselves could order and ship the part for replacement.

Can anyone explain to me what a "restricted part" is?

Thanx,
Mark

Well, I found out what the "restricted part" was. The "heater control module".

[Note: originally they told me it was the whole radio, apparently the guy who called was mistaken.]

So 'er.. what is a heater control module?

Why?
 

Why would this be a restricted part?

does it maby contain a toxic/controled chemical?
