Jim Cannon Posted November 21, 2010 Share Posted November 21, 2010 Check fuse.Will the fan work on High speed? If so, but not on other speeds, check resistor block under hood.Try connecting 12 volts directly to the fan to rule out motor.Use volt meter at resistor block to see if power is making it out to that point. If not, check fan switch.Jim Link to comment Share on other sites More sharing options...
