Hey our cruise quit working in our 2004 subaru Outback Legacy with an automatic tranny. How does a person troubleshoot this? The horn doesn't work either. Airbag light is off. The cruise would quite working from time to time, but now is completely dead.

Does anyone have a wiring schematic for this or a cruise troubleshooting guide?

I have an extra steering column for this car, so I'm going to ohm out both sets of switches and go from there.

Thanks
Jeremy

Every car I have had that has multiple problems like this has always been a vacuum leak. Hopefully yours is real cheap to fix.

The most common problem when those two circuits go out is a component in the steeing column (airbag system) called a 'clockspring'. This carries the current through the steering wheel so the circuits continue to work even when you are turning your wheel. For mor info, check out this site:

Good luck

I fixed it, it ended up being the clockspring. Not too bad a job.

Thanks
