Disconnect A/C clutch connector. Set DVOM on 20-volt scale. With KOEO and A/C on, measure voltage between input pin on fan connector and test pin No. 40 at the breakout box. If voltage is greater than 10.5 volts, go to next step. If not, repair open in A/C circuit. Remove breakout box, reconnect all components and repeat QUICK TEST.
