Fan turns on when car is off and drains the battery

[Forsaken]

Problem:

I've got a '91 Integra ls. When I shut the car off, the fan turns on and kills the battery. This problem seems to get worse when it's cold out. The car doesnt over-heat.

Ive been looking for a while and seen a bunch of different suggestions as to what it could be: temp. switch b, relay, cooling fan timer unit, etc. Most of what Ive seen has to do with the relay.

Anybody have any suggestions?

Temporary Solution:

Took the car to O'Riley auto parts. I told them what was going on. They came out and started pulling fuses (the fan was running while this was going on) until they found the fuse that shut the fan off. Turns out it was my AC condenser fan that was running the car till the battery was dead. Since its winter here, Im just leaving the fuse out until I'm forced to fix the real problem next summer.
