91 Toy Camry Horn will not honk. Is this a

You may have wires that have become crossed. The wire to the horn and a hot wire have probably lost the outer insulation and crossed each other causing the horn to start honking when it is connected. Check the wires with an electrical tester.

the horn is simple , a horn a relay and switch, and fuse 15?.

but is complex by other factors.

1: the clock spring . no air bags in 1991, so very easy.



there are 2 ways to diagnose any horn..

1: hot wire it, does it now honk? if yes, hot wire the relay does it honk now?

2: or use any voltmeter ever made and find out why.



#2 is the save way.



id hot wire the horn and make sure that 1991 ground bolt

mount is really still at ground potential. id bet that bolt has

long sense rusted, and is useless, like most are by now.



the fuse and relay are both in the PDC

the PDC means, engine bay fuse box in gringo. (non jargon)

here is 93 for free.

see horn page one and the 2 tests.

or see the schematic.

at there, see the fuse box see fuse 15 (PDC 15?)

same chapter, see PDF page 90 (sheet33)



as you can see if the fuse is good.

12vdc arrives at the Horn relay on 2 pins.

if the horn switch works the relay ENERGIZES (closes)

and 12vdc arrives at the horn, and it honks

if while honking, the horn casing is 12vdc,

then means the horn is no longer grounded, a common happenstance.



if the relay dont energize check the horn ring contacts or connectors to it for continuity.

the relay can be tested, in the car.

like this.

honking

pin 2 and 5 are 12v

pin 1 = 0 volts

pin 4 is 12v, if 0v the relay is bad.



easy huh., ?

check horn relay in engine bay fuse box

its possible that the relay is the problem as most relays have a second power feed wire,if it shorts to the horn side of the relay it can blow the horn.doesn`t happen very often but it does happen.this could explain the horn blowing without the fuse in.you can get a door key made at a lock smith to solve that problem.

If blowing fuse when honking horn you have a bad ground to the horn or the horn itself has a internail switch. Try using a higher amp fuse, good luck

sounds like a electrical problem. When you turn it is completing the circuit some how, sounds like wires are touching each other and making the horn honk when turning. easiest thing is remove the fuse if possible.

Check to see if you are getting power to the horn.If you are then you need to replace the horn itself.If your not getting power there then check the fuses.if there ok change the switch.

Sounds like the horn relay was stuck or the the switch in the horn pad. A fuse couldn't cause it to stay on. Does the horn still work?

horn is bad .

I HAD SAME PROBLEM SOLVER OF MY MOMS 1996 CAMRY ABOUT HORN GOING OFF AND CAR WOULDN'T CRANK. JUMPED IT OFF AFTER A FEWW FRANTIC MOMENTS OF HORN HONKING-- FOUND OU IT WAS AN ALARM THING AND YOU CAN SHUT IT OFF BY TURNING IGNITION KEY TO ON POSITION AND MOVING TOGGLE SWITCH AT DRIVER KICK PANEL TO OVERIDE THE HONKING HORN PROBLEM--STILL NOT SURE WHAT CAUSED IT TO DO THIS AT BEGINNING. BATTERY WAS FULLY CHARGED AND HEADLIGHTS REAL BRIGHT TOO. COULD HAVE BEEN A DOORLOCK MANUAL MALFUNCTION--BEEN OK FOR A WEEK NOW.
