So, a couple of weeks ago, I noticed a slightly warmer running temp. The needle was reaching the middle of the 0 in the 180 marker. And usually this would be when driving at low speeds.
My initial instinct was something having to do with the cooling fan. So, I pulled over and listened and as suspected, the passenger side fan was off while the driver side was blasting away. I reached out to one of the RL members and he helped me do some trouble shooting. (Thank you!)
Fuses and relays were OK. So the primary culprit was the cooling fan. However, my brother suggested that we test the resistor and know and behold the fan works but the resistor is bad. So instead of buying a new fan, he is suggesting replacing the resistor if it makes sense. I've attached a picture.
1. Where can I find and buy this?
2. Has anyone done this before rather than replacing the entire cooling fan?
Those regular power resistors with the proper wattage will work. The only concern I have is how to weather proof it properly given the location of the resistors and how they are exposed to the elements, rain, road salt, etc.
Of course the above shouldn't concern us Californians

Definitely something to think about. Although, I must admit that the car will probably never see salt and very little rain.
Considering how often that area gets splashed, you definitely need to protect that resistor.
Definitely check the fan operation first. Run a positive and negative 12V to the fan direct connector and see if it runs. I had a '97 Boxster that had two bad fans, so they can fail.
says "can be used in atrocious environment" ... It's an anodized aluminum shell, so it should be ok as long as you make sure the leads are well covered/protected.

We did. We supplied power directly to the fan through the connector and it worked just fine.
As electronics are not my strongest suit I am also interested in adverse effects. For example can one expect adverse affects on other electronic components if not using the factory resistor in this case?
