Blower motor will not come on (has climate control) checked fuse what about relay or resistor and where is it located?

Heater not working ???? Blower motor not working , no air blowing out of the vent's. defrost , floor ? I'm assuming you have the manual HVAC - climate control system , by the fact that you replaced the resistor assembly . Was there a relay included on the resistor assembly ? What fuse's did you replace ? HTR/AC - 30 amp. left I/P fuse box , BLOWER fuse -40 amp - under hood fuse box ? Did you use a DMM - digital multi-meter an test for B+ voltage at the purple wire at the blower motor ? The fuse's you replaced ,check for B+ voltage with meter .
Your vehicle could have two different HVAC systems , manual & automatic. The automatic system doesn't have a resistor assembly , has a blower motor control processor. Do you know how to test automotive electrical circuit's ?

Manual or automatic climate control ? If it is a manual system the relay would be near the blower motor in the blower motor resistor assembly . This is behind the glove box .
If it is automatic system it doesn't have any relay's has blower motor control processor .

Manual or automatic climate control ? Which orange wire . There are two . Blower motor relay for high speed . FRT/ HVAC fuse 30 amp located in the under hood fuse/relay box . HTR-A/C fuse 25amp. located in the left I/P fuse box .

This vehicle doesn't have a blower motor resistor ! It has a blower motor control module , if you have automatic climate control !
If manual climate control , then there is a blower motor resistor assembly !
Blower Motor Control Processor The blower motor control processor controls the speed of the blower motor by increasing or decreasing the voltage drop on the ground side of the blower motor. The HVAC control module provides a low side pulse width modulated signal to the blower motor control processor over the blower motor speed control circuit. As the requested blower speed increases, the HVAC control module increases the amount of time that the speed signal is modulated to ground. As the requested blower speed decreases, the HVAC control module decreases the amount of time that the signal is modulated to ground.
Air Speed - Front Control
The blower motor forces outside air into the vehicle's interior. The vehicle operator determines the blower motor's speed when the driver places the blower switch in one of 5 blower speeds. The blower motor will always operate in any switch position other than OFF, as long as the ignition switch is in the RUN position. The blower motor and mode switches are located within the HVAC control module. The blower motor OFF input is connected in series with the HVAC control module by the off blower motor control circuit.
Depending upon the selected speed, power is provided to the blower motor from either the ignition 3 voltage or battery positive voltage circuits from the fuse block. The battery positive voltage circuit only provides power when the High blower switch position is selected. Power and ground are provided to the HVAC control module by the ignition 3 voltage and the ground circuits.
Low Blower Speed When the Low 1 blower speed is selected, the HVAC control module applies voltage to the blower motor resistor assembly through the low blower motor control circuit. Voltage is divided between 4 series resistors, a blower relay, and the blower motor to achieve the desired blower speed. The blower motor is grounded through the ground circuit.
Medium Blower Speeds When the Medium 1 blower speed is selected, the HVAC control module applies voltage to the blower motor resistor assembly through the medium 1 blower motor control circuit. Voltage is divided between 3 series resistors, a blower relay, and the blower motor to achieve the desired blower speed. The blower motor is grounded through the ground circuit.
When the Medium 2 blower speed is selected, the HVAC control module applies voltage to the blower motor resistor assembly through the medium 2 blower motor control circuit. Voltage is divided between 2 series resistors, a blower relay, and the blower motor to achieve the desired blower speed. The blower motor is grounded through the ground circuit.
When the Medium 3 blower speed is selected, the HVAC control module applies voltage to the blower motor resistor assembly through the medium 3 blower motor control circuit. Voltage is divided between a series resistor, a blower relay, and the blower motor to achieve the desired blower speed. The blower motor is grounded through the ground circuit.
High Blower Speed When the High blower speed is selected, the HVAC control module applies voltage to the blower motor resistor assembly through the high blower motor control circuit. The voltage energizes the blower relay, causing the blower motor to be connected directly to the battery positive voltage circuit. The blower motor and blower motor relay are grounded through the ground circuit.

Chevy Trailblazer EXT Blower Motor Won Turn Off

fuse in fuse box, relay and resistor located on fire wall next to blower motor. strong possible resistor is bad

Test for current to motor. If none you have either a bad fuse, bad switch or bad wiring. Nothing else left.

• REMOVAL & INSTALLATION

Print

Fig. Fig. 1 Blower resistor assembly is underneath the fuse block

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Remove the rear sight shield.
3. Remove the fuse/relay block assembly and bracket.
4. Disconnect the resistor module connector.
5. Remove the retaining screws and remove the resistor module.

To install:

1. Inspect the gasket and replace or repair as required.
2. Install the resistor module and secure with screws.
3. Connect the resistor module connector.
4. Install the bracket and fuse/relay block assembly. Install the sight shield.
5. Connect the negative battery cable, and check the climate control system for proper operation

When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

blower motor resistor

There are 2 relays for the blower. The low blower relay and the high blower relay. They are both located
under the hood in the center of the firewall.
The low will have 4 wires from it, one lt. blue and 3 brown. The high will have 5 wires 1 purple(to blower mtr.) 1 black 1 dk blue 1 red and 1 orange.
Also, the blower resistor is in the same area if needed. Hope this helps.
