Unhooking wires from zone valve wouldn't shut the fan off, there is something shorted out and sending power to the zone valve and fan

Remove the green wire from the thermostat and see what happens

Try at the furnace end. If it is a short it could be after the thermostat.

No strips aren't on.  Where is the G wire in the furnace? I had the front panel off and didn't see anything obvious.  The tstat wires seem to be connected to a lot of wires with wire nuts.

I'm at a loss.  Hopefully I can get someone out tomorrow to look at it.  All the weird unexplainable crap happens to me. 
Thanks for everyone's help.

OK so I talk to my owb dealer and he suggested tapping on all the relays.  The big one is the fan delay relay and 2 smallerr ones the installer put in.  Fan started cycling normally.  I've located a new fan relay for $15 so will install that and see if it stays working.  Dealer said once they get hung up like that, they will usually go bad.  It must have been a coincidence that it happened when I opened that zone valve.  crap like that always happens to me so why can't I win the lottery?? :)
Thanks for everyones suggestions.
