Which fuse controls the heater fan - 2002 Cadillac Deville

• engine dead?
• car can not drive.?
• battery dead
• fuse blown
• starter dead
• jumper cable starts work?

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.

Check fuse and relay as mentions in the link. Also the BCM is involved with climate control in which case you will need an auto electrician with a pro grade scan tool computer.

Yes it's the heater relay. There is no power activating your relay
Replace it

There is a resistor pack that controls the fan speed switches. Not sure about the 2000 Disco but on Range rovers of that era it is under the cover below the decker panel.- namely at the rear of the bonnet. Check that it actually is there, then get back to me and I'll post details of how to replace it

Yes, the heater fan does have a fuse. If the fuse isn't blown, there's a sensor in the duct work behind the glove box under the dash that controls the fan speeds that you can check.

Check heater fuse.
If fuse good - could be a failure of the blower fan motor or blower control switch.
If fuse bad - bad blower fan motor could have blown the fuse.
DO: check fuse, then blower motor.
Pricing: new blower motor: Duralast PM270 $43.99
new heater control switch: Duralast SW229 $46.99 (without
A/C).
I'd expect your blower resistor to be good - when they fail, the blower only will work on HIGH setting.

The fuse for heater/ac fan is number 36.30 amp located end of dash
If this is ok,you need to replace heater control module behind heater controls.Save money buy haynes manual,check e bay

it could be the fan motor, the resistors that control the speed or the switch as well as a loose wire

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.
