Ok I have been trying to solve a blower motor problem. I have a new blower motor, a new resistor, a new control switch panel, a new relay, and a new fuse. I get no voltage (when checking with multimeter) on high setting at blower motor connector, purple wire. I do get voltage when testing at connector (purple wire) at the low settings. The black ground wire there is good. When I use a jumper wire at relay terminals 30 and 87 I get the motor to run, but it will run with key off and with key on. Strange! I just not sure what to do next. When I test at relay terminal I get 87 terminal hot at all times, when I use low heat settings I get voltage at 87 and 87A(resistor). When I put it on High I get voltage at 87 and 86 ( Switch) My ground 85 is good. Going crazy. Please Help!
have the same problem?
