Weird Electrical Issues. Any help will be great!
I have an 05 Ranger, 4.0 V6. Never had any problems until last night. I went to go to the store and when I turned on my lights, my horn sounded off and would not stop until I turned off the light switch. Then I noticed the park lights and instrument lights would not turn off until I disconnected the battery.
This morning I went out and found that when I attempt to blow the horn, (I did remove the fuse to the horn last night) the wipers turn on. On top of that, now when I turn on the headlights/park lights, the wipers and the wiper-washer motor turns on and the park lights stay on.
There are no electrical modifications or add-ons. The radio is stock, no lights added and no trailer was plugged in to the tow kit (factory installed).
I figure the only thing it could be is what all the components would have in-common; the ECU???
Any advice would be great before I start throwing good money after bad on the wrong things.
Thanks in advance
