Hello. I am a new member here so I hope this is where I can hopefully get some help. I have a 1998 ES300. Every time I use my rear defog, my lights go dim and in a day or 2, I have to jump start my car. I have also noticed that if I have my windshield wipers on and rear defog, my battery gets drained real quick if I’m sitting still. If I never use my rear defog, I never have issues with the battery. Someone please help, I can’t figure this out.
