It sounds like you may have a malfunctioning component in your heating system that is causing the fan to continue running even when the car is turned off. Pulling fuse 47, which controls the climate control blower and ignition 3 relay, stopped the fan from running but may have also caused other issues in the system. Replacing the fuse may not fix the problem, it may be necessary to have a mechanic diagnose and repair the specific component causing the issue.
So the fan is running with the key off and out of the switch? Is this the blower fan for the heater and AC, or is it an engine cooling fan? Either way, if a fan is on or if your engine coolant fan doesn't stop after one minute, then you really do have a problem. It will quickly drain the battery. You will have to look at a wiring diagram for your car's fan controls to see which way to go. There could be a relay or two involved. In the meantime, to save your battery you could pull that fuse out every time you turn off the car, or leave it out if the fan is not needed.
There are some fuses that are "hot at all times", so they would always have power to the fuse. One would just have to consult a wiring diagram.
Should have a fuse for it; look for 25 or 30 amp heater fuse. If it's good, pull off the connector at blower motor, and with key on and heater fan switch on high setting, check for power at the connector. If you have power there, then the motor nust be bad and need replacing. If no power at the motor, the switch may be bad, or the wiring or the heater relay needs to be investigated. Good luck.
Did you remember to replace the fuse?. So, the fan kept running even with the controls in the off position? Were there any other accessories that would run with the key turned off?
Blower is over the passenger's feet. Pull down insulating panel, and you should see it. Pull off connector and check for voltage in cable with ignition on and fan set to high--should be 12-13 volts. If you have voltage, replace motor. If not, troubleshoot fuses/relays, switch, and resistors.
Does fan come on even when heater is off ? Try it in heat mode, not defrost & see if it still stays on. If yes, you need to find the relay for the fan. There may be a few that look the same, but when you pull the right one out with key on you'll know as fan will stop. If fan stops, replace the relay.Check owners manual & fuse panel , as well as under hood.
