Thread: Blend Door Actuator Replacement

I have a 04 with the basic system. Does this write up apply? I have no heat, but get a clicking noise when I unlock the car, or its been parked for a while. I think a gear is broken in the Hvac actuator or something.

I have a 2004 Prix GTP...she does NOT have dual climate control. A year ago in the winter, the blower motor went out and we had no heat. We got that fixed and now the blower works very well but now there's no A/C! Today as I was complaining about it since it was only about 104' outside, my son said that on the passenger side, he had cool air blowing out *it wasn't as cool as it should be* whereas I, on the driver side had lukewarm to warm air blowing out. I was told this was a problem with the actuator, which according to what I'm seeing on here, that's more than likely what it is.
My questions are: 1-Is there only ONE actuator for each side of the car or only ONE for the entire car? 2-Is there anyway to be 100% sure that this is what it truly is? 3-Is this something that can easily be done by me?

The last question is due to wanting to save the money and mainly because I've never really had to take my car in anywhere, my husband was always the one to do it. The first time my car was ever taken in elsewhere was for the blower motor. My husband had cancer and wasn't able to do it himself but he passed away on May 1st, a month shy of turning 46 and now he's no longer here to do things like this for me, so if at all possible, to save money, I would prefer to be able to do whatever I can myself. Thanks for any input.
