bluer101 241 Posted August 13, 2013 Share Posted August 13, 2013 I just talked to my resident with the Lemonade LT2. She asked if my Spark makes a high pitched sound every now and then while driving. I said no, she said if she pulls over turns the car off and restarts it goes away. I showed her a video of the high pitch mine produces 10-30 minutes after parking and after the ac has been off. As soon as I played the video she said that's it! While we were talking by our cars her car made the noise while parked and off. But hers only lasted 10 seconds tops. She just got back about 15-20 minutes before this happened. So mine is not the only one with this noise but not while driving. Link to post Share on other sites
Lovgun7 75 Posted August 13, 2013 Share Posted August 13, 2013 maybe its me but ive actually noticed a bit more of an improvement.... its getting cooler now the the point of almost cold... but still spitting of fresh at idle... thankfully its not warm. Now i really dont want the dealership to touch it if its actually improving Link to post Share on other sites
workcar 0 Posted August 16, 2013 Share Posted August 16, 2013 (edited) ok I registered just to respond to this topic... I purchased a 2013 black 1lt manual spark 2 months ago. I had read about the a/c problems before hand but bought anyways. I already have had it to the dealer for repair I handed them a printout of the tech bulletin, they performed the metal check, the evacuate and refill procedure... now heres the kicker.. there was a updated bcm calibration, (body control module) for those not in the gm speak. it was better but not fixed so its going back in on Saturday. THESE CARS HAVE WHAT IS CALLED A VARIABLE DISPLACEMENT A/C COMPRESSOR. basically this means under low load the a/c compressor is designed to become "smaller" or less of a load on the engine. I am now convinced that this is a calibration issue with the bcm and it was done to try to get better mileage from these cars for government mpg mandates, and to compete with other cars in the marketplace this problem all boils down to commanded "duty cycle" of the compressor. duty cycle is a command percentage on a graph type table that dictates how long the compressor clutch stays engaged, and now there is a table for compressor commanded load percentage. now this could be fixed in 5 min by a gm engineer with a laptop, but....the car would loose mpg because it is actually doing what it is supposed to do freeze me out with a/c! also for a refrence my wife bought a 2013 2lt cruze manual 6 speed 2 weeks later and I could freeze a steak if I shoved it in the vent!!! GM... PLEASE LET A QUALIFIED BCM ENGINEER ASSES THIS PROBLEM AND FIX THE CODE! it would save gm thousands of dollars in wasted repairs, and boost sales of 2014 sparks! ok rant off....

WaltK 305 Posted August 16, 2013 Share Posted August 16, 2013 I believe you're right. All these redundant repairs being done with throwing mechanical parts at the problem have resulted in zero, I haven't heard from one satisfied customer. A qualified engineer could probably fix that code in 5 minutes as you say, but their goes their major selling point, MPG's. I think they are trying to find some sort of a balance between a/c efficiency, and mpg numbers, which is not going to be easy. I don't really know what the implications would be, if they came out with a quick fix, ie. great air, lower mpg's, would there be legal implications because we bought these cars rated at higher advertised mpg's? They have to be feeling the heat (no pun intended), not knowing what consequences, if any, they are facing, it is a delicate balance. I am pissed off, but remaining patient, waiting for the right "fix". Link to post Share on other sites

bluer101 241 Posted August 16, 2013 Share Posted August 16, 2013 i dont know about these problems with the euro 2012 version, luckally. It's our stupid government. I have had enough of their crap. Link to post Share on other sites
weetsj 39 Posted August 16, 2013 Share Posted August 16, 2013 errr are we still talking about the A/C problems? XD i haven't reed al the replies my english isn't all that great. i thought is was just about a not working A/C? XD but indeed government sucks. but that go's for everywhere i think. here they f#*#ing want to make everyting again more expensive by raising taxes, give nothing/ save money by stealing it from the poor, and drain out all of our money, while they are enjoying there luxues life.... but that is a different forum XD Link to post Share on other sites
Greg_E 211 Posted August 16, 2013 Share Posted August 16, 2013 The mileage is not calculated with the A/C running, ever. If they did it with the A/C running then there would be a huge impact to all cars. Link to post Share on other sites

sparkfanatic 70 Posted August 16, 2013 Share Posted August 16, 2013 Also if its just a programming issue , it doesn't explain why some Sparks have the issue and others are just fine . Link to post Share on other sites
Lovgun7 75 Posted August 16, 2013 Share Posted August 16, 2013 yeah i didn't expect this to be a fix... although i did email chevy support since its been past well over 24 hours since the "specialist" was suppose to call me i gave them the info provided here and they said they forward it to the proper person ... still waiting ...

Greg_E 211 Posted August 17, 2013 Share Posted August 17, 2013 Nothing from my specialist today either. I did get an email from the general CS people that said it was forwarded to the specialist handling my case so I know they received the message. Link to post Share on other sites

yuwan63755 8 Posted September 2, 2013 Share Posted September 2, 2013 Has anyone heard anything more from Chevrolet Customer Service or Engineering concerning follow up on the a/c problems that many people are experiencing in their spark? Seems there has been no comment since 8/17. I have not experienced this problem in my 2014 and I live in lower desert of California where it is 110 degrees daily. Noticed it a bit on my 2013, but not on the 2014. Obviously someone must be doing something to resolve everyone's issues. Link to post Share on other sites
WaltK 305 Posted September 2, 2013 Share Posted September 2, 2013 Nothing has changed, as far as an effective fix, but the discussion is still active, you can follow it more closely here http://chevysparkforum.com/topic/1038-do-you-have-cold-cool-cold-cool-ac/ Link to post Share on other sites

Obviously someone must be doing something to resolve everyone's issues. nothing new but i was told that if i left my car today the service dept at the dealer would talk to the engineers back east who would give the techs a step by step guide to figure out if my a/c was working properly or not. yeah i dont have time to have my car as a guinea pig for GM so i never called them back and i expect a call today around 2.

Jeffrey Makela 6 Posted September 4, 2013 Share Posted September 4, 2013 I going to the dealer Wednesday to get my mylink fixed. I also told them my ac turns on and off. I wonder what ther going to tell me. The ac seems ok. I had no problems in the 100 degree heat Link to post Share on other sites
Lovgun7 75 Posted September 5, 2013 Share Posted September 5, 2013 (edited) positive update Alright literally got a call about 10 sec ago. here is the run down... of what the dealer manager told me ... they checked the compressor.... working fine. checked for leaks... no leaks... they took it for a tested it out with a thermometer and at idle it was blowing at 71 degrees . Which he admitted was a bit warm. they pulled the freon which he told me should have been at almost a pound (roughly .95) and manager told me the car only had .3 .... after recharging the a/c the temp dropped an extra 20 degrees... now at idle its blowing 51 degrees and while in motion its in the 40s !!!!! THATS more like it he told me he wanted to keep running a few more tests and keep it until tomorrow that way they can check it the next day. i did tell him about the recirculation flap issue and if they could possibly take a look at it. He said he would and that would also contribute to the A/C not working. So its looking good and im happy that they FINALLY admit that its NOT "as good as it gets" if you are going in to the dealer anytime soon for A/C issues heres a list of things you should mention First tell them your issue Warm are at Idle , A/C is not blowing cold when in motion either... print these 2 links out which come from the official GM Techlink documenting the issue... http://sandyblogs.com/techlink/?p=1951 http://sandyblogs.com/techlink/?p=1036 Print this out aswell which is a document given to a member regarding a software update having to do with the A/C gives detailed instructions to the service dealer on what to do to certain build date models https://docs.google.com/file/d/0B6XvlAXN7F5XRXgzcW1NeE1QeW8/edit also Let them know about the Recirculating Flap issue which could also screw up your a/c heres the link with a great video to show the issue http://chevysparkforum.com/topic/988-ac-recirculate-flap/ ask the to check for compressor leaks. As its been universal that the first "fix" is a new compressor hope this helps Edited September 5, 2013 by Lovgun7 Link to post Share on other sites

Jeffrey Makela 6 Posted September 6, 2013 Share Posted September 6, 2013 I went to the dealer to get mylink fixed and they told my ac should cycle every 20 seconds. My ac seems ok. should I just go to walmart and buy a ac charging kit? Link to post Share on other sites

NEGATORY ... if you feel that your A/C isnt cold enough take it to the dealer ... have them look at it and if there is a problem have them put you in a rental... if you think the dealer is gonna say its ok just take it to a different dealer Link to post Share on other sites
Kevin-Gara Brown 0 Posted September 6, 2013 Share Posted September 6, 2013 My AC quit on the way home. I have an 8:30A appointment tomorrow. The service agent admitted that there are known AC issues with the Spark. I hope this gets fixed quick. I really love the car. Link to post Share on other sites
