91 Integra Condenser Fan Keeps Running

All,

I'm having a problem with the condenser fan in my 91 Acura Integra LS.
After I turn the car off, the fan sometimes turns on and keeps running
for hours. This happens even in very cold temps and after running the
car for a few seconds. I'm sure it's the condenser fan and not the
radiator fan. I know the timer circuit is suppose to turn off the
condenser fan after a max of 30min, but something has obviously failed.
I know I could fix the problem since it has to be a faulty timer
circuit, condenser fan relay, ECT sensor or oil temp sensor, but since
my AC quit working a long time ago, I have another question. I have
over 300K on the car and have no desire to ever fix the AC. The
million dolar question is, if I disable the AC do I really need the
condenser fan ? The helms manual shows only the radiator fan triggered
by the ECT for US or Canadian Integras w/o AC. This fan works
perfectly and the car has never overheated. Since it's the middle of
the winter and I don't want to risk draining my battery, I have
disconnected the fan at the green connector closest to the fan. Am I
risking overheating my car by disconnecting this fan ? I strongly
suspect the timer circuit has failed since I switched the radiator and
condenser fan relays and the problem persists. The timer circuit is
~$140 at Acura and I don't want to waste the money if I never plan on
fixing the AC. This car has over 300K miles and to make it worth
keeping, I need to choose my battles very carefully. Lots of little
things have failed on the car, most of which I or my local honda guru
fixed with junker parts, but it still runs great, original engine and
tranny. It's a great second car.

Thanks much, Sean

 

Nope. The condenser fan is solely for the A/C. Disconnect it and sleep
well.

 

I'd like to add that rather than disconnecting wires at the fan, I'd
just remove the relay for the condenser fan. That way you don't have any
loose wires that can get caught in moving parts or cause shorts.
