no power to blower motor

Thank you for the help in locating the blower motor relay. Have changed heater selector switch, resister, blower motor relay. Removed old blower motor tested good but looked bad, very dirty. Did not reinstall old blower motor waiting on mail for a new motor. Made all the other connections and no power. Could not find power to any of the connections with engine running. Old school says likely a bad ground. Where could that be? Stumped. regg

model, year, AC or no AC.

When I see the price of OEM I think aftermarket.

The place to start is to check for both 12v power & ground at the blower motor connector.

With the key on & the mode switch turned to any position except off check the dark green wire for 12v & the black/tan wire for ground. That will tell you where to go next.

Deviations of power supply parameters from the norm can be for several reasons: transients, interruptions, voltage dips, voltage dips, voltage surges / overvoltages, voltage waveform distortions, voltage fluctuations, frequency variations. Check all these parameters
