Heater stopped blowing

Found this line disconnected, it has something to do with it I'm sure. Stopped blowing suddenly, fuse is good, relay clicks.

You can also apply battery voltage to that plug going directly to the blower motor and rule the motor itself out.
Could be the resistor, does the fan work on any of the 4 speeds (after you plug it back in)?

Seems like you found the issue to be the motor. I assume you are getting the proper voltage if you turn the fan switch on and probe the blower motor harness? Just an additional check to make sure everything else is functioning as it should while the motor is out.
