oh ok i get it now thanks for that info. So do you think i have some accuators out in the front and rear?

Like I said, it's weird that you would have multiple actuators going bad at the same time. And I'm not too familiar with the 2003+ electrical system so I'm not really sure about your situation. Let's see if someone more knowledgeable chimes in.

So last night I went to double check what it's doing it looks like hot air comes out of vents but I can't control how high or low I want it . The ac and heat buttons turn on but like I said I can't control anything. That's the latest . Any info on this will be sweet! Thanks

I have a similar issue with mine. No air come out of the 2 rear vents. The 2 controlers do the same thing. I turn it on to 1 and 2 and nothing happens, when I turn it to 3 I only hear a clicking noise somewhere in the rear right side of the vehicle. Can it be that both actuators are bad? where are they exactly located? Any help would be appreciated.
