Rx7 horn problem, connected directly 2 battery it works but when i push the horn i dosent and i cant locate the horn relay or fuse..

If I remember correctly, it should be on the passenger side of the firewall next to the fuel pump relay. Kind of oval shaped with 3 wires.

1 , fuse , 2 , ground , 3 , relay , 4 , button it self . Pull the wire off the horn and with the clip end hooked to a GOOD ground . probe the wire that you removed and have someone push the horn button and see if it has power .to light the test light . If it dosent ,, then take the clip and hook it to battery positive and probe the wire again . Sometimes they use ground from the button to activate it . . Hope that helps .

it could be the relay and it could be a faulty horn contact under the steering wheel

Check to see if there is 12 volts at the horn positive connection when someone pushes the horn button on the steering wheel. If there is voltage, and no sound, you need a new horn. If there is no voltage when the horn button is pressed, you need to troubleshoot the rest of the electrical circuit. First look in your fuse box for a blown horn fuse. Then try replacing the horn relay.

Find the wire at the bottom of the steering column that comes down from the horn button, or locate the wire at the horn relay.. Cut this wire and splice it to a wire that goes to one side of a push button switch. Connect the other side of the switch to the metal chassis of the car, which is ground. A metal part of the dashboard frame will usually work.Then when you press the button, it will activate the relay and sound the horn.

wire doesnt work

I would check for the following:
1. Fuse
2. Relay
3. Wiring
4. Horn itself (disconnect it from the car, use a wire to connect to horn and tap it directly to the battery, if it horns then it is ok, if not probably need a replacement.
5. Push button on the steering wheel
6. Rotor contact on the steering wheel

Could be the switches inside the steering wheel. But much easier to swap the relay first and remove it as a possibility. You can also jump 12 volts directly from the battery to the horn with a long heavy wire just to make sure the horn is good. Saturn relays are to the left of the passenger's knee
behind a velcro fastened panel.

get two seperate wires and connect it to terminals of the horn then connect it directly to the battery and see if it will work. if not, then your horn is busted.

with the horn you can run a wire from the battery to the horn to check it if that dosent work then it is probably the contact wire inside the steering column, I cant remember the name of the part but this should fix the horn and cruise problem.
