Ok, heat was working A1 perfect last year, especially with the Superstat I put in it.
Here we are in the present, Artic Blast and I've deduced that its a fuse somewhere I can't see or the a/c heater panel switch, because my blower motor won't come on, on any of the four speeds.
I have test lighted and the found the following:
The red wire going to the underhood big silver shelltop relay is always hot (constant). No other wires (purple or blue) are hot at anytime.
The wires going to the resistor is not showing hot constant, nor switched(on ign).
Inside the dash, I pulled the heater a/c control panel out slightly to test the two switches.
There is a mode switch (heat, vent, etc) and the blower motor speed switch (low, medium, high).
I found that the i'm getting switched hot on on of the mode switch wires.
But the blower motor speed switch has no hot wires constant nor switched.
I know the actual blower motor works, I ran a hot wire to it and it came on.
Pretty sure its not the relay, nor resistor, because as you can see, I don't think power is getting to them
All the fuses in the fuse box are not blown.
