Power Wheelchair Diva

So I have a 2017 DJ.....it has less than 40,000miles. I don't drive much as you can see. I'm battling Cancer and there days... honestly weeks that my car will sit and not be cranked. I'm in Georgia so we get cold winters but nothing like up north or Canada. I use a power wheelchair and had a winch switch connected to my battery to pull my power chair on my wheel chair carrier. My car started going dead in late October of 2022. I will mention that my husband before he died.....in 2019 he used the UConnect and it wouldn't shut off. It stayed on until it drained the battery. The dealership then said no issues. Fast forward to 2023, my car went dead again. Tested the battery needed a new one. Went to the dealership because no one in my town wanted to install. Everything was fine after battery installed. Jump to 2024, driving home my panel lights flicked. Immediately I thought Alternator going bad. Had it checked...no battery and alternator were fine. Sent my car to the dealership because it kept going dead. They had my car for a week. No issues. Car sits for as I said days even weeks no movement. Thought okay it's going dead because I hadn't started it. End of 2024 sent my car to another mechanic. He had my car for a week. Once it was charged no problems. He said that my winch was the issue. February of 2025, for week car was dead...I left the radio on. Got jumped. Last week went go to my chemotherapy card dead. I bought myself a pretty decent jump start... Tuesday jumped my car myself...started it today...fine? Could someone tell me what they is wrong? Noticed today that my windshield pump isn't working...that fuse can cause a draw but I really feel it's my HFM and UCONNECT that is the issue. Thoughts and opinions are welcomed. I got Cancer.....life is hard enough. I need my car! 🙏🏾❤️
