Re: the ac fan stays on with the key off
You are on the right path, this sounds like the resistor is bad and keeping your fan on, the resistor is located on the passengerside under the dash bolted to the heaterbox next to blowermotor,also the correct name for this is fan control module,heres a diagram to help you it show the module inside car, hope this helps.

only the HL and parking work , key off.
find what lamps glow, key off.??
there are lots of interiour lamps.
dash park lamps
dash warning lamps
foot lamps. lots more,. name some.
with keys in pocket, and HL and park switch off.
best is to do this in the dark.
and thus the name Dark current. (or phantom drains.)
Sounds like a supply problem ,the connections in the fuse board or the supply from the battery are corroded causing a high resistance and when the fan is turned on this causes a power drop thats allowing the fuel shut off or stop valve from staying open causing the engine to stop as its a diesel .Us old fleet vehicle fitters never die we just answer questions on here because the back breaking hard work of keeping the drivers on the road kills us off
There was probably a short somewhere in the electrical system for your fan that was causing a fuse to blow. I'm sorry, but it will not be an easy fix. You will need a wiring schematic (from a haynes manual from autozone) of this system, a multimeter and a free saturday. Disconnect the battery. Secure the black lead from the meter to a ground point on your car. turn the multimeter to the lowest Ohms setting. Then using the meter and the wiring diagram, find all the points where power and ground have close to zero ohms. A good place to start is the switch.
ok...this is an interesting problem...as you have electric fans.....one is for the radiator (cooling system) and one is for the a/c system. The radiator one will sometimes stay on after the engine has stopped and the key is out of the ignition, due to superheating ( a condition where the temperature of the coolant spikes after it stops being circulated around the engine) and will continue for a couple of minutes in the hotter weather.
But, considering it stops when you put the brake on...???? this definetly sounds like a short to me, and this together with the battery going flat...defineite short....
If you have got little experience in automotive electrical, I suggest you take it to a specialised repair shop to at least diagnose it.
I hope this helps you...\

Sounds like the fan control knob has shorted out. You can check the fan "blower" relay and fuse in the engine compartment but you need to make sure the control knob is good or you will keep blowing fuses and relays. If your blower fuse and relay are good, then just have the control knob checked and replaced if needed.
