I really could use your guys' help please I've tried everything absolutely possible underneath the sun I am dealing with a multi battery system and there is an axillary battery that I think might be the parasitic drain I have swapped out the battery itself and put a brand new battery in there I also swapped out the battery current sensor and now my car won't start I have a 2019 Chevy Cruze I'm trying to look on all of the forms that I can find and I am not coming up with any answers as to what the f is going on with my car when I talk to the mechanic at the Chevrolet dealership he said oh it sounds like it could be a maxi fuse I've already swapped out all the fuses I put brand new fuses in again I have not been able to access the relays cuz I have to order them offline and then I was looking into also a fuse box for under the engine engine fuse block and then I'm going okay I don't know what to do because I've tried absolutely everything I swapped out the battery the one night and then it for the car ran and all that stuff and then the next day I had to get BCAA to come jump me and my car wouldn't even stay on longer than 5 minutes and the car shut off and I was over a month ago and now there's snow in the ground so I can't access the car that I beforehand with the openness obviously of it because it's covered in snow I really need a solution here because I don't know what to do I have a 2019 and I've maintained my car up until this point and now it's just too much headache I don't know what to do I don't know if it's my starter I don't know if it's the alternator I can't access those pieces because they're underneath the car against the firewall and like I said there's a lot of snow in my car I bought a brand new battery charger and I charge the battery and that was fine and then I charge the AC Delco battery that was in the car that is in the house I have not put that back in the car cuz again there's snow all over my car so I can't get into the car itself with batteries and hand obviously I don't want to fry the battery or whatever I need some answers here please somebody if you can please give me an idea on what to do with the auxiliary battery obviously I might have to take the battery out and examine the battery tray for corrosion and then with that being said does that mean that I need to buy new battery cables like does that need does that mean I need to purchase everything brand new once that happens I'm not really too sure about that whole process of someone can please give me a little bit of insight on that that would be also greatly appreciated please let me know

 

PLEASE….

Start a new thread for this question and I will advise you in that one - or if you already tried posting and it didn’t get an answer, please provide a link.

It Would also be helpful if you provide more than just 2019 Chevrolet for the vehicle, such as model, chassis (15/25/3500), engine size, and w/ or w/o 4WD, as that information will be needed to find the appropriate information to help you understand what steps to take.

 

.....

I have a car ...but I know this is for trucks but I know I definitely have a auxiliary battery and main battery ...so I can't find any wiring diagram or schematics...I've had to find info by going through the gm side...and no diagrams I find show me any aux battery...so it's a little difficult to find the info I need....it took me three years to find the proper radio wiring harness ... because apparently my dash was swapped out before I got it...I got the car gently used at 26,000kms...car was absolutely mint....I definitely gave the Chevy Cruze the best racing reputation...in all of the gvrd...but once I got t-boned I kind of gave up on my car .. because of all the damage my ride or die Chevy Cruze took a huge hit for me ... I know that a lot of people keep on telling me to just get rid of my car but at the end of the day Chevy Cruz took a bad hit for me I absolutely respect that cuz nobody would do that.....my car is loyalty... After the accident I thought my car was done ...but I turn the ignition and chevy Cruze started up ..and I had no dash issues at the time.....I got t-boned not this summer the summer before 2023...it's taken me this long to find doors ... To now find out a year later that my car has the same doors potentially as the 2016 Chevy Cruze to the 2019 not just 2019 only do you know how hard it is to try to find 2019 doors it's absolutely like a needle and freaking haystack is ridiculous so now that I found that I'm able to widen the Horizon when it comes to looking for potentially doors for the car for the driver side is where I got t-boned the driving door I couldn't get it open for the longest time and the back door I tried to open it all cuz it doesn't sit properly way it sits I think the rock is a little bit bent on the bottom too and the car the car still was like a freaking champion it was ridiculous after the accident happened and I turn the engine and I did not think the car is going to turn over but it totally didn't music came through and everything that's wrong and no problems just the card look like it got punched out on the side right and then spring break of 2024 is when something happened in the dash lights just went out so I've been trying to figure it out ever since slowly here and there whenever I can have the time to pick up the car when I'm in the area where I can actually look at the car without being snowing or raining or whatever.... I got a chance to pick up a diagnostic tester...so I plugged it in...and it said replace battery current sensor...so I went to Chevrolet in 100 mile house bc ..and ordered the part ...so I swapped the part... And really high hopes thinking that this was going to be the solution to my problem with the no dash lights so that's what I had read online and many many reports of different websites and everything like this through the Chevrolet website through the GMC side of it as well because there's no documentation of the Chevrolet Cruze having any additional batteries but I keep finding schematics online and it's never my car and it's never the same thing but I know there's definitely more than one or more than three batteries at least in the car and I don't know why or what but it's really hard trying to find any wiring diagram for the axillary battery to try and reset it somehow and make force it to calibrate so that's a bit of an issue......I know I have at least two batteries because in my trunk ....I'll post pics and see if you guys can give me an answer ....

This is my trunk ... Apparently the small one with that cover on top of it in the second picture apparently that's the auxiliary battery but I can't find anything that says that it is or that it isn't cuz that's what I need to try and reset somehow that's when it's connected to the battery current sensor

And then this right here apparently is the auxiliary battery which I didn't know I thought that was an amplifier this whole time cuz it's the 600 amps on it like there's writing on these little post terminals and they say different amperage on them and I try to find like a QR code or anything like that so I could take a picture of that but I can't seem to find one anywhere on that battery whatever it may be and then there's another thing beside it in the compartment there too so ....
[img alt="If you can really look at this picture here you can see it there's three different objects in this trunk right here there's a silver thing that's there and there's that black one there and then there's that big battery that's battery I just put into the car that I bought brand new and for some reason that battery is not keeping a charge.... I tried to see if that was a battery the one that's beside it there with all the terminal posts on it and when I put the try to test the terminals....

It doesn’t matter to me that this a Cruze, but I still need more info to help you figure this out. I can’t provide any accurate info without knowing what to look up.

2019 Chevy Cruze - what engine? Is it equipped with stop/start or a hybrid?

Also, please start a new thread on the Cruze board (Chevrolet Forum - Cruze) so we’re not working through a thread that’s not related to your concern.
