I’m having a bit of an issue with getting the heater blower to work...
The motor bench tests fine The wire on the heater control lever is connected correctly When I pull the lever back, I can hear the relay clicking in the engine bay However, when I connect the fan to the heater wire the motor does not run. I confirmed that brown connected to brown and green to yellow, just like the picture below. I was holding the motor - so it wasn’t separately grounded - would that be the issue? Any ideas ?  |

Pretty simple circuit to troubleshoot. Lever pulled all the way up, connects relay to ground. Should be 12 volts at relay. Using a digital volt meter or analog meter, check for power and ground at the blower.
