I suppose a faulty relay, or shorted wiring, could cause a problem too -- relay is under the RH side of the dash.

I'll be looking at the horns and relay this morning. I wouldn't suspect faulty wiring until after those are ruled out.
AC is still blowing nice and cold Andrew. Thanks for your help on that again.
