Hi, I am having blower motor issues. I have a new blower motor, new resistor and control switch, I have checked the fuses and relay, all good. When I check for voltage at resistor connector, I get voltage on all the settings, but when I check for voltage on blower motor connector, I do not get any voltage( purple wire). I checked the ground( black one) it is fine. Don't have any clue what to check next. When I jump the motor to battery it spins.

Did you check the circuits at the blower motor relay? Any applicable fuse, you need to check voltage on the fuse circuit.

Do you mean the hi blower fuse 30a or the actual socket where the fuse goes into?

If the fuse has a bare spot over each leg, use a voltage tester on each leg. If both are hot so far so good. Check this fuse, also. Notice the fuse goes hot with the key on.

Hi, I just checked to see if any voltage from fuse box at 30a hi blower fuse. I did not get any readings, I pulled different fuse and checked that voltage, is was good. How do I fix this particular problem? Should I replace something, the wire going into the fuse box for that particular fuse?

The 30 amp fuse, should be high speed only. You see the relay diagram, when the relay is not energized, there should be continuity for lower speeds, none of the speeds work?
