According to my schematic, check first the blower fuse 40amp in underhood fuse block. With a test light to ground, check for power at blower resistor terminals G, B in lo, A in med 1, D in med 2, C in med 3, and F in hi. Check for ground on pin E. If you could use this ground to ground your test light when checking the above, it will validate it. If you have power and ground (the resistor can be disconnected) on these, and no power or ground to your blower, than replace the resistor. The resistor is shown attached to the blower motor.
