Front fan motor A/C - heater doesn't blow. Rear works fine on both. Replaced resistor and fan motor has power. Can't find front relay in fuse box.

Sounds like high blower relay is bad

I would have to say it's the switch on the console, possibly the wiring from the switch to the relay maybe?

Yes ,Or it could be the blower motor is burnt out,

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

check under your dash by the fuse box might be there

more than likely....blower motor resistor, normally located next to blower motor passenger
side under dash 2 screws & a plug

check the switch most used part usualy wears out if you know there is no power at the fan motor wires yes the twisted wires, then i would look at switch next.

The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?

I have a 2001 Black Durango that had the same problem. There is a resister to the right of the ac/heat blower (underneath the dash on passaenger side). This needs to be replaced. You might want to replace the motor as well. Both are real easy. I had replaced the resister first and everthing worked fine for about 6 months and then my ac/heat would only works on high. I replaced the motor and now it works just fine. The resister was about $15 at dealership and the motor is prob around $40-$50. I hopes this helps. Good Luck!
