A few months ago the radio started staying on even while the key was pulled completely out, then the horn fuse had to be pulled because while sitting in our garage and the car not running, and hadn't been running for 12 hours, the horn started blaring, until my husband could disconnect the battery, then while driving home one evening in the rain, I had the wipers and headlights on the wipers would not shut off, even when put in the off position. They would not shut off until I shut the headlights off. I am scared for my safety as well as others to drive my car, and especially to use the cruise. I fear that if I do use the cruise it will stay on, and I will be involved in a deadly crash. No one seems to know what is the problem. It seems to really act up when the weather is damp or wet. The wipers will come on by themselves in the off position, with or without the headlights. Please help.
