Chevrolet Impala TSBs/Recalls/Problem Codes



  • quietproquietpro Posts: 702
    Actually, I was asking if anyone else has had TSB Number: 06-01-39-006 performed on their Impala. jcooley reported that his AC automatically switches and stays in recirc whenever the temp dials are turned to the coolest setting. I'm also curious as to whether the AC will remain in recirc after the car has been shut off and restarted. Has anyone else had similar results either with the vehicle new or after having this TSB performed? Thanks! :)

    Yes, the AC stays in recirculate when I start the car now. Since I've had the TSB done I leave it on the coldest setting and its on recirculate all the time. I have a LT1 with 10000 miles now. Its been close to 98 degrees and the AC is working good.

    Thanks, buddy. I took my car in for service today and was told it was up to date. Needless to say, mine is exactly how it's always been. I also wanted the keyless entry fixed since mine only works when I'm within 20 feet. No change there either although they claimed to have found and fixed that problem. I'm going back with specific data in hand. Thanks for sharing that earlier. :)

    i had the tsb done on my ac and it does not do the recirculate mode and i checked the tis and there is no updates that relate to that issue at this time. quitepro what data do you have on keyfob distance issues if any yet becasue you know my only works from about 5 feet!

    The information about the FOB/RKE range issue is called a Preliminary Information. The preliminary information number is PIC4026. It was in a post earlier is the thread. I got the dreaded, "we know exactly what you're talking about" line and trusted them.

    They didn't replace my FOBs but said they were going to reprogram them. I had to bring both of them in and in the process, they mangled my spare key. I'm not at all pleased. I'd say my range is about 25ft at best (it varies) which makes remote starting worthless for me. :(

    THERE IS NEW SOFTWARE PER TIS WHICH should correct all of our other issues with the air condiotioning not working, i suggest we all go back to dealership for this new software part number 15909082, this should do what jcooley says his car does!

    got back from the dealership around noon and had the new sofware put in and i am happy to say that the ac works real good and does exactlly what jcooley says it will do, its almost like having automatic ac now!

    Thanks for the feedback. What did you tell the service rep to do? I got the "let us take care of everything" attitude last visit and nothing was fixed. I'll take the TSB and software part # you mention and see what happens. I have a feeling I'm going to have a fight on my hands and that will be sad. According to them, the software is up to date. Has anyone out there seen documentation on the improved behavior of the AC after the software update? Even with two sources from this forum, I won't have a strong arguing point and I like to go in with indisputable evidence. :)

    quitepro all you should do is tel them with tsb in hand that your car has lousy ac performace at startup and that this latest software flash fixes the issue so that your ac can be like mine and the other guy that had it done. the dealership just wants to make sure you have the issue before they can fix it as usual and i find that if i said i have an issue and come in there armed with information they are usual impressed with my research and are more than happy to do what i tell them, i have never been challenged with an issue except for my brake problem which is something i probably did myself, severe warping during braking above 100 miles per hour, but how oftern do i go above 100, lol. let me know if i can help!

    Next visit will be with the TSB. Last visit I "trusted" them and got typical service. I take it as a lesson learned...that if I ever want warranty service done I'll need to be fully armed with the information.

    They claim to have checked my car and that the latest software was installed. Unfortunately, I have no specifics so I can't be sure they are AWARE of the latest software (like the TSB mentions).

    Thanks again for the feedback. These forums rock!
  • Actually all the impala's do that but for good reason. The full explanation is in the owners manual but the basic reason for this is by bringing air in from the outside (aslo lowering your windows for a minute or two at the same time) the inside temperature will lower faster. The air conditioner takes a little while to cool off and by brining cool air in while driving and then circulating that air the temperature will lower faster. I gave it a try just to be sure I wasn't crazy. I have a hand held thermometer and checked to temperature with and without using outside air first and it cooled off much faster by, bringing in outside air, lowering the windows for 2 minute to get the hot air out, and then circulately. I live in florida by the beach so I think that says a lot

    Thanks...I understand WHY and WHEN to use fresh air. :) I lived in FL before moving to SC and it's even hotter here. My car stays in the garage so it is rarely super-heated by the sun. I would just prefer having the capability to leave my A/C in recirc until I chose otherwise.

    That being the case, has anyone else had the updated software loaded for their HVAC and does it remain in recirc even after restarting the vehicle? Thanks! :)

    i have the latest software and it does work, when the vehicle is turned off it does default to recirc like it should when it is turned back on
  • quietproquietpro Posts: 702
    Thanks, 06fasst. Although I know it's a minor difference, it has been an annoyance of mine.

    Recirculating is recommended because it dries up the air faster, which is more effective in reaching comfort. After all, hand-held thermometers don't have a human skin. ;)
  • Interesting, if this is a maintenance issue, why don't they mention in the manual as a service requirement every 10,000 mile. I have had the shaft greased twice and replaced one time and am still having the same problem again. I love this car, but GM does some stupid thing, such as not replacing a defective part or solving the problem. To claim it's a maintenance issue is why people don't buy GM again.
  • had the car at the dealership for almost 1 full week, in that time had the tsb on the transmission done, replace the tire and rcdlr part replaced and now i am extremely pleased to say i have great range and so far no tire pressure monitor problems, make sure the replace the rcdlr and reprogram with the lates software in TIS or nothing will be fixed!
  • I wasn't aware of a TSB on the transmission. I haven't noticed any problems but what does it address? Also, what is the rcdlr? Is that the receiver for the keyless entry? Remind me...did you have tinted windows?

    Thanks! :)
  • the tsb on the ranny was for some lagging performace on 1-2 shifts, i was noticing more of a studder than a lack of power, the tsb says to replace the 4 clutch piston, the rcdlr is the door lock reciever which is also the tpms as well, and yes i do have tinted windows
  • Cool, thanks. Was there a specific reason they took so long to fix it? Did they give you a rental for the entire time? Glad to hear all is well with your SS. Did you have to tell the tech what to fix or did they figure it out on their own? Sorry for all the questions. Don't feel obligated to answer them. :)
