Reset Climate Control?

Did some searching, but not finding anything on this. Maybe I'm not using the right search terms.

Anyway, 2015 Silverado, about 25k miles. AC started blowing hot. Drove home and parked it. Figured it was the issue w/the AC lines I've read about over and over.

A couple hours later, I go to start it, and it acts like it has a weak battery. Drive to the store and back home. Turn it off and try to restart it... no go. Throw a battery tender on it overnight. Try it this morning and nothing.

Start thinking the dead battery may have something to do w/the AC not working. So I removed the negative cable and threw a 'fast charger' on the battery. Let that sit for about 30 mins. Reconnected the negative cable and she reluctantly started up.

Now my question is this... Would leaving the negative cable off for that 30 mins reset my climate controls? Or is there a procedure I need to follow? Could the dead battery be the reason why my AC is blowing hot?? I just find it weird that both would happen at the same time.

It's still under warranty, but with tomorrow being a holiday I thought maybe I'd look into it a bit since I can't get it to the dealership anyhow.

Thanks for any help you can give.

First, my advice is take it in to the dealer.

 

But if you need to work in it yourself, you'll need a set of AC gauges to know what's going on with the AC. Again, my advice is take it to the dealer.

And yes disconnecting battery will cause a reset of climate control. One method after reconnecting, key on, engine off. No touching of controls. Just let what happens happen for the next minute or so. The remove the key close driver door. (Generally signals a completed cycle to the truck/bcm.) The get in. Key on, engine start. See what happens over the next bit while driving

If the truck is under warranty, take it to the dealer to get the freebies. You screw with it, warranty will turn into CP, customer pay.

I don't like to see anybody getting screwed on their vehicles, especially when car dealers doing the repairs.

 

Always keep your receipts so you know what they did in the past. With my 2 vehicles, I have two 6 inch thick notebooks of everything that was every done or installed by myself. It's a "history folder".

 

Outside of warranty, ask the people of the forums what to do.

Don't confuse the service adviser and tech by trying to guess the problem.

 

Give them the symptoms to pass on to the tech and let them do their own diagnosis.

 

 

Nothing a tech hates more than someone they don't know/don't have experience with trying to tell them how to do their job.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.
