Ok I just bought a 88 crx dx. It doesn't have a radiator,battery,and had half the interior out. When I hooked up a battery I got in and went to turn the key. All of a sudden the horn started to honk. And everytime I hook up the battery the horn goes off. I even took off the horn button(if that is that what its called) but it still does it. What can be my problem? Please help.....

 

probally the horn wire is bad, touching something it shouldnt be.

for the time being you can just remove the under dash fuse.

 

Thanx any one else have any suggestions?

 

Unplug the wiring to the horn.

 

Is the horn pulsing or steady? Are you sure someone didn't put an alarm in the car? some alarms use the factory horn instead of a siren.
