All of my signal light are not woorking can you tell me or give a solution to the problem

Have you tried checking to see if you have current at the starter? If not, check the starter relay and or fusable link.

Going to have to tell us what you have done or tested
so far & how

Have no idea if you ever worked on any vehicles

NEED A NEW HEADLIGHT SWITCH CONTACTS ARE BURNED OUT

I looked over all the wiring diagrams can't find anything. I would check all your fuses under hood black box by battery

first test for power at the horn using a test light if no power then its not the horn check the fuse if fuse is good your problem can only be the clock spring which is located underneath the steering wheel,remove the wheel and its right there replace it and you will have horn power again.

look for a blown fuse in your engine compartment fuse box. if you dont find one there then check the fuse panel in the dash under you column. it could be one of the larger feed fuses in the engine compartment fuse box so dont overlook those.

try changing the sensor ,have a funny feeling that its reading incorrectly ,comes with age ??the internal components breaking down giving the wrong resistance

Wiper nut needs tightened. At the end of the wiper are there is a nut covered by a black cap. Just remove the black cap and tighten.

Check to see if there is power at the starter with a test light. There probably isn't. So your problem is the fusible linkin your positive battery cable.

try turning on the driving lights button if you have one..
