I have replaced this twice in my 08 Impala, after about 3 weeks it starts clicking again!? Could I really be getting this many bad Actuators? Or is there something I don't know? Any help would be greatly appricated!

There are 4 of them, 1 on driver side and 3 on passenger side. They seem to fail very close together time wise. (I just had 2 go out, left and right side not more than 2 weeks apart).

If you're replacing the same actuator over and over you need to have the reputable mechanic take a look for bad linkage or door movement restrictions. Another idea is that GM has replaced their old part number 15844096 with a new one 22754988. The change was not publicised but one can assume the old parts were failing prematurely. Secondly, they are all made in China so I would not expect too much from that. Finally, check that the mechanic is doing a "Re-learn/Sync" with the AC system after the replacement. If not the actuators will begin to work against each other and cause premature failure.

Hope that helps some. Good luck.

What brand of actuator are you buying? Who is installing it?

I had the clicking sound under the dash and the local GM dealer service rep said that it was a AC actuator and they had to remove the dash to repair it and when I asked for a quote they said up to $1200.00. I went to a garage dealing in electronic repairs and they inspected the car and said there were two failed actuators making the clicking sound. I said to fix the car at the quoted price of $800.00. They found that all three of the 22754988 actuators had failed and they replaced all three. The forth actuator 22754989 was working, but they replaced it anyways so I should not have a actuator problem again

I replace my own actuators that I get from the cheapest seller. I refuse to pay the ridiculous prices GM wants for these repairs.

I do like the posting where the driver had the mechanic replace all the actuators in a single repair. It may not be cheaper but it may save some time and aggravation in the long run. If I have to go at it again, that is exactly what I will do.

Over all, this is the only problem I have had with my 09 Impala so I shouldn't gripe but these actuators desperately need a re-engineer job. Thanks Chevy!

The blend door system has raised it's ugly head under my Impala dash. I have been a gear head and tech for over 50 years. I am retired, and I also refuse to pay GM prices for the repair. I have pulled the connection at both passenger side. The other two will chime-in. On the pass side, one duct is cold vent, one is warm. Getting under the pass side is no picnic. Dropping the glove box will give you some room to work. Problem is, the position you will need to get at them sucks.
With just one pass actuator disconnected, cool air out of the ducts. On open / close of any door/trunk... one actuator thumps for approx 20 secs.

Note: This is my idea of a fix... mine. I would like to bring the recir system back on line, but not in my life. I will disable all four of the annoyance and adust my comfort level in the season changes. One of actuators will start up at outside temp changes

I am having the same issues with my '08 Impala. I have replaced the parts about 8 times. Even with the recent changes they made to the parts. They still ho out like clockwork. I got in contact with GM to see if they would at least help with the cost of the repairs or parts. The district specialist is spoke with (Kristen) was very rude. She told me with approximately 172, 000 miles it was time for me to start taking customer responsibility. Itold her that I had been taking rresponsibility for the car, I had replaced the part several times now. She told me that I didn't have the work done a a Chevrolet dealership so they couldn't say if the work was done properly. Its clearly the parts that are failing. She was very rude and was jo help at all. She told me I had to take customer responsibily and get it fixed myself... again! Does anyone have any suggestions?

The blend doors may be 'hung-up'. My '08 Impala will direct warm and cold air out of the ducts. Owners can close off any or all on the dash. My theroy is to get a comfort level out of any duct during summer weather. My plan this eve will be to disconnect all four of the actuators. Select max blue cold setting. The out side ram air open vent will be a constant. {with the fan motor off} The blend may not be in the right church, but I will try to tweek this where it will give desired results.

My problem is I do not have a pet monkey to go under the dash and complete the task. Under the dash is the pew I need to be for this to happen. With the glove box dropped down, this is do-a-ble. ... I am not sure how this is going to play out on the driver side... the ****-pit is some what tight. Will let you know my results and what may or may not take place with blending of cold and warm air. As stated, i will try and tweek this procedure.

Note: My '08 Impala has 180,000 on it. Runs great and looks fantastic. It just has this annoying problem.

I have found that remote-start on a hot day will cause these actuators to cycle several times. Having watched this for a while I can see where the stupidity occurred in the design phase. The computer control kicks in and drives these things to the limits and back with each commencement. As long as the comfort tabs are set at max cool or max heat there will be no stress on the actuators. It's when the levers are set in-between that causes the added stress. I've gotten into the habit of shifting mine to max cool at every shutdown. You'd think this would be settable at the shop but all the answers I received so far has been "no can do".
Another problem is the thin plastic temp control housing that warps and wanes in the hot environment causing the blend doors to jam during the actuator cycling.
Just bad GM juju.
