Is it necessary to reprogram the clock spring after replacing it. Is there a workaround?

 

what’s there to program isn’t just wires that move

 

my mechanic replaced mine because the horn wouldn’t blow and he replaced it with one I got off eBay and said when he installed it the warning lights all lit up so he put the old one back on. He said he researched it and that it requires reprogramming. After I got my car back I noticed the horn blows sometimes but not always.

 

Yesh that’s what I thought as well. The Toyota dealer I took it to a few days earlier wanted $3600 to replace it snd the sir bag snd the sir bag was never deployed. Amazing what they want to charge for a simple repair.

 

If all other buttons work on your steering wheel, and it's just the horn that's intermittent, chances are good the clock spring isn't the issue. I had a horn that did not work at all, but after disconnecting then reconnecting plugs under the horn cover and to/from the clock spring, as well as moving wires and checking all connections, the horn worked as normal and continues to do so for more than a year now. The last page or two of this thread may provide some practical solutions. Horn not working - Page 4 - ClubLexus - Lexus Forum Discussion

 

This is some good information and I will check into removing and reconnecting it.
