Z31 horn not working after replacing headlight switch

Post by **coolvegasZ31** » Tue Jun 20, 2017 4:49 am

I have a 1985 300zx 2+2 NA 5 speed. I recently replaced my headlight switch and now my horn and cruise control doesn't work. I have searched high and low and it seems I am the only person in history to have this problem. Please help

The fact that the issue started after replacing the combo switch would suggest something god disconnected or popped a fuse in the process.The horn should be the easiest to troubleshoot.

Apparently changing the fuel level sending unit and the spark plugs is easier for me than the horn. Additionally, I cannot get the steering wheel straight anymore since putting in the new headlight switch. I have searched high and low and without success. I am beginning to hate the car and I am tempted to sell it

did you get it sorted?

No. I gave up trying and it is too hot in Las Vegas in the summer to fool around with it. I might revisit it in the fall when it is cooler and that is when I drive the Z. I am used to bmw forums that are more active and the responses are full diagrams and pictures

Sorry, a horn problem isn't very common and the horn wiring diagram is pretty much a straight line,

getting the steering wheel centered after removing is a bit difficult. what i do is drive in a straight line and let it center itself and then pop the wheel off and align it up. then repeat. took about 3 times to get it just right.
