When the TB is idling the A/C is not cold, heck, its not even cool. Even when the car has been in the garage and is relatively cool, its not until we get down the street that we feel some of the chilly willy. :thumbs: To be honest, its like the compressor isn't even running. However, when on the road, it's one of the best A/C's I've felt. Does anyone elses do the same thing?

Yep, mine does the exact same and it doesn't really seem right. Its not too fun when its 90 out and you have to put your kid in the car seat and the air just keeps blowing hot air till you drive for a while. Once I get some time I'll take it to the dealer.

 

One other thing I noticed is that if you have your a/c set on recirculation, and once it starts blowing cool air, you and turn the a/c off and it keeps blowing cold air.

go3, thanks for the input. I have even tried shutting the rear air off and see what happens... still a bit warm for me. Mine hasn't been back to the dealer yet. Its a 2004 with less than 2500 miles. Ours are exactly the same though. EXT, LS, 5.3. I'm afraid when I take it back to the dealer, it may be worse than when I took it in. :thumbs:

SGI, thanks for your input too. Maybe it has something to do with the Mason-Dixon line that Scott and I live closer too. :thumbs: Seiously, are your temps and humidity like they are here in my area?

It gets warm and sticky here in norther ky, upper 80 low 90's with the same humidity.

 

I love the v8, glad it didn't get v6, I think I would have been a little dissappointed with the power, the v8 flys

There is a TSB for this, I am trying to get the TSB #. It is a computer program issue.

That would be awesome. I wondered if something was keeping the compressor from running. When you get the TSB, whats my next step? Can the dealer make the neccasary changes to the ecm? Thanks! :thumbs:

      Anyone had to replace their Onstar module a.k.a. Telematics unit?

      Hasn't come up in the 3 gm forums I follow. And only gm knows the frequency of failure of that part. LMG, you want a recall so it's replaced for free...

      Transmission Woes :-(

      You need a better code reader/scanner.  You are missing codes.  Did the dealer give you a copy of the SAVI scan from that visit?     If the fluid hasn't been changed, change it.  Shudder will likely go away.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By newdude · Posted

      TLDR to my other post...   Hard. Pass.  Too many what ifs.     Are you set on a 3.0 Duramax?  Have you considered anything not GM just in case?  If you don't have to have a pickup, lots of other options for $27,000 out there.

      I see some red flags.   - No mention in the Carfax if the oil pump belt was changed.  LM2s had a 150,000mi service interval, and its got 164,245mi on it.  So right out the gate it needs about $3000-3500 for that to be done before driving it another 150,000mi.  Belt is at the rear of the engine.     - If something happens to the transmission valve body, the special coverage is expired by mileage.  That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time.   - 2020 LM2s seem to need timing chains after 80,000mi at some point.  They fixed this end of 2020/starting 2021 model year engines.  They will usually set a P0016 I think?  There is another $8000-10,000 if it needs a chain.  The main chain is at the back, secondary at the front so the pump belt would be done at the same time if it needed chains.     - Long oil change intervals.  7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM.  Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all.     - Long fuel filter changes, again likely taking the fuel filter life to 0% or more.  First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi.  So counting its original fuel filter, its had only 4 fuel filters on it.  No bueno IMO.         Good news?    - It has had only two warranty trips to the dealer.  The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax).     - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc.         The "emissions system checked" could just be how something was flagged for Carfax.  GM dealers have to do SAVI reports for warranty repair orders so they scan the truck.  So its possible that is there for that?

      Thank you, @Z45!   NOTE - No all repair shop/Dealers reports to Carfax   That is my main concern.  The CARFAX looks way too clean for a 6 year old anything with 164,245 miles.  Even something known for reliability (like many Toyotas) typically has a lot more replaced, like a Nav screen, interior trim, shock/strut, or brake pads.  And surely the last set of tires (installed at ~58k miles) would be bald unless those were all highway miles.   I'm tempted to pay a local dealer to look up the VIN, but am not sure if that will be worthwhile.  Last time I did this, it was 100% useless, and I felt scammed - they noted the bumper was replaced years ago and that's it.  A 5-year old could spot the accident damage, even though nothing was on the CARFAX.   After giving the dealer a call, the truck may have a hard shift, but they have to verify with their mechanic if that's even a concern.  And I've test driven about a dozen of these now, many near Chicago, and half the trucks shift hard/odd at all throttle positions.  The ones with aftermarket lifts/larger tires shift terrible, and 3 stock trucks shifted so violently I thought the transmission valve body was going out.   At this point I'm conflicted, as I need a vehicle, and am coming up short locally.  Northern trucks in this price range tend to have either multiple owners, a lot of mods (lifts/oversized tires without re-gearing), and are generally in rougher shape.   If this truck showed up in your neighborhood for $27k and you had to purchase it sight-unseen, with the possibility of needing a 10L80 rebuild, torque converter, or rear end - would you do it?  I'm convinced most of the 10L80 trucks I test drove are broken, they can't all shift so bad, with massive flares/slipping/lurching and mis-matched downshifts like a teen driver learning stick.
