I don’t know what to do now it is hot and I have no AC. I can’t control radio or AC and the screen in the dash is black or blank I guess. I don’t know how to check and make sure the screen is working or needs to be replaced. I changed all the fuses. They were all blown for the audio and stuff. I can’t pinpoint where the problem is now. I don’t have the money to take it in and get charged out the Ying Yang and it be something simple that I can do. I’ve taken it all apart and put it all back in plugged in properly. Anybody have any advice or had the same problems? There’s not much in the forums about this and if there is they don’t really elaborate if they found the problem. Thank you

 

Same has recently happened to my 2016 Maxima Platinum after installing new battery, except my A/C still works fine just a black display screen and no radio/audio/cameras/safety features+tpms sensor, as well as key fobs no key id detected and remote keyfob features all not working(have to touch start car/unlock with valet key when unlocking etc). Car is still under extended warranty CPO (Gold Preferred i think?) with 70k mi. lasts until 100k/February 2023. Are your remote keyfobs still working/recognized?Am planning to take in to dealer ASAP (despite wanting to fix it myself) but wanted to learn more about my warranty/rights so I don’t pay for a bunch of stuff that should be covered etc. Anybody have any input/suggestions would greatly appreciate any light shed on these annoying issues, cheers!
