All,

78 280z, EFI.

There is a relay that is under the glove box, right next to the vent pull knob.

I dont know what is for, but it clicks when i turn the steering wheel. It only clicks when the steering wheel is at a certain position. If i go full lock either way it does not do it.

Does anyone know what that relay might be and why it would click when i turn the steering wheel?

Thanks,

 

Wire colors of the wires on the harness side?

Have you looked through the BE section of the FSM?

Only thing I can think of is the horn relay clicking because of a grounding fault in something related to the wiper pickup on the back of the steering wheel.

So...... Does your horn work normally, or has it been disconnected because it kept going off when the PO turned the steering wheel?

Thanks all, yes i finally found in the FSM and its the horn relay. I currently have no horn connected so i just hear the click. I should just pull the steering wheel and check the ground?

 

Woot. I like getting the weird stuff on the first try!

The horn is supposed to sound when the wire up through the steering wheel gets connected to ground (through the metal of the column itself). Problem is your wire is getting connected to ground when it's not supposed to be connected. It's only supposed to make connection when you press the horn pad. Is your steering wheel stock and your horn pad normal with all the stock parts (like the spring) installed? Have you ever had the steering wheel off and maybe mangled the slip ring connection?

It is not stock and i have never had it off. I just recently acquired the car and still go thru a plethora of issues. Ill take it off and see whats going on in there. Thanks.

Good luck with the fix. It's probably something relatively easy to take care of.
