You need a blower resistor and now a possible blower motor. # 4 is straight 12 volt power even when resistor is bad it works that's why I think you need both

SOURCE: freelander heater switch 1997

the fan works at different speeds by switching to a different resister for the given speed. A common fault is the resister pack has a thermal overload/cutout which over time corrosion sets in and it breaks down. When you find the pack [normally under bonnet and in the motor cowling ]although not necessarily, you will see agroup of wires 4/5 remove the pack locate the thermal cutout ,bridge it and test ,if the fan works on all speeds #replace the unit# , we don't want a fire do we??. the information that i have supplied is for general electrical principles , and unless your freelander has computor controlled heating the principles will be the same. if it is computor controlled it could get expensive .Good luck i hope that i have helped in some way. Pat.

SOURCE: heater fan switch only works on 4. nothing on 1-2 or 3

Most likely the blower motor resistor has failed. GM offers an updated version.

SOURCE: heater blower not working on seting 1 2 or 3 but

You'll need to check the voltage coming out of the switch. If it proves to be okay than you'll have to replace the resistor block in the heater box, this is a small rectangular black plastic plate with four wires connecting to it. It should be located under the hood on the passenger side firewall. Remove the two 5/16ths retaing screws and remove the block. To replace reverse the order given here. Thank you, Dana

The lower speeds are accomplished by running the power supply through various resistors that drop the voltage which makes the blower turn at different speeds. The lowest setting uses all the resistors to drop the voltage as much as possible to turn the blower as slow as possible. High speed uses no resistors so the blower gets full power and turns as fast as possible.

Since speed 1 and speed 2 use the speed 3 resistor to drop there voltage and speed three is not working as well my guess is the speed three resistor is burnt out in the device referred to as the blower motor resistor or blower motor speed control module. This is located near the blower motor and is held in place with 2 screws. There will be several wires and possibly two connectors plugged into it.

These are really common failures in many vehicles. The parts are usually available at your local auto parts store and they are typically not that expensive.

Hope that helped.

The heater only blows cold air,the radiator is full,thermastat is working and the engine temp is within normal ranges.


I've had this problem. 2000 GMC uses a closed coolant system. Meaning takes and returns coolant from and to the Reserve Bottle and has little air in the engine and heater systems.
If everything appears ok but no heat. "Air Lock" is the most likely cause. (With interior heater set to full heat) Solution; 1. Make sure water pump works. 2. Drain about 1/2 engine coolant into container. 3 Remove both heater hoses from engine side and flush heater core in both directs through heater hoses with garden hose. 4. Reattach heater hoses in correct locations. 4. Refill engine with coolant. 5 Start engine and run for 2 min., use caution when topping up coolant.
6. Most 2000 GMC have twist off caps with plugs located mid way on heater hoses. with engine cold, start engine these caps may be loosened to allow trapped air to escape. Do not attempt with engine hot due to hot coolant injuries. This may take more than one attempt to remove all air from heat system. 7. Lastly most 2000 GMC water pumps have a bleeder plug,( 3/8" square driver plug) located on the water pump. With egine cold this plug should be removed to remove any air. Reinstall plug with thread sealant.
Hope this helps cheers

Heater only works on 3 and 4 setting


Your heater motor speed selector only working on a couple levels is caused by a faulting blower motor resistor.This part is located on the evaporator case next to the blower motor itself.Two bolts remove the resistor and an electrical pigtail finishes it off.The location of this is underneath the dash on the pass front side.Happy Holidays!!
