What exactly is 'automatically climate control'?

Hi all - I am replacing a blower motor resistor ....the parts store is asking if it is 'automatic climate control'. I guess the part says that in the description. The site does say it fits my car ...2010 Chevy Impala LT 3.5. The temp is controlled by slide levers ....it's not digital. Not sure what they mean by automatic climate control. Parts guy couldn't determine that either......hmmmmm. Here is pic of dash controls....if that helps....Any help would be much appreciated!!

You do not have automatic climate control. You have a dual-zone HVAC system.

Any GM dealer can determine the correct part for your car based upon its VIN. Clearly the parts store employee was unable to give you an explanation or determine the correct part.

Good luck.

Thanks! ....I did call and the dealer service guy said he didn't think it was automatic climate control - transferred me to the parts guy - got his voice mail. Will call in morn. I guess I'm glad I didn't try to install the other one with the automatic climate control. I dunno - maybe wouldn't have hurt? .....but maybe! I was gettin some pressure from people - 'well it looks the same - it'll work', .....um, ....not my m.o. lol. Also, I read about alot of installations where the resistor didn't work - or went bad pretty quick. I wonder. .......I'm all about gettin right and movin on.....ha! .....thanks again!

I would imagine, with or without climate control, both units, for the same model year, will use the same fan speed control circuitry.

From a parts sourcing perspective, the design engineers are expected to (re-)use the same parts whenever possible. Both A/C control units need to control a fan, presumably the same fan, hence with the same fan speed control module (aka "resistor").

A simple check is the cable to the speed control unit - if the connector mates up, I'd bet a paycheck that it's the correct unit. Common practice is to use different connectors for different units so that the wrong one can't be hooked up. But sometimes the bean counters will pull rank on the components engineers

Anyway, as long as you're not suffering, it makes good sense to take your time and be sure you have the correct part.
