No power to blower switch
Blower not working 07 250 van. no power at switch
<hr size="1" style="color: rgb(209, 209, 225); background-color: rgb(209, 209, 225);"><!-- / icon and title --> <!-- message -->
I have a 2007 250 van and the blower control switch is not working on any speed. I took the dash plate off and checked for power at the switch, and I do not have power to any wire behind the switch. I do not think it is the resistor under the hood because I do not even have high speed working. Can anyone help me?
Thank you in advance

Hotshot
The blower speed switch is on the "low" side of the motor on your van. Any open circuit upstream of it, the motor, the relay, or BJB fuse F17) will cause your set of symptoms.
Start by checking the power at the two motor leads (Ign to Run, Mode switch not on OFF, speed to med-low). ORG/RED should be battery voltage. ORG/BLK should be anywhere from 6 to around 8 volts.
What do you measure?
