Will a blower motor work without the resistor?

Without any power, the motor won't run. As a result, the blower fan stays still and silent, and no air blows out of the vents. There are instances where a bad resistor will prevent the current from reaching the blower motor altogether.

What causes blower motor resistor failure?

In most cases, the blower fan resistor is failing either due to overheating or corrosion. If the blower fan fails, your car will not blow any forced air. However, sometimes the problem can be with the blower motor itself. This is especially apparent when you have replaced the blower fan multiple times.

What does the blower motor resistor do?

1. Strength Off

Make sure the power is off at the breaker prior to starting and use a voltage tester to verify that wires and/or electrical contacts are completely lifeless before you start working on them. Make sure everyone in your home is aware that electrical work is going on. Tape the circuit breaker into the off position.

2. Be Careful What You Touch

Never touch plumbing or fuel pipes while working together with electricity they are often used to ground electrical systems.

3. Use The Right Tools

Before you begin, be sure you have an idea in place as to what outlets, switches and fixtures will be involved in your project. Create sure you have all the appropriate tools, including but not limited to: needlenose pliers, wire blades, cable & wire stripper, fish & colored tape, volts tester, continuity specialist, electric & rightangle drill.

4. Purchase the Right Parts

If you are installing new receptacles make sure the new ones match the wiring in your home. A AL-CU stamps means it can be used on aluminum and copper wiring. When it is unmarked or you will find a reduce through the 'S if should only be used on copper wiring.

5. Add a Junction Box

Never splice wire connections together and hide them within a wall with no verse box — an accessible junction package should always be used to become a member of wires.
