My 2003 Toyota Corolla LE has lost all power and gears lock up, My battery light turns on and off but when I popped the hood and pressed down on some sort of electrical connector(I don't think it's a fuse) my hazard lights start blinking and I have to press the unlock button on my key to turn them off. I then am able to shift gears and all power returns. I had my alternator checked at a autoparts store and there was a shortage I then had the alternator replaced and the issues persists. I had my battery checked and was told that there's nothing wrong with it. Any help will be very much appreciated! Please, thank you!
