Do you have cold, cool, cold, cool, A/C?

[austex04 48]

Yes, most of us are convinced, and proven, that the evaporator sensor is part of the problem. I don't want to change anything, and instead have it repaired the way it's supposed to be. If I can't find a competent dealer to replace my sensor for free under warranty, like the repair bulletin from GM instructs to do on all build dates that have the problem, then I will order the $34 sensor and install it myself. I don't want my evaporator to freeze up, and chance damaging the compressor.

The big problem is not being able to get the BCM update since we can't have access to the files or the programming devices.

[whoknew1985 5]

Good evening. Summer days and faulty air conditioning makes for a unhappy camper here. I am happy that there appears to be some work being done on our cars problems. Needless to say, I am still highly irate and losing patience. I have been finding Spark review sights and placing my review of our cars on them. I have been proactive on getting my story out there. Since I have returned from Florida, I have decided to start a Facebook page to start documenting my story and hopefully other people's stories as well. There are not many ways of getting this information out to the general public, but I am trying. If you would like to help, then visit my Facebook page and post your positive and negative comments there. I have called it "Our Chevrolet Spark experience.". Will it do any good? Who knows? At least I hope it will help push General Motors to help us out. Thanks for any help.

Mine supposedly had the bcm update done, but they didn't replace the sensor like the repair calls for, and I still have the problem. The dealer I used now has a history of skipping out of replacing needed parts becouse they don't have them in stock, and calling the job complete, if it's a sensor or a oil filter. At least all I need is the revised sensor, and the repair is complete. And I don't have to saddle up with Mr Goodwrench to get it fixed, LOL.

please anyone with this problem,...reach under your drivers footwell and remove the hvac air temp sensor, tuck it under your center counsel then go for a ride for 10 min or more on max a/c and RECIRCULATE! I almost gaurentee that the cool cold will be gone and you will have to turn down your a/c it will be so damn cold.

if this fixes it you have two options,... leave it like this and enjoy your new ICE COLD A/C,

or re install the sensor and inform the dealer to do the sensor and cam and hope for the best.

it was 92 with high humidity and a heat index of 97 here yesterday and I had 25 degree air coming out my vents....priceless!!!

Yes..I tried that and had some mixed results. While it did at times make it cooler, it also for some reason started to stink quite bad (only started after the sensor was pulled and after the cold spells). Also it seems to produce "fog" from the vent..most of the time (both and fresh air and recirc). Since I don't live in an area with what could be considered very high humidity...not sure what's going on.

You should probably call chevy and start a case, maybe they will send you the sensor so you can change it yourself. At least you can log the complaint about that dealer, not that it does any good.

[psquare75 35]

My 11/12 build 1LT 5spd seems ok at idle, but I'm hardly the best judge, my daily driver Cavalier has a black interior and is NON/AC from the factory, so an ice cube under the seat would seem cool, lol.

However, the girlfriend said it's fine.

Very generic BS.

[Riku89 1]

Hey just an update again so it was 106 here yesterday for alittle bit and I had the AC set on 2 and I stayed nice and cool! Was the 2nd hottest day I had in the car since I had it so for me I am certain it is a fix!

Congratulations on what appears to be a certain fix. I am hoping all of us will be able to say that in our undeterminable future. I am taking my car into the dealership on Saturday for an oil change. This is a different dealership than my local dealership, so I am hoping that I will be more impressed with their service department. I have asked them to look at the air conditioning problem as well, and will hope that something can be done to fix my problem. I purchased my car from this dealership. It will not be a wasted trip as I was told that the dealership is going to pay for the oil change. I will hope for the best and report any news back to this thread.

[WaltK 305]

I had the full "fix" done today, bcm, sensor, and cam. It is overcast and about 80 deg. here today, so I really couldn't stress it, and getting it back kind of late in the day, I can only give you my few observations, hoping tomorrow will be warmer. For openers, it is blowing much colder than before, but at idle the temperature was cool, not as consistently cold as while driving. I now hear an audible click, when I press the a/c button, which I never heard before, and the cooling fan, under the hood, reacts much faster. Keep in mind, this was just a brief ride, of about 7 miles. So I really can't say if it is 100% or not, but I can say it was a marked improvement, I should know more over the next few days, I have an appointment to go back to the dealer on Friday, as they flashed my radio with the "rearview camera" upgrade, if I am not satisfied with the a/c, I will pursue it further. For those interested, the old cam was white, and the old sensor was black. Now just the opposite, black cam, white sensor. I will keep the group informed.

[respdoc 4]

So, to go off my last post and more of an inquiry for others....do most of your A/C's produce condensation almost all the time (without recirc on) ? Again, I brought it up to the dealership and again given the normal story. What makes no sense is my other car doesn't do it.....along with the fact I really don't live in a high humidity area anymore (moved from South Florida). In Fl or other high humidity area's...I guess I might understand it... but here just doesn't seem correct.

Walt,

Did you have to order the parts or did you just show up? Did you have to show them the service bulletin? You also had no other work done prior like mine right.

[WaltK 305]

I went to the dealer last Tuesday to make an appointment to have the radio done. While there, I brought up the a/c, and showed him the printout of the service bulletin, of which I had a copy in my glove compartment, he had no knowledge of this bulletin, which really is no surprise. He asked if he could keep the printout, I complied, and he ordered the two parts. He called me two days later, notifying me that the parts had arrived, and we made an appointment to bring the car in this morning. Up until this morning she was cherry, untouched, same as yours. I was still going to wait, but I felt this is not major engine work, and if nothing else, the car is being upgraded, from some problems the GM geniuses must have run across. So in either case, it can't hurt, and if need be, I can still pursue a permanent fix, jumping off from this point.

I haven't seen any condensation being pushed by my a/c at all. Where is it? Is there an odor? If it's on the windshield, the usual culprit is the heater core.

[Gossamer 50]

Brought Gossamer in for the A/C repair, and they had to order the parts.

Parts are in, now have to find the time to go back.

Since this will be the FIFTH time I've been back for A/C problems (and the dealer is over 50 miles away), I sure hope this is the fix!

[Greg_E 211]

I sure hope Chevy gives you a few free oil changes or something for the 50 miles each way, that's a lot of gasoline to use.

[Gossamer 50]

I got free oil changes for life when I bought the car (although I have to travel 50+ miles to get them), but I'm trying to get them to install the fog lights for free or at least a reduced cost!

[WaltK 305]

I went out for another short ride, this afternoon, temps are 85, it was 105 in the car. I just cruised around the city, 30-35 mph, no hard accelerating. I had the a/c on 3, recirc on, and it was blowing nice and cold, even idling at the red lights, she continued to blow cold, within 15 min, the cabin was at 81deg, and dropping. I didn't hear that audible click, I mentioned in my last post. I still would like to take her out on a blistering hot day, but nothing that bad being forecasted. I still don't want to declare victory, I have been accused of being too picky, although if it behaves like this on a real sweltering day, I will be more than satisfied. If anything changes, I will keep the group posted.

[austex04 48]

I ordered the sensor, it should come within a week. It appears the part was revised at some point, it was noted in the description. The problem is GM already paid for the repair that wasn't complete, and spending $25 for the part is a bargain and worth not going through the hassle with another dealer. I'll never return to the shady dealer I was going to for anything. Mine had the update on the bcm, but not the evaporator sensor, yet. I tried it briefly without the sensor in place, and had to turn it off quickly, because it started blowing fog, that means the evaporator is starting to freeze up. So the bcm update to get it from cycling all the time, and the revised sensor to get it the right temperature, is the fix for 12/12-up build dates.

[Lovgun7 75]

got a call yesterday ofcourse i was working... called right back and no answer ... christ

Via every vent and almost every time when on the "fresh air" setting. Similar to if someone had a small fog machine located inside the dash. I do understand some condensation is normal is really humid climates...but I'm not in one of them...and it has not been excessively humid over multiple days.
