KevinW Posted June 14, 2004 Report Share Posted June 14, 2004 On the blower connector, check for B+ on the red wire and ground on the black wire. The control circuit (GRY/BLK) should be over 9 V when LO blower is commanded and below 4.5 V for HI; measure using a high impedance voltmeter. ___________________________________________________ Link to comment Share on other sites More sharing options...
