Question about 1984 Pontiac Fiero

1984 Fiero Electic Fan issue

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?

    That would be the radiator fan assembly

    So, help me understand - with the single speed fan that I have, the resistor is not needed? Or going back to a 2 speed fan w/resistor will solve the issue? Would you now the rating/specs for the resistor? Thanks for the info,

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

Mini cooper fan keeps running when key is turned off and enngine is not hot

The resistor on the fan is bad. You can purchase a new resister or buy a new fan assembly. Mine did the same thing and I just purchased the whole fan assembly and changed it out. to change the resistor, you have to take the fan assembly out. So I just changed the whole thing.

High fan does not work on a c or heat 1985 jimmy g m c

You most likely need to check and replace your blower motor resistor assembly. It is mounted in the heater core plentum assembly, and has a wire harness that runs from the resistor to the blower motor. Look over the connector plug to make sure that it isn't corroded and overheated .

Blower motor will not shut off

I can't speak to the cost, a local dealer can do that. As for the reason the fan runs on, it sounds like either a stuck power relay (location should be in the owners manual) or a bad fan speed regulator. Since the fan is stuck on high, I suspect the fan speed regulator is bad. On some cars the regulator is part of the fan assembly, and on some it's separate. Also, there is a possibility you can repair the circuit board, assuming it's something as simple as a burnt out diode. Best of luck!

The heater fan on my 1993 f-350 has become really loud. I only have hi speed which I understand may be a resistor issue but how do I remove the fan and motor assembly to inspect it?

A heater blower motor resistor is an electronic device with three or more progressive resistors that allow the heater blower motor to operate at slower speeds. The highest speed of the heater blower motor is not controlled by the resistor, so when the resistor fails, the fan will often work on the highest speed setting, but not the lower speeds.
To resistor is generally located under the dashboard and under the hood, near the blower motor . The resistor's electrical connector is disconnected, the resistor is removed and the new resistor is installed. On some vehicles it may be easily accessible, and on others it may take partial dashboard removal to replace the resistor.
Look under the hood, generally the wiring for the Blower resistor is attached to the wiring to the blower motor itself
It's inboard & below the motor, near the accumulator. You can see it standing beside the passenger fender. it's the off-white connector behind the L heater hose above the vacuum reservoir & the white WARNING sticker

Replace fan speed switch

Before you replace the fan speed switch...make sure you check the fuse...then check the motor...and finally check the resistor assembly...the resistor assembly controls the different speeds of the fan motor by allowing the switch to put different resistors in and out of the circuit to reduce the fan is usually located on the heater housing near the fan motor..they are a common failure...the switches don't fail as often

A/C Heater blower fan does not cycle through all speeds

Yes it is the blower Motors Resistor board. It is up behind the blower motor, just under the glove box. You have to remove the black KICK panel with its two "Push Pins" that will break too. There are 3 screws holding that resistor board in, the back two are a bear to get to. Good luck.

2005 Pontiac Vibe heater fan working on high only

My 2005 Vibe did the same thing it was the heater resistor. It is located to on the firewall behind the glove box on the lower left side of the blower assembly. Two 5.5mm screws hold it in place (1/4 inch socket works too). I used a socket attached to a socket swivel to replace mine in under 10 minutes. Heater now works as good as new. I purchase mine online for $30 from rockauto.

A/C blower fan blows at about half speed

Hi. this is a blown resistor switch. it is located on the actual dash cluster control assembly.(speed selector switch). replace this failed switch asap.

A/c fan only works on the highest setting...not the lower ones

A/C fans only really have (2) speeds. (0)Off... and (4)On. Settings 1,2,and 3 are governed by a series of two resistors which in combinations (one, the other...then both) can limit the speed of the fan. When the circuit with these resistors goes bad, the middle speeds of your fan will cease to work. Since the highest setting is unresisted it will never stop working... unless your fan fails.
The solution is economical as these are simple inexpensive parts. For simplicity, the panel with the resistors is typically located in the dash, right behind the speed selector knob. It may be an integral component with the knob assembly depending on your manufacturer. Replace the assembly, or simply the resistors if you are lucky. On the bright note, it doesn't sound like you need to mess with your blower moter... its fine.

Cheers, unclouded.

A/C fan switch only works on high. When this first started it would work sometimes on the 3 other settings when it wanted to. Now it only works on high. The Dealer ship service department told me that it...

The solution was replacing the plug leading to the resistor. It is part number pt1231 from acdelco. I highly recommend this and am 99% sure that this is your solution. thanks
