ok so i have no air blower through the car, (heat a/c defrost) nothing...

it has been sketchy making weird noises for days now, sometimes working some not... when it would it was weak and making noises... then went away but came back when i turned the air flow knob "(the one on far right) now is gone completely

WHAT I HAVE DONE

1.) pulled the blower motor out and tested it... FINE
2.) resister looked bad so i replaced it... STILL NOTHING
3.) checked relay and fuses...ALL FINE STILL NOTHING
4.) pulled climate contol unit apart checked connections and vaccum leads,, from what i can see FINE...

it probably is going to a shop tomorrow since its 14 degrees out and i have to heat......

ANY ideas?

Check for voltage on the connector that plugs into the motor.

Thats how I determined it was the motor that was bad not the resistor.

The motor would also work, make noises and slow down.

So you replaced the resistor and not the motor???

When it rains it pours in the car world. Did you really think you'd get away with only one thing going wrong?

anything obstructing the rotation of the fan when it's mounted in place such as a bad housing, etc.?

^ And if you kept trying to make the window go up/down after it broke you more than likely F'ed the regulator.
