What happens if there is no power to the blower motor relay?
If there is power into the blower motor relay, but no power to either the blower motor resistor or the blower motor itself, then the relay is bad. If there is no power to your blower motor relay, check your blower motor fuses.
Why does my blower quit when the motor quits?
Eventually the blower quits completely. It may be that the relay failed on yours right away instead of dying a slow death like mine. If you’re having problems finding which one it is, shoot me a PM with your email address and ill send you a pic of it. Installing a new relay may fix your problem Wrxmechman. The trouble could be with the motor also.
Can a malfunctioning blower motor send 12 volts?
If the resistor is not doing it’s job, it is possible that it will just send 12 volts through, or just be off at 0 volts. So if it is in fact a malfunctioning blower motor resistor, this could be a possible situation. It is interesting your info shows the resistors in line on the power lead before the connection to the motor.
Where is the blower motor relay on a 1993 legacy?
On my 1993 Legacy, the blower motor relay is located underneath the driver’s side dash panel, where all the wires and junk are. If your car is anything like mine it will be on the left side close to the fender. The blower motor relay is just a white color, and it looks similar to the fuel pump relay which is green.
