Sometimes my front ac blower will not blow at all, and will blow sometimes. When it does blow it makes a noises.

And some times it will only blow ant very low speeds. Any ideas? Could it be just the resister and or the motor itself?

How do you replace the motor? The resister is easy.

Thanks, jason

remove the resistor and see if there is a huge mouse nest in the blower. There is all kinds of blower motor removal threads on here.

 

I cant find it, could you post a link on how to replace the blower motor


thanks jason

 

REMOVAL

WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in an accidental airbag deployment and possible personal injury or death.
NOTE: The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.

1. Disconnect and isolate the negative battery cable.
2. Remove the passenger side cowl trim panel (Refer to 23 - BODY/INTERIOR/COWL TRIM - REMOVAL).
3. Position the carpet to access the front upper screw that secures the air inlet housing (Lower Air Inlet Housing).
4. Remove the recirculation door actuator (Refer to 24 - HEATING & AIR CONDITIONING/CONTROLS - FRONT/RECIRCULATION DOOR ACTUATOR - REMOVAL).
5. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.
6. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
7. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and the lower HVAC housing.
8. Push the rubber grommet through the opening in the lower air inlet housing (Blower Motor Wire Lead Grommet).
9. Route the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
10. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing (Blower Motor Mounting Tabs).
11. Gently flex the recirculation-air door downward to gain access to remove the blower motor from the HVAC housing. NOTE: To aid in installation, note the position of the blower motor mounting tabs prior to removal.
12. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as necessary .

the cover that the recirc door actuator attaches to is what you are removing. There is one screw that is up against the fire wall and you can't access it unless you remove the hvac housing. You have to break the tab off the cover in order to remove it. After you have all of the other screws out, push the recirc door pivot up through the bottom of the cover. Grab the cover and kind of twist it back and forth until the tab breaks off.
