you heater fan switch is most likely bad. that whole panel will need replacement just to get the fan switch. been there,with all the trouble to get it out,suggest you replace new, not used. hope this helps, and i just had another thought on the subject while i'm here i might has well try another solution. has anyone spilled coffee or a soft drink,even a couple drips will seep down into that switch. i've cleaned them before and had a few sucesses.you'll need an electrical component spray cleaner. try spraying it around that fan switch,let it dry,then try fan switch again. sometimes it does work thank you for choosing fixya.com
Usually what happens is the switch goes bad and starts sending multiple current paths to the resistor. Then the resistor pack burns up as well. There is some detailed discussion on this at http://www.fixya.com/cars/t5072781-location_blower_motor_relay
replace the blower motor resistor located on the heater box were the blower motor is located the wiring to the blower may go to it. This is very easy to locate if you buy the part first.
no this is not a thermo issue the heater controls are bad and need to be replaced ive seen this alot in general motor trucks and cars.thanks and good luck
Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller
there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate
