My gear shift on a 2003 ford f150 pu wouldn't come out of park. Changed brake light switch and checked fuses. There is one fuse that if I take it out. I can then shift. My windshield wipers quit working too. When from working to not working over night.
On the brake master cylinder is a two prong switch that screws into it. If it cracks in middle where you can't see it. Fluid will leak into the prongs and blow the #15 fuse which takes out window wipers and inside light and gear shifter will not come out of park. Replace switch and fuse and all will work. Part cost $20.00. I have been told several different things for this switch. I was told it was a hydrolic switch, A brake fluid switch and a switch that runs the cruise control. I think it is the switch that runs the cruise control and that they had a recall on. Any way truck works perfect and thanks for everyones help.
