a couple problems
 

alright let me get this clear my buddy bought this truck because he needed it right away. the lady said that the key got broken off inside of the ignition and that's why it starts with no key and we looked inside of it and there is nothing in it so i researched that and found this site
Ignition turns and starts truck with no key why? - Ford Truck Enthusiasts Forums

his truck is a 1989 f250 regular cab with a standard bed he got it for $1200 so kind of not a bad price

The other problems

1. the tailgate doesn't come down
2. the passenger side door locks but the lock comes out of the door and you can unlock it that way.
3. the engine light comes on when it idles but not when moving
4. the left blinker doesn't work
5. when the regular lights are on one hi beam is on and when the hi beams are on there is one low beam.
6. AND the windshield wipers don't turn on

Can any body give me suggestions so we can fix these problems. thank you
