Blower not operating

Many vehicles that have both front and rear A/C systems utilize two blower motors; one for the front vents and one for the rear vents. Each blower motor also likely has its own dedicated blower motor resistor to enable independent airflow control. The most common failure items in blower motor circuits are the blower motor and resistor. When a blower motor fails it will not work on any speed setting. Blower motor resistors however, tend to maintain proper operation on HIGH speed but none of the lower speeds; this is not always the case though. Proper diagnosis begins with checking for power at the blower motor. If power is present, the blower motor has likely failed. If no power is present, the blower motor resistor should be checked for power. If power input is present but no output, the resistor has failed. If there is no power input, the fuse should be checked as either one of the component failures could have caused it to blow. After replacing the fuse the same checks should be made again to determine where the power flow stops and why.

Removal

1. Remove wiper arms.
2. Remove cowl panel.
3. Disconnect blower motor electrical connector and vent tube.
4. Remove blower motor retaining screws.

1. Remove fan retaining nut from blower shaft through plenum opening while holding the fan from the engine compartment.
2. Remove fan from blower motor while removing blower motor from vehicle.

Installation

1. Hold fan through plenum opening.
2. Install blower motor to vehicle while installing fan to blower motor.
3. Install fan retaining nut to blower motor shaft through plenum opening.
4. Install blower motor retaining screws.
5. Connect electrical connector and vent tube.
6. Install cowl panel.
7. Install wiper arms.

If the blower is not producing a strong flow of air, something has to be restricting it. Or something simple like the blower cage is slipping on the motor shaft.
You disassembled the HVAC box, are you sure the heater core or evaporator is not stopped up? Or the intake vent ?

If you are talking about the blower for the heat and ac, someone needs to check the blower for voltage and ground, also the blower relay and the resistor as needed.

replace the cabin air filters

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

possible ignition switch, also need to check ground wire to terminal G200

on the front blower make sure the fuse is ok if it is then check the relay if its good as well then youll ned to replace the blower motor. as far as the rear it sounds as if the air handler is not operating properly you need to locate it and ensure that nothing is blocking it from turning.hopes this helps you.

Get a new blower motor and relay.

Sounds like the blower motor resistor is bad. These things go bad all the time. and for the switching modes there is a vacuum line that runs under the window in the engine compartment and runs by the alternator, its tiny and may take a few minutes to find. check first by the evaporator case and follow it by the alternator to the driverside of the throttle body. these too break and will not allow the heater mode changes. the blower motor resistor controls the fan speeds and the vacuum line allows which vent the air flow goes through.
