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

wonder if it goes into that other thing?

might check blower motor resistor

 

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)?

 

Doesn't go into there, I've found what It's to. Note the female end is still stuck to it.

It's for the a/c button

 

Battery voltage applied, motor does not work. I've taken apart the motor, and will post pictures of motor repair.

 

Murphy's law, it's cold out!

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.

 

Unfortunately, I no longer have probes. I will test with a lamp.
