BTW, here are the resistance values supplied by the card, apparently from some service manual. My findings (below) differ.
Looking at the card (into the connector jack), the card has a clipped (45 degree) corner. The pins are numbered 4-3-2-1 from the clipped side to the square side.
2-4 1.2 to 2.6 ohms
2-3 0.3 to 0.4 ohms
2-1 0.9 to 1.0 ohms
My 2010 Escape, post January manufacture date:
Looking into the connector terminals on the card, pins are numbered (square corner to angled corner) 1-2-3-4. Looking into the harness plug with the latch side facing down, pins are numbered (left to right) 1-2-3-4.
- Green/White (switch – medium high speed)
- Violet/Orange/Yellow (ground)
- White/Brown (switch – medium low speed)
- Black/Green (motor low side, switch – high speed)
The motor, switch, and resistors are on a dedicated 40 amp circuit.
These values are from a Ford issued schematic identifying the card as 19A706, and are very close to what I meter on the (new) card for my 2010.5 Escape.
