Why Does My Blower Only Work On High at Aaron Casey blog

Why Does My Blower Only Work On High. This problem is a classic blower motor resistor problem which is common on vehicles that use manual fan speed switch. It is best to have a professional diagnose and fix the issue. This is from a high heat situation and is causing a high resistance connection that sometimes prevents the blower motor resistor from operating properly. The resistor array on newer vehicles is often done on a pcb style board which are extremely prone to failure. Does your blower motor/fan only run on high speed.or not at all? Does your blower fan work on the high speed setting only? There could be several reasons why your ac only works on high, including a faulty blower motor resistor, a malfunctioning fan control switch, or a clogged air filter. The resistor pack is used for all speeds except for the fan's highest. The fan only working on high is normally due to a defective resistor pack. When a blower motor only works on high speed, it usually indicates a problem with the blower motor resistor, which controls the fan. If your speed selector for your ac or heat only works on high, or low, or if its missing any particular speed, this video will show you how to. In this video, we talk about the cause and effect that leads to blower motor.
