Help with blower moter on 1985 RX7
Not sure what is going on but the blower on my 1985 Mazda RX7 quit working. I tried the fuses and nothing. Does anyone else know how else to trouble shoot this problem? I hope that I do not have to replace the blower motor. I have seen similar blogs but no one seems to know the answer. If no suggestions how hard is it to replace the blower motor? Please let me know. My mail is Curtis.wright.9@us.af.mil

I would unplug the connector at the blower motor and turn the fan switch on. Using a multimeter, test for 12V at the connector. If you have 12V, pull the blower motor, which is super easy, and apply 12V directly to the blower motor's pins and see if it spins. If it does not then it has failed. If it does spin and you have 12V at the connector for the blower motor then the motor should spin. If you do not have 12V at the connector, you need to test the fan switch and inspect the wiring from the switch to the blower motor.
