I purchased a 1991 Bronco and immediately found out it had a terrible battery drain. There were several items I knew needed replacing I was hoping one would fix my issue. I was checking the drain with my amp meter. First the original wiper motor barely worked. So I replaced it and then noticed the worn out wiper switch wouldn’t turn it off. I replaced it. The solenoid was original too so I decided after 30 years it could use a new one. The solenoid fixed the battery drain. Went from 8.6 to .41. Then I also notice the ignition switch would hang up sometime. I replaced it and wow what a difference. So for about $100 in parts the Bronco is really doing great. I’m not a mechanic, more of a parts changer but I feel pretty good about it.

It’s really a solid Bronco. No rust. The previous owner put the wheels and tires on. My mission has been to fix the little things. I installed kick panels (they were missing) and new thresholds. New wiper motor, arms and blades. New solenoid and ignition switch. Windshield washer pump. (YouTube has helped me understand the installation especially with the wiper motor and ignition switch) Just fun to drive around.
