During the colder parts of the month, you will start to rely more and more on your car’s heater. With all of the different components that are in place to ensure...
Keeping the cabin of your car warm during the frigid temperatures of winter can be a lot easier said than done. If even one of the components of the heater are...
During the summer months, there is nothing more important to a car owner than a properly working air conditioner system. Most car owners are unaware about just how many components have...
The sun sets, and the air has a chill. You pause to flip your jacket collar up, and you walk briskly to your car door and slide into the driver's seat. Once...
Keeping the cabin of a car at the right temperature is no easy job. A number of components have to work together in order for your car’s cabin to stay comfortable....
Vehicles that are equipped with a manual HVAC, or climate control, system utilize a blower motor resistor to control the speed of the heater blower. If you are driving a minivan or...
The heater blower motor is part of the air conditioner and heater controls assembly, one of the many features created to make your ride as comfortable as possible. Your heater and air...
The stalling could be due to a heat induced failure of the ignition coil. Resistance of electrical components increases with temperature and if the coil is the issue that is why the stalling only occurs once the engine is hot....
It's possible the blower motor, or possibly just the blower resistor block, has failed. To determine which of these (or other) possibilities are involved, please request a fan/blower motor diagnostic and the responding certified mechanic will get this taken care...
Hello, thank you for writing in. There are a few more bits of information that we need to try and help guide you. If by not having air, you mean that the air stops blowing, then you have an issue...
The blower motor resistor, in the motor speed control circuit, is probably faulty. If your vehicle does not have automatic temperature control, the part that needs to be replaced is relatively inexpensive. If you desire a definitive diagnosis, and replacement...
Hello, thank you for writing in. If you have not resolve the issue(s) that caused the vehicle to overheat in the first place, then you need to start there. Do so by checking the level of your coolant, the radiator...
If you have Electronic Manual Temperature Control (EMTC), the blower motor resistor block is accessed by removing the accelerator pedal. Once the pedal is removed you will see the wiring harness to the block and the single retaining screw that...
If you are referring to lack of air flow, and not inadequate cooling, the problem is due to either a restriction in the vent network or a fault with the blower or blower circuit. Restrictions are usually due to blower...
In your application, there is a replaceable blower motor resistor block. The resistor block permits multi-speed operation of the fan. If some fan speed settings work, but not others, the first thing to do is test the resistor block with...
You must be using an aftermarket blower motor. You will need to cut off the old connector and using wire splices you will need to connect the wires to your connector. Before making final connection you will need to install...
There are two blower fuses. There is a low and a high blower fuse. You need to check the 20 amp low blower fuse in the fuse box to see if it is blown and has power with key in...
You might be right. A defective blower motor can draw too much current and take out a resistor. But a resistor can also overheat because it doesn't get enough airflow. Most blower resistors are set in a location where the...
Hello. It sounds like you have a voltage issue. When the power in the vehicle drops below a certain level these lights will come on as a warning. Since they come on when turning on the blower that means that...
Hi there - I believe the heater fan motor bearings are shot, and that's the noise you hear - increasing noise level as fan speed goes up. These bearings are generally not serviceable, and the fan motor should be replaced....
Hi Trevor: If I understand your posts correctly, you have installed a new blower motor, a new resistor block and you have tested the relay. Although you may have continuity throughout the circuit, if there is excessive voltage drop anywhere...
The only procedure that mechanics use to remove the blower is that set out in the Factory Service Manual (FSM) for your vehicle, which has a detailed, step-by-step procedure, with illustrations and diagrams, but those instructions vary quite a bit...
If you look under the right side of the dash to locate the blower motor for the a/c heater system and disconnect and inspect connector to blower motor and to the resistor. If both look good then you most likely...
If the blower motor is new, you'll want to first determine whether power is getting to the motor, and if there are any voltage drops (high resistances) in the circuit when the blower switch is in the on position. If...
What you are describing sounds like a failure of the blower motor that circulates air in the HVAC system, however, there are certain faults that could occur in the electric circuit that powers the blower motor. If power is reaching...
Hello - your symptoms suggest that the HVAC blower motor resistor has failed. The blower motor resistor limits fan motor speed for the Low and Medium settings, but is not involved at the Max setting. Since defrost on most cars...
Intermittent blower motor operation could be related to the switch, resistor block, fuse, relay, motor, or wiring. To resolve this, the recommended service is a blower motor circuit diagnostic during which a certified Mechanic, dispatched by YourMechanic right to your...
