These resistor modules often fail from heat stress that can melt plastic connectors.

Why is the blower motor running at a low speed?

Be careful, on some vehicles when the engine is running the interior fan is in constant operation at a low speed. GM called this astro ventilation. This is to provide an ample supply of fresh air in the interior compartment even when no climate control mode is selected.

What causes a Nissan blower motor to run slower?

The auto AC regulates the fan control amp, which regulates the voltage to the blower motor. A low speed setting causes a lower voltage across the blower motor, which makes the motor operate slower. At maximum fan speed setting, the fan control amp allows nearly all 12v across the motor, which causes the fan to run faster.

What causes a blower motor to stop working?

In a situation where the motor doesn’t work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. Blower motors generally don’t fail out of the clear blue.

How do you fix a blower motor on a car?

Disconnect the electrical connector at the blower motor and jumper power and ground to the motor, bypassing all the speeds controls. Run a fused jumper from the battery to the power side of the motor and connect a temporary grounding jumper to the other motor terminal.

What does a blower motor do in an air conditioner?

What Is a Blower Motor? The blower motor is a component in your HVAC system that blows the conditioned air through the vents in your home. It takes the cool air created by your air-conditioner and circulates it throughout your indoor space to ensure that the temperature reaches the level dictated by the thermostat.

Why is my Mercedes Benz blower motor not working?

If there no power is found, the blower motor resister is the culprit and needs to be replaced. As a note, 85 percent of the time when the blower motor does not come on or operates at one speed only, the blower motor resister is at fault. The resister emits substantial heat from the resistance it supplies and eventually burns up.

Furnace or AC Blower Motor Not Starting or Working! Top 10 Reasons Why! – YouTube If playback doesn’t begin shortly, try restarting your device.

What does it mean when your AC fuse keeps blowing?

Yes, that means that your current is slightly over the rating of the fuse. Fuses have a delay so they don’t trip immediately on a small overcurrent. The fuse trips proportionately faster the larger the overcurrent. Nonetheless you are exceeding the sustained rating of that circuit.

What should I do if my car fuse keeps blowing?

If the A.C. fuse on your car keeps blowing, I’ll start by stating do NOT install a larger fuse. The fuse is a protection device, and there is a problem in that particular circuit. That problem needs to be corrected before installing yet another fuse. Step one is to determine EXACTLY what is on the circuit for that particular fuse.

What happens when the AC relay goes bad?

When a relay is starting to fail, it may give weakened or intermittent power to the compressor, which will result in weakened or intermittent function of the AC. The AC may function fine in one instance, and then shut off, or deliver inconsistent performance in another.

Most likely it’s the blower motor control module. It’s the equivalent of the resistors that are in manual heater control cars in the old days. It sits on top of the box near the blower motor. You have to loosen the one or two bolts holding the relay center that’s above the heater box there to get it out of the way.

Why does my Pontiac Bonneville have low coolant?

Open the cap, when COOL, and look. Low coolant means the heater core gets an air bubble–air doesn’t transfer heat. If it is low, fill. Run car until fully hot and speed up motor to 2500 for a few seconds and repeat this 5 times to push water into heater core and get the air bubble out.

How does an air conditioner blower fan work?

The blower fan in your air conditioning is a separate electrical system from the cooling unit. However, they work together as a team. As the air conditioning system cools down, the blower fan pulls the warm air from inside of your home, runs it through the air conditioning system, and then blows the now cool air back out into your home.
