SOURCE: 1999 toyota corolla Horn doesn't work.

Usually the wire from the steering wheel is Green w/Red and the wire to the horn from the fuse box is White. There is only one fuse, sometimes shared with the emergency lights. Check to see if there is power to the horn itself with a volt meter.

SOURCE: horn does not work

check B+ in the horn pin and check the ground on the horn if there is B+ and B- just change the horn if there is no B+ on the horn conector replace the relay .
B+ = battrey power
B- = battrey ground

2000 VW golf horn won't work, fuse is good , relay 53 is good but changed it anyway. No voltage reading at horns. Tested horn off car and it is fine


Did you check the power to the relay? and then the signal wire (ground) at the relay to see if it's being signaled? Otherwise you may have a clockspring or module problem not allowing the signal to pass through to the relay.

My horn won't work. I had it looked at and was told that the actual horn works it connected to a direct power source. The fuses seem to be fine........any ideas what it could be?


It could be a number of reasons such as a wiring problem or the switch is bad where you press on the steering wheel to make it sound but the most likely cause I would think would be the horn relay, The horn relay is located in the engine compartment fuse panel. I have given you a picture of the fuse and relay layout and the horn relay is the one in the number 40 position. I hope this helps and good luck.

The low beam head lights will not come on, changed new bulbs and fuse is good


Switch RELAY # 45 with #46, do you now have low beams? If so, replace the relay OR clean it by pushing it in and taking it out several time, which worked for me. BUT I keep a spare relay juuuust in case. Very common problem with Envoys and Trailblazers.

My 2003 Alero's horn doesn't work. Checked the fuse and it was fine, replaced the relay and nothing changed. Any ideas?


Check with a voltmeter that current actually reaches the horn connectors. If it does receive electricity, then the horn has blown..(no pun). If it doesn't receive electricity then the cable has been severed somewhere between the fuse and the horn.
