Hello all! I am new to this site so please bare with me but I decided to create an account to reach out to my 86 family for some help. A couple of days ago, I was driving on the road and my car abruptly turned off and made some beeping noises and threw some lights on and the power steering went out. I managed to drive to the am empty parking lot and then I couldn’t shift out of gear to put it into park so I came to an complete stop and held on the brake and took the me out. I used the shift bypass button and got into park and tried to start my car. It didn’t start and didn’t make any noises like it was even trying to start. Here is what is also wrong: the windows won’t roll up or down, the radio doesn’t work, and the windshield wipers don’t work yet the lights and everything else still do. I went to get my battery tested and it was all good and didn’t need to charge or anything. My main guesses after doing some research are that the alternator, starter, or spark plugs have gone bad. Please help me find out what is wrong with my car! There are no mods to this car other than muffler delete. Has 68k miles and has stock everything! If you need any additional info I’d be more than happy to provide you with it! Thanks!
