Hopefully im posting this in the right section...I have a 2010 impala that constantly ticks in several different places now. I was informed that the part is called a actuator and that there was 3 in my vehicle. I have a mechanic willing to install but was wondering are all the actauors in the car the same exact part before I go to autozone and purchase 3 of the same. Thanks for any information it is GREATLY appreciated.

 

no they're not, if I remember right the temp actuators and mode are the same part number but the recirculation one is different, either way I know they aren't all the same part number.

 

My 2010 Chevy Impala is doing the samething I had one of them replaced but it's still doing the samething!!! Guess I should've had all of them changed out
