Learn the Step by Step Instructions to Change a Blower Motor Resistor
The blower motor resistor is kind of a tool wherein it is a car's warming and air conditioning unit controls the fan speeds. There are two different types of blue motor resistor; the resistor wire types that utilize an alternate size coil of wire for each one fan speed with distinctive resistances and the printed circuit board with a completely incorporated circuit. The two units are placed in the same area, which is in the immediate closure of the blown engine. They are dependably a little unit, generally 2 inches by 3 inches. The principal unit, which is the arrangement of distinctive size loops, is mounted on a little level non-conductive plate and the second have a circuit board on a plastic base plate.

Read the step by step instructions to change a blower motor resistor:
Locate where the blower motor is place and look around the outside and near the engine for a2 by 3 inch plate hung on by two or four little screws. You will notice that there will be an electrical connector connected to it with a five or it can be six wires, contingent upon the vehicle type and warming and air conditioning kind of a control panel.
Check and test the resistor of your vehicle before you replacing it. Remember that it is constantly proposed to test any electronic unit before supplanting in light of the fact that there are a huge number of things that could result in the same indications. It only takes a couple of minutes and can qualify the assumption that a part is terrible. It will save money to replace or repair the right part the first run through.
Test the speeds of your vehicle by turning the blower or fan control to all different positions. Observe and remember which fan speeds are working and not working. If the fan of your vehicle only functions only on one speed the blower motor resistor is so likely bad.
Check and observe if the fuses of your fan speeds are working or not. The fuses for the inside of your vehicle warming and air conditioning fan are normally under the hood in the wire and the relay center. Check to verify that there is voltage to the circuit. If not, check for an open circuit to the breaker.
Take a look for the relay to determine if there is a power place into the fuse. The relay should have two of the four terminals appearing. With the key on and the fan turned on, evacuate the hand-off and set it back in, listening for it to click. On the off chance that it doesn't click, then supplant the hand-off.
For the final step, check the voltage locates at the electrical connector on the blower motor resistor to observe if the fuse and relay are both good. Ensuring that the power is near at the connector with the key on and the fan is switched on.
