Hi, I have a 2006 Kenworth W900. A/C fan not coming on. The attached pictures shows the wires I have tested. Starting with the white wire on the left.
White wire: No power
Green wire: Touch it with a test light and the fan goes on
1st. Blue/Black wire: 11.9 volts
2nd Blue/Black wire: 11.9 volts
Far right White wire: 11.9 volts
The resistor controls the high and low knob, correct?
Thank you.
