I have replace the blower switch pigtail rerister still no blower working could it be the relay if it is where is it ? the blower motor and relay are the only two things left to change need help thanks

Do you have power to the blower motor?

With everything connected there should be power on both wires going to the blower motor. If there is no power than remove the blower motor relay in the fuse block under the hood. There should be power at two of the pins and two of the pins should be grounded. One pin is powered by the 50 amp Blower fuse and the other gets its power from the function selector (the switch that controls where the air comes out.

If only one pin has power than pull the 50amp blower fuse If power goes away than you know that the relay is not recieving power from the function selector. That is powered by a 15 amp fuse in the cetral fuse block (under the dash i think). If that fuse is good than check for power at the pink with black wire at the function switch. If there is power there tan check for power at the yellow with red wire and the function switch. If there is no power than you have a bad function switch.

This is a ground side controlled blower motor. The speed switch controls the path to ground. so if there is power to the blower motor on the orange with red wire you can ground the orange with black wire at the blower motor and it should run.

That should be enough info to get you started. Let me know what you find and I'll be happy to help further.
