Sienna '99 won't start after fixing horn on steering wheel

I was trying to fix horn on my '99 Sienna, now it can't start. Need emergency answer/advice. Thanks.

what I did: 1) disconnect battery, 2) remove audio control on the steering wheel, 3) loosen two torx screws, pull up air bag module, 4) detach airbag wire connector. After these steps, I pushed and tested the horn push-points, also tried re-connect battery to test horn, but it won't work (engine won't start this time). I then put everything back on in the reverse order. Now it won't start. I have lights on, fan is blowing, but starter won't turn. Radio/CD is not operating, though it has power and has display on. I try to jump start, but the starter still not turn. Over this time, I can see the battery is drained out, and everything now is dim. Door-open indicator on the instrument panel is dim-lit and blinking.

Any suggestions? is there switch or fuse I need to check?

    very much appreciate your answer. It actually was a bad connection on the battery terminal (due to age). I connected battery as tight as I thought acceptable, but apparently not. The tow truck technician came and wiggled the battery terminal, and know it isn't good. So he stick a small metal screw inside the terminal loop, so to make the connection tight. And that fix all.

Check your fuse box (driver side lower dashboard panel). Bad fuse will have middle wire broken.

I had to pull relay out for horn because my horn started blowing when I turned the wheel. How do I fix the problem with the horn blowing when I turn


To fix it properly, you would need to remove the steering wheel to access the wiring for the horn. It has most likely become chafed by improper routing and is shorting out when you turn the wheel. Another, perhaps simpler fix would be to find the horn wire coming out of the bottom of the steering column. Cut it, splice a new wire to it and route it to one side of a horn button you can install on the dashboard. Run a wire from the other side of the button to chassis ground. Test the horn for operation by pressing the button. No more accidental beeping.

Horn button and cruise control do not work on my 1998 Toyota Sienna. Air bag light is on. How do I fix this?


This is caused by a part called the clock-spring rotating contact ribbon, it is a coiled up circuit ribbon that connects the steering wheel button and airbag to the steering column electrics. it is under the steering wheel. It needs to be replaced. This can be a dangerous job due the Airbag, so if you do want to try and replace it disconnect the battery negative cable for 15 minutes prior to start of work. The part is about $150.00 You will need special tools.

The horn not workingI


The metal plate in reference above has small copper contacts. If they do not meet the horn will not work. We used a dremel on ALL of the contact point and it made no difference, the horn still only works about 5% of the time. After a whole lot of testing (I have the same issue with my 2000 Toyota Sienna) we found that the ground is weak, too weak for the relay most times. At this point I am going to run an alternate ground by "borrowing" the wire for the mute button for audio controls through the clock spring. The existing ground connects to the steering column. Before we discovered this I spent $285 on a new clock spring :(

My 99 oldsmobile alero started honking on its own from time to time. sometimes when i turned the wheel and sometimes not. then one day it started honking nonstop for 20 min. i pulled the relay fuse from...


ok its one of 2 things

1- behind the steering wheel between the column,there is a part called the sir coil,it allows the steering to turn with out getting the wires inside tangled,,this SIR COIL could be bad and making contact when it should not and causing the horn to sound,,,,you would have to remove the steering wheel to remove this part and its easy to mess this up,i would rec a repair shop to fix this,

2-inside the steering wheel is the air bad,which also contains the horn buttons inside,sometimes the air bag swells up and gets hard and applies pressure on the horn buttons inside and cause it to soulnd the horn,,if thats the case you will need a new air bag,,,i would also rc a repair shop for this as messing with the air bag system you can set the air bags off just with static electricity,,,,
but one of those should be your issue i think,,,there is really not way to test those parts unless your a dealer,so i cant tell you horn to test it,you need the special load tools and stuff,,,
Take care

Need connector block connections for horn wire,relay to button.


The horn switch provides a ground. If you have no voltage at the horn wire, inside the steering whel, I would suspect a bad spiral cable, or clockspring under the steering wheel.

Horn button on 98 Sienna


I just took a look into my steering wheel horn set up.
It is defective design. Only one of the two contact plates are connected. The ground from the spiral cable is not used for the horn. I can fix the first part, but the latter part will need a consult with Toyota service dept or HQ. If you have the same problem, let Toyota and nhtsa.dot.gov know about the problem. I've read a lot of fixes that didn't work. The normal suspects on the horn are: relay, horn (use the alarm to check or by pass the relay), spiral cable, contact plate, but my new one is that one of the contact plate is not connected and ground from spiral cable is not used for the horn. Just indirect contact from the steering shaft. You need to know haw to remove the air bag to look at that area.
