It takes a lot less power to blow a horn.
I have been reluctant to use horn or lights as an indication of a good battery.
To find out definitively, jump start the vehicle; if it starts you need atleast a batter maybe an alternator as well.
If it does not start with a jump possibly bad starter or power to the starter.
I would eliminate the battery first.

04 Impala 3.8 horn blows low volume and sounds weird


sounds like the diaphragm in the horn is worn/dried out. check to see if you have battery voltage to the horn with either a test light or voltmeter and the horn has a good ground as if not then the horn won`t operate correctly. if these are good replace horn.

Horn won't blow in my 2001 toyota corolla


CHECK for bad grounding of horn itself, rust and oxidation may not allow it to ground, also try "jumping" a wire from battery to horn, if it blows horn itself is good, contacts inside steering wheel button may be bent flat, or wire bad..

Horn stays on


Normally there is a horn relay, try replacing that. The contacts can weld together and keep the horn on. If you take the relay out and leave it out, you won't have a horn but at least it won't be blowing all the time.

2003 - RX300 I'm tring to change the battery,when I connect the negative terminal, the horn blows and won't stop... I've turn the key to start and nothing happens, the horn keeps blowing.......


I would check to see if this is a relay problem for the horn. Remove the relay for the horn and see if you can swap it with another to confirm it is bad. If with another relay it doesn't stay on you no it was just a relay so go get a new one. The only other thing could be a security issue and when you discharged the power by unhooking battery the vehicle is acting like it has been broken into. But i would say it's a relay problem. Good Luck.
