I would check ur blower resistor by the blower, idk if u had other problems before this like the blower only working on certain speeds but, but your problem could be the ignition switch and cylinder could be the contacts are keeping in run position
replaced ac and heater blower motor relay, because it will not switch off power to blower motor causing blower motor keep running and pull down the battery.
if you are talking about the engine electric cooling fan..it will run after car is turned off until temp goes down then it shut off..unless you're talking about the heater blower motor..then i would look in the engine compartment passenger side firewall for the heater box ..on the box there is speed control resistor for the heater fan speed..that might be shorted.if not fan switch on dash..give more info next time..it makes it easier answer with more info
FIRST CHECK HVAC FUSE AND BLOWER MOTOR FUSE AND RELAY.IF BOTH CHECK OUT OKAY PROBLEM COULD BE HVAC CONTROL SWITCH OR MODULE OR THE BLOWER MOTOR IS BAD.TO KEEP FROM SPENDING ALOT OF MONEY.THE HVAC CONTROL MODULE CONTROL SWITCH VERY EXPENSIVE.IT COULD COST $300.00 TO $400.00 DOLLARS.WHAT I WOULD DO IS REMOVE BLOWER MOTOR IN THE LEFT REAR TRIM PANEL.HOT WIRE TO BATTERY USING JUMPER WIRES.IF BLOWER MOTOR RUNS ITS THE HVAC SWITCH.IF BLOWER MOTOR DONT RUN REPLACE IT.IF THE HVAC IS BAD BEST FOR DEALERSHIP TO CHECK IT OUT.BECAUSE YOUR DASH HAS AIR BAGS IN IT. WHICH WOULD BE DANGEROUS.
HAVE BATTERY VOLTAGE CHECKED.MAKE SURE BATTERY IS FULLY CHARGED IT SHOULD BE 12.5 VOLTS.IF YOU HAVE DIM TURN SIGNAL LIGHTS.EITHER YOU HAVE WRONG BULBS OR POOR GROUND ALSO THE WEAK BATTERY OR UNDERCHARGING PROBLEMS HAVE ALTERNATOR CHECK OUT. FOR THE BLOWER MOTOR.CHECK FUSE AND RELAY. IF BOTH GOOD YOU HAVE A FAULTY AC + HEATER CONTROL SWITCH.OR THE BLOWER MOTOR IS FAULTY.REMOVE BLOWER MOTOR HOT WIRE IT USING A JUMPER WIRE TO BATTERY.IF IT RUN YOU HAVE SWITCH OR WIRES TO SWITCH PROBLEMS. IF BLOWER MOTOR DONT RUN.REPLACE IT AND BLOWER MOTOR RESISTOR.NOW IF WIPERS KEEP WORKING WHEN YOU TURN THEM OFF.YOU HAVE A FAULTY SWITCH OR DEFECTIVE LIMIT SWITCH IN THE MOTOR.
are you talking about the fan blower inside the car or the fans under the bonnet..?
the fans under the bonnet may stay on for a while after the engine is switched off to prevent heatsoak. This is when the engine actually heats up more after switch off due to latent heat within the engine. The fans will remain on until the coolant temperature has fallen and stabilised, then the fans will stop. If the blower fan inside the car keeps running, this may be a feature on the car to assist with heat soak but I would think this is more like a faulty power relay or fan controller if the car has climate control..In this case, my advice would be to consult a qualified autoelectrician.
it's either the blower motor switch or blower motor resister.
