found this
apparently the resistor is only used for the lower 3 speeds on the heater for your car. try this out
Find the blower motor high speed relay. It will be a small box near the blower itself. You can follow the thick purple wire from the blower to the relay. The relay will have a couple of small wires, the thick purple one, and a thick red one. The red one feeds raw battery to the relay, which then feeds it to the motor, thereby bypassing the ENTIRE rest of the car's wiring and delivering the highest possible voltage to the blower. Or, maybe not.... follow the red wire away from the relay. It will go up, to the windshield cowl, and over toward the driver's side. About at the point where it reaches the pass side valve cover, you will find a connector. Disconnect that extremely stupidly designed connector and observe that it has burnt completely to ashes, like everybody else's. There's your problem, same as everbody else.
Cut that idiotic thing off; and replace it with a pair of the BIG THICK HEAVY-DUTY yellow slide terminals. Not, the little weenie ones that are just like the blue and red ones except with a yellow barrel; look for the BIG THICK HEAVY-DUTY ones. Try to find insulated ones if possible. If not, cover the outer one with a piece of heat shrink.
