Hi everyone,

Once in a while the horn would quit when the wheel was turned 90 degrees,
and then begin working normally when driving straight.
Now it quit.

I couldn't find Volvo info or a good tutorial for the 940 with the steering wheel air bag.
There's no info in the Haynes service manual

The FAQ covers the 740 and mentions disconnecting the battery to safely disable SRS. Is a ten minute wait OK to start removing the steering wheel?
Is there a Volvo service bulletin for this?

Details like removing the plastic horn buttons are fuzzy, and now there's no
junk yard university and plentiful spare parts if something breaks.
I'd like to know more before I start the job.

Do the spring loaded horn contacts and slip ring just need dressing or wear out?
Are the slip ring and contacts asked to carry too much current?
Adding a horn relay is no big deal, how many people opt for that?

What specific parts should be replaced?

Thanks, Bill
