I have had a direction issue with this truck for a long time. I have changed the seat switch, brake switch, park brake switch, and both joy sticks. When you sit on it there is no direction sometimes but the raise, lower, tilt and side shift work fine. Have to get off it, turn key off, put in neutral and put park brake on. I then turn the key on sit on seat release park brake, press hard on the brake pedal then put in forward direction and it will work 50% of the time. Any input would be great! I also changed a square box relay in the back that you can hear click when you sit on the seat.
