There are many ways to test a resistor, but the most easiest and basic method is to check the voltage at the electrical connector on the blower motor with a multimeter. However, if the resistor has burned out due to overheating, the blower motor may cease to function. Yes, the blower motor can still be operative after the resistor goes bad, but it may only work at high speed, or remain stuck at one fan speed. Will a blower motor work if the resistor is bad? Therefore it is generally recommended to replace the old blower motor in Trax as well when replacing the resistor. What causes blower motor resistor to fail in Trax?Ī struggling blower motor due to internal component degradation can put a lot of strain on the resistor when in operation, causing it to overheat and burnout. The resistor is typically located under the passenger side dashboard, near the blower motor. If the resistor module develops a fault, it can cause the blower motor to stop working. When you increase or decrease the AC fan speed in your Trax, the climate control unit signals the resistor module to increase or decrease the flow of electric current to the blower motor. The function of the blower motor resistor is to control the speed of the blower motor.
Note: Vehicles with auto climate control may not have a blower motor relay. But before you begin the replacement, it is highly recommended to disconnect the vehicle’s battery. You can test the relay by swapping it with other relays in the fuse box with similar amp rating. If you are lucky, the wiring diagram will be drawn on the facing. Typically relays are located in the engine compartment or under the steering wheel on the left-hand side. The information may be listed in your vehicle’s owners manual. A bad relay can also be the cause of AC blower motor failure in your Chevy Trax.įirst of all, you should find out where the blower motor relay is located in your particular model of Trax. Relays are electromagnetic switches that are used to switch electrical loads on and off. It does not matter in which direction you insert the fuse. You must replace it with one of the same amperage and therefore the same color.
If the metal strip is broken in the middle, the fuse has blown. To check the fuse, pull it out of the fuse box using a fuse puller or needle nose plier and hold it against the light. If the fuse is blown, replace it with a new one with the specified amp rating.

In case of a faulty fuse, the circuit is interrupted and the motor can not work.Ĭheck the owners manual of your Trax or the fuse box cover to find the exact location of the fuse for the blower motor. The AC blower motor in Chevy Trax needs electricity to work.
