I am looking for a good diagram of wiring in the steering column for volvo 940 (1993).

The horn in my car does not work, because of faulty ground connection at the buttons on the steering column. However, in view of the air bag I want to be certain about what I am doing before getting there... Haynes manual wasn't much useful in this respect.

 

You may be able to find a diagram on this site:

Volvo 940 service & repair manual


This section at least gives a description of and procedures for working around/ removal of airbag.

Volvo 960 airbag service manual

 

the volvo 'greenbook' wiring diagram manuals don't show the 'steering column' per se, they show each sub system thats ON the steering column as a seperate diagram (eg, turn signals and eblinkers, cruise control, wipers, horn, airbag are all seperate diagrams
