Hi can anyone help as my internal heater fan seems to stay on after I turn my ignition off and it keeps draining my battery!!!!!

Does anyone know what is causing this
 
Will take a guess at the control relay, the relay takes it's direct supply through a fuse from the battery and is only using the ignition supply through the sensor as a switch. I think the relay has locked on thus allowing the main supply voltage to keep the fan running as the fan will be permanently earthed.

Sorry but I have no idea where the relay would be located, so you may need to consult the manual. Good luck.
