q**i 发帖数: 174 | 1 do you have a multi-meter? if you can detect voltage (with
the horn button depressed) on the terminals, the horn
itself went bad.
most cars have two horns: high pitch one and a low pitch one. they
are reasonably priced: about $20 a pair for aftermarket ones
at pretty much any auto shop (I would recommend a brand marketed
by an Italian company - something like FIIA - but made in
east Europe).
People normally want to have a loud horn (high db output), but
most manufacturers only gives you db outpu | c***k 发帖数: 4 | 2
有关电路的问题,查起来一般都很费事,所以labor往往很贵,$50+/hour。
建议你自己动手:
首先,看看是否有相应的保险丝烧了。
其次,检查开关,控制继电器,喇叭这三个东西是否都好。这三样都应该
不贵,让GARAGE修也一样得掏钱。当然,你也可以试试看能否自己修好,
可以省下part的钱:),GARAGE绝对不会花这labor。如果你找不到它们,可
以到Pepboys找本手册来看看,也许没有用继电器,也许还有其它part。
喇叭可以直接用车上的12伏电源试其响不响,其它也很容易测。
如果这些parts都是好的,则可能是线断了,要找到断点一般很困难,因为
一般都没有布线图(而且即使有也不见得有用)。可以考虑干脆自己另外布线,
也就是说另连一根线代替,GARAGE也常这样作,这也就是为什么说即使有布线
图也不见得有用了。另外,导线断了的可能性一般很小,通常都是一些接头
处接触不良。

The switch is normally under the center of the steering wheel. You may have
to remove the cover to see it. That's why you might have to see the manual to
learn how to remove the cover (can be simply pull it out).
The horn and the relay normally are located in the engine room, you still
need
to check the repair manual for their locations.
Different cars of different make, year, engine type and size, etc. have
different locations, this is why I cannot tell you where they're located. Go
