Hi Can you please tell me why my blower fan runs on high for heater. I read some where it could be the blower resistor or the motor control speed unit. I also read it could be behind the glove compartment.I've never repaired my 2006 Ford Explorer before so any advice you can give me would be most appreciated.

Re: Blower fan runs high only on 2006 Ford Explorer
If you have manual control climate control then the system has a blower motor resistor . if you have automatic climate control then the system has a blower motor speed control. in eather case the part is under the dash in the heater box. depending on the system you have, buy the part and then look under the dash for like part, you will half to remove the under dash panels to be able to see. the part will be on the heater box somewhare.

You relay switch is stuck on. Replace it. Second thing to check is the fan switch may need to be replaced. If you turn off your engine and then back on does the heater fan go on even when it is turned off at the switch?
If this occurs in all positions, check fuse, check for power at the fan motor, if power in all positions replace motor. if no power at fan and fuse is good, check blower motor resistor and blower motor control switch. Replace as required
Look under the dash on passenger side and just to the left of the blower motor housing you will see the 4WD control module.Remove the 2 screws holding the module and let it hang down and your resistors are behind this.Remove the 2 screws holding the resistors and remove.
Now I am assuming you have manual climate control and not electonic.
if ur blower only came on the high fan speed i say it was ur blower resistor , but ur blower aint working at all so i would replace the blowerand the resistor cause they eventualy good out with when then the blower problems
