Question about 2004 Ford F-250 Super Duty

1 Answer

AC Heater When I turn on the ac heater control at any speed it makes a rumbling noise and does not blow air. I replaced the ac heater blower moter thinking it may be that but it is still making the same noise and not blowing. It also began to smoke out the vents for a few seconds but I turned it off. Any ideas would be appreciated.

It sound like the blower wheel of the blower motor is rubbing the inside of the housing (the smoke). Sounds like the blower wheel rubbing may have burned the inner plastic housing or has come off of the motor shaft inside. Take the blower motor and wheel back out and inspect everything closely I think you will find the problem.

SOURCE: Temperature Control not working on 1999 Ford Explorer

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

Trouble shot heater switch and blower moter


You don't give much info, so it's hard to give you a good answer. Do you have power up to the heater switch and after turning the heater switch to the on position do you have power to the blower? Did you check the fuses, do you have power on both sides of the fuse? if you do follow that wire and check for power at the other end of it. Some cars have a temperature sensor and the blower will not come on until the temp. is warm enough so that the blower will not blow cold air. If you track the hot lead from the fuse box to the switch, through the switch and to the blower and at any point find you no longer have power, that would be the component I would think is causing your problem. You can also check the blower by running a test lead from the positive side of the battery to the blower motor and see if it runs.

Ac/heater works but doesn't blow air at any speed


Yes. It could be your motor. If there is voltage or your hear the motor running then it could be a vent door not working. There is also the switch and a blower motor resistor that you can check. Hope this helps.

Blower speed question (ac/heater). This just


This is definitely 100% the Blower Motor Resistor.
Replace this and all speeds will work fine.
This Resistor is defined with 3 to 4 wires going into it, and is located adjacent to the Blower Motor.
It is easily access, removed and replaced.
I will post an additional comment on Part Number, Price and where available.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Ac/heater blower fan does not work


Several possible causes (blown fuse, malfunction in blower speed switch, open ground in blower motor electical circuit, burned out blower motor (brushes), open circuit in blower resistor, etc. Best solution, Take the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.)

AC N MY CAR


Brushes on the motor may be going bad. Blower motor is in engine compartment under wiper motor assembly. The blower motor regulator is under the blower motor. There is an A/C relay behind the fuse box under the screwed down cover.
for lack of motor speed its probably the brushes on the motor or the regulator. If no cold air your charge is probably to low to engage the compressor.
