horn and spray nozzle problem, help.
the car is a 93 240sx. My horn and spray nozzle does not seem to be working. I've checked the fuses in the engine bay and the driver's side.I've checked the horn pad contact. I've looked at the horns and it seems to be connected to the wire. I don't know where to go from here. I don't know anything about wires or anything that has to do with electrical. If anybody can give me instructions on what i need to do next, I would greatly appreciate it. Now about the spray nozzle - i've used a pin to try to clean the holes in the spray nozzle. I've looked at the tubing that runs from the reservoir to the spray nozzle and it looks fine to me. What next? How do i remove the spray nozzle? Please forgive my retardedness. Again, any help is appreciated.
Welcome to NICO. Dont feel dumb every body starts somewhere.
Lets start with your washers as that will likely be the easiest. Try to pull one of the hoses of the nozzle from inside the hood, once off try operating your sprayers and see if water pours or sprays from the hose. This will help determine if the pump even works.
on your horn you will need a volt meter or a test light to check the circuit. do you have either of those things?
you can also test to see if the horn works by itself if you have any wire at all. you do this by hooking one end of the wire to the positive battery clamp, DO NOT let the other end of the wire touch any metal on the car. unplug your horn and where the horn connector was touch the other end of the wire to that spade terminal. only breifly touch it as it will honk your horn if your horn works. This will simply tell you if the horn can honk.

Thank you for your reply. I'll go ahead and buy a test light and then try your suggestion. I'll let you know how it goes.

Re: (NISTECH)
Sorry it took me awhile to respond. Been busy with a lot of other things lately. Anyway, i tried the wire test for the horn like you suggested and the horn honked. So, what next? with the test light? I also pulled the tube from the spray nozzle and tried to see if water would pour / spray while operating the sprayer, but nothing happened. So if it is the pump, where is it? Is it near the reservoir?
First go through the fuses with the test light. Do this by finding a good graound for the aligator clip, turn the car to the on position, engine running is not nessesary unless you wanna run the A/C to stay cool. take the probe end of the test light and touch the back side of each fuse on both sides, on the backs of the fuses there are small slots you can check for power with out pulling the fuse. It will take you less then a min to test every fuse in both fuse boxs. If you have power on both sides of the fuse it is good, if you have power on one side and dont on the other it is bad. Now be aware if you have no power on either side of the fuse it is not a powered fuse at that point and you dont need to be concerned with it as both circuits you are working on are live when the key is on. The reason I want you to do this first is it may simply be a blown fuse since you clearly have 2 dead electrical components.
If that all comes out ok the pump is mounted on the washer bottle, it should have power at all times and the wiper switch supplies the ground.
The horn if the fuse is ok will need to be tested at the relay. The relay should be gray or black and is 3 terminals inside 2 are parrellel and one is 90 degrees to those 2. The one is power if you put the gator clip on the neg batt cable and the probe of the test light on that terminal your test light should light up. If it does you wanna jump it to the terminal that has a solid green wire under it, NOT the green with white tracer wire, again if all is good the horn should honk. If it does now you need to jump your test light from the power terminal and put your gator on the terminal with the green with white tracer wire and push the horn button. the test light should light up. Those are all the things that should happen , if at some point one of those does not happen that is your problem, when you find it post back your results. If all horn tests come out ok then the relay is no good.
