Why does my car blower motor not shut off?
If you have a vehicle with climate control system and a variable speed blower motor and the blower motor won’t shut off and stays on HIGH with the car turned off and the key out, chances are the blower motor motor control processor is toast or the HVAC control module is damaged.
What happens when a blower motor relay wears out?
Without it, the AC system will not be able to circulate any heated or cooled air. The blower motor relay controls the current used to power the blower motor, and is subject to the constant on and off switching. Over time, it can eventually wear out.
What are the symptoms of a bad blower motor resistor?
Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. If the blower motor resistors’ internal components fail it may cause the blower motor to malfunction, or not function at all on one or more of the settings.
What happens if a heater blower has no power?
A blower motor without power will not be able to produce any air pressure, and as a result the heating and air conditioning system will be left with no air coming from the vents.
If you have a vehicle with climate control system and a variable speed blower motor and the blower motor won’t shut off and stays on HIGH with the car turned off and the key out, chances are the blower motor motor control processor is toast or the HVAC control module is damaged.
When to replace the blower motor control module?
Important: Replace the blower motor control module if the vehicle experienced a blower motor control module failure in extremely cold ambient temperature conditions. Technicians are to replace the blower motor control module, also called the Linear Power Module (LPM), with the P/N listed below.
Where does the power go in a blower motor?
For each higher speed, power flows through one less resistor. Some car makers run blower motor power through the fan speed switch first, then through the blower motor resistor and then to the blower motor and ground. Other car makers reverse that and run power to the blower motor first and terminate ground at the blower fan speed switch.
What happens when a blower motor resistor fails?
If you’ve replaced a blower motor resistor and that replacement has failed, it’s time to conduct an amperage test on the blower motor. If the amp draw exceeds manufacturer’s specifications, replace the blower motor. can also cause an overheating condition. In some cases, the heat is so high that it melts the connector.
