My heater blowers dnt work and i need to knw where i can locate the resister blocks for my heater blowers so i can ghange them

Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

For blower motor testing and replacing, check the link below: ----

The fan wont come on when i turn the ac/heater on

Hi,
Common issue is the 'blower resistor' going out. You can usually buy the part @ an auto parts store or @ the dealer. The dealer should know where it's located - I do not.

Some times, you have to replace the entire blower motor. View this LINK for info.

GL,

The fan on my dashboard is not working. I am thinking of replacing it with a used one from a junk yard except I dont know where is located.

it's behind the glove box. here are procedures from autozone.com:

CAUTION The Supplemental Inflatable Restraint (SIR) system must be disarmed before removing the blower motor assembly. Failure to do so may cause accidental deployment of the air bag, resulting in unnecessary SIR system repairs and/or personal injury.
  • Disconnect and isolate the negative battery cable, then wait 2 minutes before proceeding with the removal. This will effectively disable the air bag system preventing possible personal injury.
Remove the glove box from the instrument panel.

  • Remove the A/C-heater blower motor cover.
  • Disconnect the blower motor wiring connector.
  • Remove the blower motor wiring grommet and feed the wiring through the blower motor housing.
Remove the blower motor mounting screws.

Fig. The blower motor is secured to the housing with three small screws


Allow the blower motor assembly to drop downward to clear the instrument panel and remove from vehicle.


To install:

  1. Place the blower motor assembly into position on the A/C-heater unit and tighten the mounting screws.
  2. Route the blower motor wiring through the blower motor housing and seat the wiring grommet in the hole of the blower motor housing.
  3. Reconnect the blower motor electrical connector.
  4. Install the A/C-heater blower motor cover.
  5. Install the glove box into the instrument panel.
  6. Reconnect the negative battery cable. Check blower motor operation.

1998 Ford Contour. The heater blower stopped suddenly. I checked all the fuses, good. I removed the blower and hooked it to 12 volts. Whoosh! It almost spun out of my hand. I checked the plug into the...

I dont know what these other guys are saying..I think they snif the glue!!! YOUR BLOWER FAN ASSEMBLY CAN EASILY BE REMOVED !!
1. Remove the wire
2.Find the "tab on the housing and pull it down while rotating the fan housing counter clockwise. This will remove the fan assembly. Plage 12 volts on the contacts to test the motor. If it works then the resister pack is blown. On the fan housing (near firewall ) you will see a plug going into a square looking box with a screw in it. Remove the wire then remove the screw to remove the resistor pack.. A new resistor pack is around 20 dollars at a ford dealer. Hope thie "FREE" info helps!

Blower only works on 4,123 not working.

Hi There;
You say your heater fan only works on high.

This issue can be repaired by replacing what is called the "blower motor resistor". The electrical current flows through this unit in all positions except #4.
If you look under the dash on the passenger side with the heater fan on #4 you will hear the blower motor running. Just slightly toward the drivers side of the blower motor & closer to the firewall you will see a four wire connector. this is attached to the "blower motor resistor". If you get a replacement one & examine it you will see two screw holes where you will need to remove the 9/32nds screws from the one in your truck to remove the fauly one & install your new on. This part is relitivly inexpensive & it is not worth trying to locate a used one.
Please let me know if you need more info on this
Farrout!
