Question about 1984 Pontiac Fiero
Hi - after I had my fan assembly replaced with a Hayden 3700, I noticed that the resistor was not on the new assembly. I was told that it was not needed any more. The new fan was wired to the connector that leads to the fan relay (the resistor would have been between these 2 components) with a wire spliced in to ground.
The fan worked for a day or 2, then the ground wire burned out. BF temporarily wired to fusebox, which I don't like so I drive minimally. Do I need to replace the resistor again? If so, what are the specs for resistor and best place to buy OR what should I do now?
I would try to find the right fan setup the reason that resistor is there its really a speed control
at 185 the fan turns on low at 227 the fan then goes into high
i just went thue this on my 84

Your Buick Riviera's heater fan is powered by a blower motor, which in turn is powered by a blower motor resistor. The resistor is a small electrical component that also regulates the fan speeds of the blower motor. Like any part, the blower burns out from time to time and has to be replaced. Replacement blower motor resistors cost about $50. It will take you about 30 minutes to install a new one in your Buick Riviera.
Things You'll Need
Open the hood and disengage the negative battery cable on your Buick Riviera using your socket set. You will need a 10mm socket to loosen the battery cable bolt.
Remove the plastic trim panel under the glove compartment on the passenger side of your Riviera.
Loosen and remove the mounting screws that hold the blower resistor in place on your Riviera.
Unplug the wiring harness from the old blower resistor and then remove the resistor completely.
Plug the wiring harness into your Buick's new resistor. Also tighten the screws to hold the resistor in place.
Reattach the negative battery cable on your Riviera and tighten it with your socket set.
