The horn should have two wires going to it. One wire is supposed to be hot (battery voltage 12v). The second wire is open but gets grounded when the horn button is depressed, thus completing the electrical circuit and making the horn toot.
So, the first check is: are you getting 12v on one of the two wires?
the second check is: when a helper presses the horn button do you get ground to the second of the two wires?
The third check is: if you ground the second wire at the horn does it toot?
If the first check does not produce 12v, then the fuse is blown or the wire from the fuse to the horn is defective.
If the second check does not ground the wire, then the wire to horn button is defective or the horn button itself is defective.
If the third check does not toot the horn, replace the horn itself.
The fuses in a Toyota Corolla 2000 are for various components of the car. For instance, the fuses power the windshield wipers, the radio, the power windows, and the power seats.
No fuses are fuses no difference.Take one of yours out and check for size of fuse with unnamed ones from your local auto shop..
check the fuses for the head lights check the fuses for the head lights
Check the owners manual. I believe both fuse boxes have spare fuses. Yes there are spares. My 2006 Corolla, same generation car has them
The fuses in a 1991 Toyota Corolla are situated at two different spots, depending on the kind of fuse. Some are inside the car under the dash. There are other for engine components and these are located in a black box next to the wiper tubes.
It should be under the hood in one of the boxes w/ all the fuses....
The best way to troubleshoot why the taillights are not working on a 1999 Toyota Corolla is to first check all of the bulbs to see if one is burned out. Then check the fuses to see if there is a blown fuse. If the problem is still not found, a code reader in the ECU (computer) might show a code that will help find the problem.
the flasher fuse is in the fuse block look in your owners manual under fuses
check the fuses and then check the flasher relays
I would check that the switch works. It could be worn out or broken. If it does work, then follow the wires and see if there is a problem with them.
Scrap the car and buy a new one.
