Question about 1991 Dodge Dynasty
I went to replace the blower motor, and once the new one was installed its not working. All fuses were ohmed, even the one under the hood. During a voltage check there is no power coming to the wires for the blower motor, even when the switch is on high with a/c running. What am I missing?
Check the blower motor resistor located behind the windshield washer fluid. just replaced one and it worked.

Trace the two wires by analyzing which power are you missing...
run a wire from the positive of the battery and put the red wire of the volt meter to it and place the black wire of the meter to the black that goes to the motor.
if there is 12 volts, you have a negative terminal to the motor.
if you dont have, then you dont have the negative terminal to the motor.
next transfer the wire from the positive terminal of the battery to the negative terminal of the battery.
now put the bllack wire of the meter to the wire and test the red /or blue wire that goes to the motor.
it should have a reading of 12 volts.
if there is no reading , then there is no positive 12 volt present on the blue/red wire.
from these test, you can know which wire does not have the power.
that is what you are missing..
tnx 4 using fixya,
you could have just missed the black wire to be screwed on the housing of the blower motor.
