I'm considering buying a new 2007 Cobalt. I rented one recently and liked the car. One thing I noticed is the A/C is somewhat anemic, and the fan speed doesn't seem too powerfull even on high. I didn't notice if there was a Maximum A/C button setting.
Anyone else notice this with their Cobalts?

Good news - there's a button in the HVAC control area that selects "recirculate" as a counter to the default fresh air intake setting and it'll definitely frost yer caboose. (that button has a cabin icon with a horizontal "U" to engage the recirculation mode) I suspect you weren't aware, so the system happily brought in hot/humid outside air which compromised the cooling performance. GM has always done two things right - automatic transmissions (OK - with the exception of Buick "Dynaflow"...) and air conditioning. My better half is also about to take the plunge to an '07 Cobalt to replace her six year old Cavalier. She rented one in July to drive from San Bernardino to Phoenix and marveled at having to advance the heat control a little because it was getting too cold inside the car. And, this was in beautiful downtown Blythe where she stopped for lunch. (114 deg. F. on the bank thermometer across the street)

Max AC is achieved by hitting the "recirculate" button (middle one of three). It keeps cooling the interior air instead of hot outside air.

)) "Max AC is achieved by hitting the "recirculate" button (middle one of three)." ((
 
Thanks for the update. The 2006 Cobalt sales brochure shows the middle button activates the rear glass defogger and the far right button engaging/disengaging cabin air recirculation. I guess that's wrong.

#6 of 16 A/C clutch on startup??? by airmn65

I have a 2006 Cobalt sedan,2.2 eng., automatic...I have heard the A/C compressor, or something, kick in about 10 seconds after start up with the A/C and defroster OFF! Its 70 degrees here, so I have nothing on as far as air circulation. Have any of you heard this same sound of "something" engaging soon after start up? If so, can someone tell me if this is normal? What is it???
    Thanks!

Many new cars are set up so the A/C runs occasionally on its own, to keep the system lubricated and in good operating condition. It usually doesn't run long enough or strong enough to affect your vent temperature, but you might hear it kick in or hear your radiator fan turn on.

Thank you for your info. WOW I never thought of that, or ever heard of that before. Yes my fan also goes on at startup for awhile. Things are really changing with these new cars!! Thanks again micweb!

My recirculate air switch has troubles, It dosn't all ways go on.
Is there something special? Time delay?
