I second Joe's suggestion. I've had relays go bad for both reasons
mentioned though not on the Pantera. I have also had one with corrosive
leads that caused excessive heat and melted the relay and relay base enough
to be noticable and resulted in cycling the compressor until I noticed.
(also, not on the Pantera)

I haven't thought any at all about this circuit (and possible
upgrades) but
first look and I am thinking remove the condenser fan from the AC de
icing
switch.A Letting it run all the time the AC is on is first
thought.A Using a
pressure switch on dryer would be investigated (but that is getting
more
complicated) KISS

Nick,
More info please.
Is it a stock relay or a modern replacement?
Stock location, inside the cabin?
Stock fan?
I don't have any answers but more info might help the electrically
smart
people come up with the answer?
