Check the fuses, fuse 1 (40 Amp) in the Power Distribution Center under the hood. One side of the blower motor goes straight to ground...via the various resistors in series in the resistor block....Black/Tan wire. The other side from the fuse, Red/Light Blue carries the +12 volts.
If you have a meter check that this +12 volts is on the Red/Light Blue wire with respect to ground.
If you jumper pin 30 to pin 87 in the Blower Motor Relay socket the blower motor should run unless it is missing the ground or has burnt out. If this does work then there is something wrong in the relay area.
