1998 Toyota Sienna Q&A

1998 Toyota Sienna Question: Horn malfunction

Because the horn and airbag are identified as 1 unit to repair the horn I'm told I have to replace the airbag, too. Anyone have a better fix? -
Answer 1
It is not uncommon for the horn contact to be part of the drivers air bag assembly. My only suggestion would be to make SURE the horn contact is your problem before changing the air bag. -
Answer 2
I hate modifying things from the stock set up but if in fact it is only the horn that is inoperative and the SRS/air bag system is OK I would put a momentary push switch on the dash. I can look at a wiring diagram and tell you what wires need to be brought to a push switch. -
Answer 3
HI, Had this problem last year...supposedly there was no longer a problem when I left the dealership...and then I was nearly hit by a large truck when my horn didn't work several days later. Went back again, and a creative mechanic tried cleaning out the steering column and the inside of where this all fits. Apparently there were very fine metal filings (just wear from over the years). We've never had another problem. Hope this solves your problem too. -

My 2004 Sienna has a dual-tone horn. The high pitch horn has suddenly stopped working; only the low-pitch horn still works. How to diagnose this problem? What must I check? Thank you.
