I have a 2005 Pontiac Wave.
I've noticed what looks like a resistor in the engine bay, underneath the battery.
It's ceramic, couple inches long with one wire in each side.
It's clearly falling apart, but I don't know what it is, which makes it hard to order a new one.
If anyone knows what this is let me know.
Thanks
i know the part you are talking about, i thought it was a fuse-able link at the time. But i have not come across it in any of my manuals.
You don't mention any problems with your car. Why do you want to replace the part?
Take it off and leave it disconnected, see what doesn't work. I think it would be for the headlights, but not certain.
I think it might be related to daytime running lights,which periodically don't work.
Or it might be related to engine cooling fan, or A/C operation.
Like I stated, it's clearly crumbling from water/frost damage. I'm hoping it might help with daytime running lights or that it might prevent some issues down the road.
It's not likely for A/C or any other cooling fan. I don't have A/C and my car has that resistor. I doubt it's for the fan because those are normally 12V and would not benefit from it.
Where is it located? Trace out the wiring. Or disconnect it and see what doesn't work. You can eliminate the internal heater fan witbout even starting the car, just turn it to run.
its not the drl, that has a box on the inner firewall.
i agree with it most likely not being the fan, etc. the only thing i can think it might be is a ground resistor for the 5v signals. But that seems highly unlikely. I have to admit i was sort of surprised when i came across it too.
I will have to find the DRL resistor, if I can bring that signal up to 12 volts, I will change my DRL over to LED's or something.
What are 5v signals?
Do you have any manuals showing engine cooling fan circuit?
I think it might be related to that.
Thanks
ENGINE COOLING MOTOR RESISTOR.
Finally got it.
the PCM provides a 5 Volt reference Signal that runs through all of the Sensors that do not have their own power source. the sensors then change the Reference Signal according to what they do. that changed signal then Goes BACK to the PCM and is processed as the reading for a paticular sensor.
that ceramic resistor is for the radiator fan speed, it controls the speed on the radiator fan so its very important regardless that you have AC or not, i would not disconect it or otherwise, if its coroded and broken i'd replace it its only 24 bux at the dealer, and also will make your check engine come on due to low/poor voltage circulation , hope this helpsQuote:

HTHY
well that's interesting because my 2008 aveo5 SV has that same resistor, and did not come with A/C? The resistor is also on the wrong side of the car...
94812213 That is the oem part #. Its a radiator fan ballast resistor. They have two speeds on the fan on the radiator. I had to hunt like heck to find out what it is. On the wire diagram it shows up. The ECM controls it. I have noticed my fan not spinning fast and thought it was going bad. Mine at last cracked and burned out. Car still cools just fine but am going to replace it. Its 17.00 on Amazon. This has drove me nuts also and I also was hoping this was the daylight running lights. Its not. Those dam things still working but not after this weekend. LOL>
here is a diagram showing that mistery ballast under the battery. Low speed for the radiator. Thats just stupid.....http://www.justanswer.com/uploads/mo...44756_aveo.gif[/QUOTE]
It's for your cooling fan, comes from pin 87 of the low cooling fan relay and then to the cooling fan.
I have the 2005 manual and that page is labeled wrong, it doesn't include the 1.6 liter which has the resistor also.
Following the wire from the ceramic fuse i come to the conclusion it's for the fan. Yes the fan is 12v but it is also a 2 speed fan, so the ceramic fuse drops 12v down to 5v to change the fan speed.
location, pleaseQuote:
